A Micro-format ExpressLRS 2.4 GHz transmitter module with up to 1 W power, a display and active cooling.
The module installs into radios with a Micro/JR bay and works on the open ExpressLRS protocol with output power up to 1 W and packet rates from 25 to 500 Hz. The built-in fan removes heat from the final stage during long operation at high power.
The display lets you change the packet rate or power without connecting to a computer. The antenna connects via SMA-female, and the XT30 connector allows external power (5–12 V) so the radio's battery is not loaded at high power.
Key Advantages
- ExpressLRS 2.4 GHz, up to 1 W
- Packet rate 25–500 Hz
- Display for settings
- Active fan cooling
- External power via XT30
