Hello everyone, I am very excited to start my blog series with Minized Board unboxing and general overview.
Unboxing:
Alright, here's the Minized board and it arrived in a neatly packaged box. The box features a sleek design. Inside the box, we can see the board securely packed with foam to ensure its safety during transit.
Package Contents:
After opening the box, we had a quick start guide. It's always good to have clear instructions to get started with the board. I am just going to follow it in the following sections. Next, we have the Minized board itself, nicely wrapped in an antistatic bag. I carefully took it out and then we had a USB to JTAG/UART cable which is also quite useful.
Board Overview:
Now that we have the Minized board out of the antistatic bag let's get a closer look at it. The board is incredibly compact, which is perfect for prototyping and embedded projects. On the top side, we can see various connectors and components. Here, we have the Xilinx Zynq 7Z007S SoC, which combines an FPGA and a dual-core Arm Cortex-A9 processor.
Moving on, we have a USB host port with a USB phy chip, a USB JTAG/UART port for power and com port functionality, and another Micro USB port for auxillary power. There are also user LEDs, a reset button, and a power indicator LED. Additionally, we have DDR3L, emmc, QSPI flash based memory. We also have WIFI and bluetooth connectivity options. This is my first board that has such wireless connectivity options. There are also a Accelerometer and temperature sensors. There is also an on-board microphone.
Connecting UART cable and starting the board
I have connected the UART cable and the board just powered immediately. So that was simple.
Below I have captured the boot log on the UART terminal observed in my terminal. As expected, the device is booting from the on-board QSPI flash. I followed the instruction provided in the instruction manual. I logged in with the username and password provided in the manual.

i was able to pair the bluetooth with my phone
This definitely confirms that the bluetooth is working and I can pair with it.
Testing Temperature and Motion sensor:
I also verified that I can read the temperature values from the on-board temperature sensor and the motion sensor also responded to movement and tilting of the board.

Testing the Microphone and its impact on PL User LED (D8):
This is a nice demostration. I was able to whistle near the Microphone and observe the colour of the PL User LED (D8) change from non to Green to Red based on the intensity of the sound.
Conclusion:
In conclusion, the Minized board looks like a powerful and versatile development platform, perfect for a wide range of applications because of the availability of the various wireless interfaces. The compact size, combined with the FPGA capabilities, makes it a fantastic choice for anyone interested in FPGA and embedded development.
I am excited to start experimenting with this board and sharing my projects with all of you. Keep exploring.
