The project is based on the open source project ExpressLRS. It is designed with a complete heat dissipation system for the high-frequency head module for model aircraft to ensure stability under high-power and long-term operation. It is slightly difficult to solder using the smallest component package of 0402. Novices should try it with caution.
Maximum RF power 1000mw
The power chip supports up to 28v input and 3A output.
If there is a serial port chip but no one-key download circuit, you need to hold down the boot key when downloading the program.
