1.Quality description:

• PCB design software: LCEDA ( lceda.cn )
• Component supplier: Lichuang Mall ( szlcsc.com )
• Circuit board manufacturer: Shenzhen Jialichuang ( sz-jlc.com )

2.Module introduction:

This module is the HK32F103VET6 functional development board. Make modifications on the STM32F103VET6 of the original technology team. The functions of the HK32F103VET6 development board are as follows: It also leads out all GPIO ports of the MCU (except PC14 and PC15) to facilitate users to connect other peripheral modules.

1. Using AMS1117 linear voltage regulator chip to convert 5V to 3.3V
2. 1 mini USB interface, 1 USB interface. USB to TTL circuit, using 74HC1G66GW, supports one-click download via serial port (will be changed to Type-C interface later)
3. 2.4 TFT-LCD color screen interface, use your existing TFT color screen , (but found that the direction of the interface female header is reversed and needs to be modified)
4. 0.96 OLED interface, using 7pin, simulates SPI or I2C.
5. NRF24L01 module interface
6. Onboard TF card holder.
7. Onboard ESP8266 module or connected to Tuya module
8. 4 WS2812 colored lights, 1 RGB lamp bead, two 0805LED indicators
9. 4pin female header connected to SHT30 temperature and humidity module header
10. 7525 patch buzzer circuit
11. EEPROM memory chip-AT24C02
12. Onboard FLASH chip-W25Q128
13. Add 4 touch buttons and 1 touch button
14. JTAG standard interface and SWD interface
15. Onboard MPU6050   three-axis accelerometer and three-axis gyroscope, working voltage: 2.375V~3.46V

6. Product physical picture

The onboard MPU6050   three-axis accelerometer and three-axis gyroscope have not been welded yet, and will be welded during subsequent debugging.

7. Development board verification

• 1. USB to serial port download supports one-click serial port download (will be changed to Type-C interface later). The following is a 7-pin OLED as a demonstration. Due to the recent skyrocketing price of chips, I bought a piece of Hangshun HK32F103VET6 (38 yuan) on Taobao.
• Since I am still a junior scholar in the field of programming and only know a little bit, I have made a few simple demonstration examples below.

• 2. Onboard LED indicator and RGB and WS2812 verification.

8.Problem description

• 1. Due to a problem with the 2.2 color screen rows, the rows are reversed from the original pin rows, so they can only be connected in reverse. Other programs have not had time to debug, and we are waiting for subsequent versions to debug.
• 2. The silk screen was written incorrectly. The silk screen in the picture should have been HK32F103VET6, but it was made STM when I wrote it. I'm sorry. The PCB has been modified.
• 3. The development board has many functions, but they have not been verified one by one. We will update them when we have time.
• 4. I also hope that everyone can correct the errors in it and we can modify it together in the future.
