A diy high performance Transmitter Module with ELRS support and custom hardware which can transmit data using Sx1280 RF module and ESP-32. This Transmitter module works on a open source Firmware called ELRS ,which is used in high end transmitters and recievers
- 15km + range (LOS)
- 5ms latency
- Oled and RGB
- External Antenna
- ELRS support
- Custom case and Pcb
- Works on Uart
- Works with any ELRS reciever
- I made this transmitter module for my future projects in which they need a device to transfer data wirelessly , for long range and quickly ,So i made this transmitter module,So I can just send data to this module via Uart and receive on other side using any ELRS reciever.
