A Micro-format EMAX Aeris Link Micro transmitter module for the 915 MHz band: ExpressLRS protocol, power up to 2 W, 1.29″ OLED.
The module installs into a radio's JR compatible bay and works on the open ExpressLRS protocol in the 915 MHz band, which passes through vegetation and terrain better than 2.4 GHz. Output power is up to 2 W, so a built-in fan that switches on when it heats up is provided.
The 1.29″ OLED display lets you change power and packet rate without a computer or Lua scripts. For high power there is an XT30 port for external power (5–12 V), and the antenna connects via SMA, so the stock antenna can be replaced with a directional one.
Key Advantages
- ExpressLRS 915 MHz, power up to 2 W
- 1.29″ OLED for setup without a computer
- Automatic fan
