ExpressLRS Combo: ES900TX Module + ES900RX Receiver, 868/915MHz, Long Range

This ES900TX + ES900RX combo is a masterpiece of long-range communication: a powerful transmitter pumping close to 33 dBm in the 868/915 MHz band, paired with a nano receiver that weighs less than a gram—beauty and performance combined.

The ES900TX module features a heatsink and active cooling (fan activates above 27 dBm), delivering ultra-stable high-power output for epic-range flights.

On the receiving end, the ES900RX is an exemplar of miniaturization: a sleek 0.6 g body with IPEX antenna interface, support for CRSF protocol, and up to 17 dBm telemetry power—perfect for micro and lightweight setups.

Together, they form more than a kit—they're your trusted link to everything beyond the horizon, with reliability that never fails.
