ELRS_GEMINI High Frequency Head

I. Operation Process 1. After PCB soldering, first burn the ESP01F firmware, then the ESP32 firmware; 2. There are two shorting pads on the PCB (burning and communication). These are used to burn the ESP01F firmware. Shorting the "burning" pad will burn the firmware (press and hold the second boot button while powering on), and shorting the "communication" pad will communicate with the ESP32 firmware; 3. You can burn the ESP32 firmware by powering on without shorting any pads; 2. There are many burning methods. Here are a few recommended: 1# Use the official tool flash_download_tool (select ESP8285 for ESP01F); 2# Use Visual Studio Code to compile and burn the firmware (this method requires configuring Python packages, which can be complicated); 3# Use ExpressLRS Configurator, but compilation is difficult; 4# Use the ExpressLRS web flasher for online burning via web: https://expresslrs.github.io/web-flasher/ This is easy to use, compiles quickly, and is less difficult; II. IO Configuration 1. After burning the firmware, you also need to configure the pin attributes. 2. Power on and wait for Wi-Fi (WiFi name "ExpressLRSTX") to turn on. Connect to the Wi-Fi and open this website in your browser: http://10.0.0.1/hardware.html. Drag the (ESP32_E28_IO-json) configuration file into the website and save it. That completes the process. You can now use it. ————Good luck! The UFOIO
