Based on AirF103, HeZhou Daplink

Overview

To resolve the lack of 5V power supply in the official DAP from Heze Technology, the pins are adapted to the development board from Fanke Technology, allowing for direct plug-in connection (requiring disconnecting the 0-ohm resistor connected to the 3.3V pin on the back). Bring out boot0, use ISP download, TX and RX correspond to PA9 and PA10 on the back
, consistent with the STM32 ISP download method. After using an ISP download tool (FlyMcu, etc.) to burn the daplink_v2.hex firmware, connect to the computer via Type-C to check if it is recognized correctly. Disconnect, short-circuit RST and GND, then connect to the computer. A pop-up window will appear; disconnect RST and GND, select Firmware 1 or Firmware 2 and drag and drop to burn. (Firmware 1 is the official V2 version upgrade firmware; Firmware 2 removes the USB flash drive function and network pop-up).
For detailed usage and upgrade methods, please refer to the Heze official website DAPLink User Manual - LuatOS document.
