Happymodel ExpressLRS ES915TX 915MHz Long Range Module and ES915RX Receiver for Radiomaster TX16S Jumper T12 T16 T18 Transmitter

ES915TX and ES915RX modules are a set of long-distance 915mhz 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.

ES915TX：

Dimension: 55mm*39mm*13mm(include heat sink)

Weight: 23gram (exclude antenna)

Antenna connector: SMA

VCC input: 5~13v, Recommend 5v~9v
RF Frequency Range: 902MHz ~ 928MHz
Maximum Output Power: <33dBm(For >27dBm operation, we recommend add a fan for force cooling)

Bind procedure:

1. Supply power to the ES915RX, wait until the red and green LEDs on the ES915RX are off, immediately turn off the power, and then repeat again the above steps. When the ES915RX is powered on for the third time, the red LED light will start to flash quickly, which means that the ES915RX enters the binding mode

2. Insert the ES915TX module to Radio transmitter, and choose External RF mode to CRSF protocol, then you can find ELRS menu from the Radio systems, Enter into ELRS and press [Bind], the Red and Green LEDS on the ES915RX module will getting to be solid if bind successfully.
