About the RSL10 Dev Board

The RSL10 Evaluation and Development Board is used for evaluating the RSL10 SoC and for application development.




About the RSL10 SoC

RSL10 is a Bluetooth 5 certified, multi-protocol radio System on Chip (SoC) which brings ultra-low-power Bluetooth Low Energy to wireless applications. Offering the industry’s lowest power consumption, RSL10 helps provide devices like heart rate monitors with advanced wireless features while optimizing system size and battery life.


Unique Features of the RSL10

Unlike most other multi-protocol radio SoCs, RSL10 is specifically designed for applications using 1.2 and 1.5 V batteries, and supports a voltage supply range between 1.1 and 3.3 V without a required DC/DC converter. The highly-integrated radio SoC features a dual-core architecture and a 2.4 GHz transceiver, providing the flexibility to support Bluetooth Low Energy and 2.4 GHz proprietary or custom protocols. the RSL10 SIP, Fully-integrated System-in-Package (SiP) for easy designing


RSL10 Features


- Industry's lowest power consumption in Deep Sleep Mode (62.5 nW) and Rx in Receive Mode (7 mW)

- Industry's best EEMBC® ULPMark™ scores (1090 ULPMark CP @ 3 V; 1260 @ 2.1 V)


Advanced Multi-Protocol Wireless Functionality:

- Rx Sensitivity: - 94 dBM

Comment List
  • To all roadtesters,



    If you posted a review, I'd like to thank you.


    If you have not, please post it now. It's overdue


  • This board looks very useful!

    According to the documentation, it contains an ARM microcontroller chip with Bluetooth LE capability, called the RSL10, and a JTAG type of debugger chip, so that nothing extra is needed for trying out many things. The software development kit allows for C programming, using an Eclipse integrated development environment (IDE).

    Much like an Arduino, there is a USB port for connecting to the PC for programming it up.

    The RSL10 chip contains more than just microcontroller functionality though.


    As far as I can tell, it can serve several purposes:


    1. As a general-purpose ARM microcontroller (shown in purple in the diagram below), it has a Cortex-M3 chip, with lots of memory - around 88 kbyte of RAM for data, in various segments, and 386 kbyte of Flash memory, ADC, UART, GPIO and so on
    2. As a Bluetooth LE capable microcontroller
    3. For audio and digital signal processing (DSP) applications since it has an in-built DSP (this requires Synopsys tools) - shown in green in the block diagram below


    This is the block diagram of what is inside the RSL10 chip at the heart of the dev-board:


    The software development kit (SDK) comes with lots of example code, ranging from just blinking an on-board LED, all the way to Bluetooth LE applications. I tried downloading it and importing an example "Blinky" application:


    That was straightforward!

    Next, I tried compiling the blinky application:


    The last step in the diagram above should execute the code on the dev-board (I don't have the board to try it, but hopefully it should work).


    The information for all this, and the link to the SDK, is available here:

  • I suppose the bigger issue is that in order to take advantage of the Bluetooth 5.0 capabilities, you will need a rather modern smartphone released either last year or this year (roughly speaking) to have support for the highest-throughput, lowest-power-consumption modes. Otherwise, it would probably not differ very much from testing a Bluetooth 4.0 LE chipset.

    EDIT: Perhaps in light of that it might make sense for the RoadTesters to test this unit in conjunction with PAN1762 Bluetooth Evaluation Kit

  • I opened the box. It has the boards that I showed on the page and a USB cable.


    Here's the manual


    Here's how they connect it:



  • I'd like to apply to check how low power I'd be able to program the device - and how long I would be able to run it on a coin cell battery..

    But doesn't it need an additional piece of hardware - a dongle or receiver that allows you to communicate from a development machine?

    If that's not available one would need to develop a phone app (Android or iPhone) to communicate with it and that's a skill I don't have.

  • I've extended this roadtest because many of the applicants were not quite right for testing this product.


    They did not articulate why this product would help them "bring ultra-low-power Bluetooth Low Energy to wireless applications."

  • I've read through all the applications. I've brought it down from 53 to 14.


    What made these 14 applicants stand out?


    All 14 completed all the questions in a serious way. There were some I didn't select because they answer questions like:


    (d) What is your planned testing procedure (Be as specific as you can)?

    not sure yet


    (c) What interests you about this roadtest?

    every things about it


    (d) What is your planned testing procedure (Be as specific as you can)?

    Would prefer to discuss in person


    I don't consider these answer serious.

    This looks quite interesting. Too bad it did not exist when I participated in the 'Sudden impact' design challenge...
