Happymodel ExpressLRS module ES915TX/ES915RX Long range ELRS hardware 915mhz/868mhz support


ES915TX and ES915RX modules are a set of long-distance 915mhz/868mhz(optional) wireless transmission equipment developed and designed based on the open source software ExpressLRS. This set of modules is characterized by ultra-long range, stable operation and low latency. The module is compatible with most Opentx remote controllers, especially suitable for Radiomaster TX16S and Jumper T12 T16 T18 series remote controllers, basically plug and play. We have specially customized the heat sink for the transmitter module, which can help the transmitter module to operate stably under high power conditions.
