The ES24TX Slim Pro TX module is designed by Happymodel and based on the open source ExpressLRS project, which is an affordable, low latency, long range RC system developed for FPV racing drones and other RC applications.
Being an open source project, it’s possible to build a ExpressLRS RF module from scratch, but Happymodel have saved you the effort with this complete module. It comes pre-loaded with the ExpressLRS firmware and its plug and play for Frsky X-lite/X-lite pro/X9 Lite & TBS Tango2 radios.
Its main hardware architecture uses the ESP32, ESP8285 and SX1280 RF chips. It comes housed in an aluminium alloy shell and is equipped with a cooling fan that automatically works when the module is working at 250mw. The TX module supports a maximum power output of ~1000mw.
Features:
- Supports up to 1000mw RF power (T-lite radio and Tango2 radio need external power supply)
- RGB LED ready
- Cooling Fan ready
- Open source ExpressLRS
- Long range, low latency and high re-flashed rates
- Telemetry data transmission supported
- CNC aluminium protective shell
