RoadTest: Texas Instruments Educational Boosterpack II

Author: balearicdynamics

Creation date:

Evaluation Type: Independent Products

Did you receive all parts the manufacturer stated would be included in the package?: True

What other parts do you consider comparable to this product?: This is the first TI boosterpack I have used, so there are not other possible alternatives I had the option to put the hands on. Instead respect the TI launchpad, the "brain" and base of the entire ecosystem, in theory comparable alternatives are other microcontrollers like Arduino, LinkIt One and other devices but in my opinion by a technical point of view there is nothing to do with this board. I should admit that considering all the aspects including price and features the launchpad is impressive.

What were the biggest problems encountered?: The biggest problems has been some software issued in the development kit libraries that needed some days to be set working correctly.

Package content


This road test is focused on the TI Launchpad MSP432TI Launchpad MSP432 board and one of the components of the ecosystem rotating around this device: the Educational BoosterPack MKII As I am used in many other cases, the box including the bare hardware and a small instructions single paper sounds absolutely normal. Both the devices appears very well done and the first look perception is really nice.

A very appreciate detail is that the included paper shows the essential information to manage the board; the same document can be downloaded from the launchpad TI site too, but having it printed has been very useful in more than one case.


After the justified enthusiasm, the next step is to power-on the printer and see what happens image

Introduction to the MSP-EXP432P401R launchpad board

The first attention was to the MSP-EXP432P401R launchpad board. It's small and complete, with some appreciable components. My personal opinion is a class A development device very good for teaching, advanced makers and engineers and in the meantime may result very useful for all those that are affording the first approach to the world of micro controllers; in a good balance between a lot of performances and a very good price.


The availability of the design files in different formats including board and schematics for Eagle (and the gerber files too), makes this board the ideal base for the development of any custom project.


  • MSP432 Low-Power + Performance 32-bit MCU
  • A total of 40 exposed PINs; some of them become reserved when one or more boards of BoosterPack Ecosystemare added to the launchpad board (the BoosterPack boards are stackable).
  • 8 analog-in ports
  • 1 available UART (Tx/Rx)
  • 2 capture timers
  • 5 PWM
  • 1 SPI bus (with three dedicated CS PINs)
  • 1 I2C bus
  • Reset PIN
  • 2 GND PINs
  • +3.3 V power line
  • +5 V power line
  • The remaining PINs are standard GPIO, interrupt capable


Most of the dedicated PINs (i.e. SPI, PWM, UART etc.) can be used as GPIO PINs as well.

Special attention has been put to the low energy capabilities that are not only peculiar of the MSP432P401R microcontroller but also the entire launchpad board. As a matter of fact it is surprisingly that the board is built in two parts. The bottom half respect the micro USB connector is the launchpad board while the top half is the circuit of the XDS110-ET on-board emulator including the Energy Trace Technology implementation. This design can incredibly simplify the development and debug process, always with special attention to the power consumption.

More in-depth details on the launchpad board can be found on the ti.com site at the following link: MSP432P401R LaunchPad - MSP-EXP432P401R - TI Tool Folder (maybe you should be registered to access the technical details of the site products and devices).


What happens running a project based on this board to the emulator and the energy trace circuit board ? The two half boards (or, better the two boards on the same PCB) can be isolated through a series of jumpers converting the board from a lab development kit to a effective prototype working board. The jumper settings are shown in the table below.


Based on the first tests I have done on the board, without connecting an external component the entire system was full responding with high stability. This board demonstrated very good performances also with A/D conversion  supporting up to 14 bits thanks to the 14-bit SAR ADC, capacitive touch, comparator.



To simplify the usage of the board with any project, the 40 PINs headers are replicated on the top and bottom side of the board while - a detail not included in many other development kit boards - the all other unused PINs of the micro controller are accessible on a unpopulated fanout along a side of the board.


Introduction to the Educational BoosterPack MKII

Confirming the first impression I had unpacking the board the term Educational is very well deserved. A relatively small board including a well designed educational lab that can replace a variety of single shields. The MKII list of the available sensors and components is impressing:


  • 2 user programmable push buttons
  • 2 axis analog joystick with pushbutton
  • 1  good quality microphone
  • 1 colo TFT LCD graphic display
  • 40 pin stackable connectors (to the side of the LCD display) to plug the BoosterPack in the launchpad board
  • 1 buzzer
  • 1 RGB LED
  • 1 3-axis accelerometer
  • 1 3-PINs servo motor connector
  • 2 capacitive connectors (GND and PIN)
  • 1 temperature sensor based on the TMP006, high resolution sensor
  • 1 light sensor OPT3001, very far from the light sensing variable resistors we find in many projects. With this light sensor there is a wider range and it is possible to use if for many applications including - for example - a light exposimeter




The educational BoosterPack has been tested and all the components worked fine in different configurations. All these components on a single board with the advantage of simplicity to plug it in the launchpad is very useful for experimenting; I think that just the two components, a PC and the USB cable to connect the kits to the computer without extra cables, breadboard etc. makes this product, first of all ideal for educational purposes.

