* User key KEY (PA0) x 1
* Reset button NRST x 1
* BOOT0 button x 1

Design and Quality:
* Using lead-free soldering process, PCB with gold immersion process
* Set BOOT in the form of buttons
* High-quality crystal oscillator with metal shell can start oscillation well
* Always use original chips for ST

Attention:
* Github/Gitee regularly updates the batch number of chips used to ensure that you are buying brand new chips
* No factory test program is provided to prevent the occurrence of counterfeiting

Size:
* Board size: 52.38mm x 20.78mm

How to enter ISP (serial port/USB download):
Method 1:
* Press BOOT0 and NRST at the same time, release NRST, release BOOT0 after 0.5S, and then it can enter ISP mode

Method 2:
* In power-off state, press and hold BOOT0, power on, wait for 0.5S, release to enter ISP mode
* Serial port download: use USB to serial port to connect PA9 and PA10 of the core board, do not use USB port for power supply
* USB download: Just use a data cable to connect to a computer. If there is an unrecognized problem, you can properly heat the chip (25℃+), and then re-enter the ISP mode
* Software: STM32CubeProg and WeAct Studio Download Tool

WeAct Studio USB Download Tool:
* Hold down the BOOT0 key and connect to a computer
* Device Manager will show DFU devices
* Input the file name of the firmware to be burned. For example, firmware.bin
* Download Addr: 0x08000000

How to enter HID IAP (USB download):
USB to serial port, debugger, and computer driver are not needed. Just use a TYPE-C data cable to download firmware
1. Burn the HID IAP firmware (it is a special test version, for the factory program is flashed by default)
2. Press and hold the KEY button to power on or press and hold the KEY button to reset, LED C13 flashes, release the button to enter
3. Confirm that the APP firmware address is 0x8004000, and the interrupt address offset is 0x4000
4. Download using Soft/WeAct_HID_FW_Bootloader/WeAct_HID_Flash_xxx.exe

Package Included:
* 1 x Board
* 2 x Pin Headers (20-pin 2.54mm)
* 1 x Pin Header (4-pin 2.54mm)
