[Physical product verified] Lite version of STM32F103RE development board

Since I found a new job, business trips take up more than half of my time. I want to play with a microcontroller, but I hate that the board is too big and needs a Jlink, which is inconvenient to carry. If it doesn’t work, just make a board with a small jlink built-in:)

Let’s briefly talk about the functions of this development board:

1. The onboard JLINK can be downloaded through SWD mode.

The running lights of the 2.51 development board have been transplanted. At the top of the board, the conventional STM32 only has 3 lights at most. I used 8 here, which is enough for you to enjoy.

3. Infrared, temperature and temperature and humidity are reserved.

4. Most of the RGB lights and speakers that are available on STM32 are also placed together. The speaker jumper is not recommended for daily use.

5. The buttons use a design of 1 reset button + 3 regular buttons + 1 touch button.

6. The IIC and SPI displays use a 7-pin socket and are compatible with common OLED displays currently on the market.

7. If you don’t consider losing the clock due to power failure, you don’t need to weld the battery part on the back, just short it to 3.3V.

8. I have silk-screened all the IO ports used on the board. When developing, you can directly look at the board without looking at the schematic diagram. This is also a benefit given to everyone by me, a lazy person.

9. The most important point is that you only need one TYPEC data cable to use this board, and you no longer need an external programmer:)

10. The JLINK burning program is in my other post: https://oshwhub.com/duyes/ce-shi-jlink-ob-with-cdc-f103cxt6

I wish you all a good time and good learning.