Making an almost complex project another appreciable aspect of the board is the distribution of the components making is a really usable tool.

As well as the launchpad alto the Educational BoosterPack MKII is open source and on the ti.com site (the MKII page link is  Educational BoosterPack MKII - BOOSTXL-EDUMKII - TI Tool Folder) a large number of downloadable documentation is available that I rarely find on other dev kits. Depending on the reader target it is possible to fin easy to use documentation, first steps and detailed application notes up to the datasheet of every used component.

Should be noted that also that making several tests on the launchpad board with the BoosterPack plugged in it is not difficult to find other available analog and digital PINs available as well as PWM outputs and analog inputs. By this point of view the MKII really represent a full working almost complete development and experimenting lab.



The MKII board has demonstrated to have not serious issues and all the components worked fine. In my opinion, maybe it was the case to add two servo pin headers instead of only one; this limits the use of a single servo for simple experiments. There is the advantage that all the PINs used by the MKII are anyway accessible from the launchpad free header connectors.

Another really noisy detail is the association of the buzzer to a PIN. This reduces the usage of a PWM output and it is impossible to disable it. Developing a test project with the boards I had to desolder the buzzer to have the PWM output free without the associated noise while generating frequencies.

When the BoosterPack is plugged on the launchpad board unfortunately the reset button, natively present only on the launchpad board, is hidden by the board and it is impossible to access to it. If a hardware reset should be sent to the board, it is needed to use the reset pin.


Software tools and examples

There is an appreciable and interesting aspect in the software tools available to develop on the TI launchpad and the ecosystem: the availability of different kind os development platforms to support beginners and advanced developers. The two most interesting tools covering both the possibilities are Energiahttp://www.ti.com/tool/ENERGIA?keyMatch=energia%20software%20download&tisearch=Search-EN-Everything and Code Composer Studio. The first tool is a customised derivation from the popular Arduino IDE, running on all the desktop platforms Linux, OSX and Windows while the second runs on Windows only and is a customised version of the Eclipse IDE integrating the launchpad on-board debugger and a plugin to manage the proprietary Energy Tracking Technology.

With Code Composer Studio it is possible to develop complex and structured projects exploiting all the potential of the launchpad board.

For the beginners, eventually used to the Arduino class micro controllers, there is Energia. It is a well known development tool that has been revised (and in most of the parts totally rewritten). The Eneriga setup installs all what is needed to start immediately developing with the launchpad and the BoosterPack MKII.


The Energia IDE worked fine with almost all the included examples but a blocking issue makes impossible to use the colour LCD display of the BoosterPack MKII. The post TI Educational Boosterpack MK II and Energia, part of this road test, discusses the issue and a workaround to solve the display bug.


Playing with the TI BoosterPack MKI


To experiment the features of the two boards I have developed the TiltPan Moving Camera prototype, GoPro version exploring the features of these two components of the TI BoosterPack Echosystem in a real case. The video below is presenting the obtained results. A more detailed presentation of this project including the adopted software approach and the general performances will be discussed in a separate post.

  • Hi Enrico,


    Yeah I've observed the same issue with the cheap continuous rotation hobby servos : ( Looking forward to seeing all the prototypes you mention and the resulting camera effects!

  • Thank you Shabaz!


    As a matter of fact there is an algorithm very similar to the acceleration/deceleration mechanism adopted in the CNC and 3D printers to make the movements fluid. I have used the GoPro with a logic, to make these experiments. As the focal plane is almost to the focus of the two movements it is perfect to make experiments on stability as any minimal defect that with a common camera is difficult to see here is amplified; the alternative will be the use of a long distance camera lens but GoPro is a good balance between shooting quality and dimensions.


    Remain an issue in this project that is almost out of my control and I think there is no way to solve it with the servos only; the base servo is a continuous rotating servo but - due it's poor quality I suppose - it is very difficult to make it stable when not moving. I will detail all these things in a separate post but the final version of the project will be forked in two. One - ideal for small cameras and stop-motion application (with cheaper components) will use two servos, both standard 180 deg. only. The other with the full rotation base will use instead two NEMA17 stepper motors supporting up to 5 Kgs weight device. This project is part of a series of prototypes I am doing creating a set of low-cost camera motion tools, including the Tilt-Pan, a sliding rail and a gimbal.



  • Hi Enrico,


    Great review, and great project - and awesome video! That control method worked very well, nice motion are possible with your project.

    Also, very neat to see the video with the camera output overlaid with the view of the camera in its mount : )

  • Thank you DAB, this is one of the issues of the site image (I stopped to mention, better to wait the new site change). After I pressed the "save as draft" this is what I got image image image And few days ago I received the notification of a new road test published, but when I opened it I read all the I saw it was in draft mode. Obviously from another user.




    P.S. I'll notice you as I finish writing the review.

  • Good start.


    I will be watching for your more detailed assessment of the 432 board and the education kit.
