stc8a development board

This development board has onboard: 1: usb to ttl; V1.0 version will reverse power supply to stc after power off, and the modification method has been found. 2: Automatic download circuit; automatic download is normal, but an error occurs when switching to manual download. The reason has been found. 3: Battery management circuit; serious error, no soldering. 4: TYPE-C and Micro-B power (USB) interface; 5: 64Mbit Flash; 6: RS485; 7: Camera interface; 8: NRF2401 2.4G wireless interface; 9: Bluetooth module interface; 10: 8 RGB lights ; 11: Buzzer; 12: MPU6050; 13: Clock DS1302; 14: Temperature sensor TMP75; 15: Infrared sensor H638T; 16: 8 buttons; 17: 32KB SRAM. The board can switch between 3.3V and 5V power supply modes, and the two power supplies can be switched to connect to other devices. There is a display interface on the board, which can be connected to parallel LCD12864 and parallel LCD1602, I2C interface and SPI interface OLED12864 and other common TFT displays on Taobao, and can be connected to the 2.8-inch touch TFT (expanded TF card slot) made by myself. With this development board, you can experience the freedom and speed of 32KRAM without being limited by the 8KRAM capacity of the microcontroller. The onboard 8MFlash can store a lot of data, and you can even load it with the FAT file system. With the 2.8-inch display, MPU6050 and various peripherals such as buttons, can't it be developed into a game console or remote control? Develop your imagination, exercise your abilities, and enter the world of wireless and color.
