The ES900TX module is a long-distance 915mhz wireless transmission developed and designed based on the ExpressLRS open-source software. The ES900TX is characterized by ultra-long-range, stable operation, and low latency. This module is compatible with most Opentx remote controllers, especially suitable for Radiomaster TX16S and Jumper T12, T16, and T18 series remote controllers – basically plug and play. The heat sink has been specially customized for the transmitter module, which can help the transmitter to operate stably under high-power conditions.
Note: Radio and RX Not Included
