STM32 development version (verified)

1. You need to bring your own ST-LINGKI downloader, 0.96-inch display screen, and ch340c serial port module.
2. The startup options are not marked. The upper 1 is BOOT0, the lower one is BOOT1, the left short circuit is 1, and the right short circuit is 0. You can check the PCB diagram by yourself.
3. The main control chip is STM32FFF103C8T6.
4. Contains (8-channel button module) (8-channel LED module) (WS2812B lantern module) (MPU6050 gyroscope module)
(Buzzer) (ADC) (DS18B20 temperature sensor) (DHT11 temperature and humidity) (W25Q64 memory) ( Infrared transceiver)
(encoder module) (photoelectric module) (servo drive module).
5. Each module is divided by lines, and each interface is marked with corresponding characters. If you encounter circuit wiring problems, you can check the circuit principle.
6. Some devices test the soldering ability. Weld the SMD device first, and then solder the plug-in after testing that there is no short circuit or virtual soldering. (After welding the plug-in, it is difficult to re-solder the SMT device without a hot air gun.)
Poor welding will cause some devices to not work properly. (Pay special attention to MPU6050) All modules have been verified and can be used normally. If the circuit is not working properly, please check whether there are any weak or missing soldering.
7. The cost of replicating is about 90 yuan.
8. Attached is a 3D printing model file in STL format of the shell. Please pick it up as needed.
