ExpressLRS ELRS ES900TX Ultra Long Range Transmitter Module and ES900RX 0.6g Receiver

Please consult Local Telecom regulations when using this item!

ES900TX and ES900RX modules are a set of Long Range 915MHz/868MHz(optional) wireless transmission equipment developed and designed based on the open source software ExpressLRS. This set of modules is characterized by an ultra-long range, stable operation and low latency. The module is compatible with most Opentx remote controls,, basically plug and play. We specially adapted a heat sink for the transmitter module and also reserved the installation position of the 2006 fan, which can help the transmitter module work stably under high power conditions.

New ES900TX module comes with a 2006 fan, it works automatically when the TX power is 250mW.
