These modules are characterized by ultra long distance, stable operation, and low latency. The module is compatible with the vast majority of Opentx remote controls, especially suitable for the Radiomaster TX16S and Jumper T12 T16 T18 series remote controls, which are basically plug and play. We have specially customized a cooling module for the transmission module and added a 2006 cooling fan for the new version of ES900TX, which can help the transmission module operate stably under high power conditions. The fan is plug and play, and automatically operates when the transmission module power is set to 250mw. The receiver module is very small and mini, weighing only 0.6g without an antenna, making it very suitable for various types of Whoop traversing machines and Toothpick toothpick machines to be used together. Both the high-frequency head module and receiver module can be selected from 915MHz or 868MHz, and we have already programmed and tested them before leaving the factory. Frequency alignment steps for the new ES900RX receiver: 1. Power up the ES900RX receiver, turn off the power immediately after the LED on the receiver goes out, and then repeat it again. After supplying power to the ES900RX for the third time, the LED lights on the receiver will start to double flash, indicating that the ES900RX receiver has entered frequency synchronization mode. 2. Connect the ES900TX or ES915TX high-frequency head module, select the CRSF protocol in the remote control module options, then find the ELRS option, enter and select BIND. After successful frequency matching, the LED light on the receiver will first turn off, then slowly flash and then remain on. - JR Standard High Frequency Head Shell 3D Print Download Address http://dwz.win/afah - Debugging software download address https://github.com/ExpressLRS/ExpressLRS-Configurator/releases - Program Release Page https://github.com/ExpressLRS/ExpressLRS/releases Package Included: - The new ES900TX and ES900RX packages include: - ES900 TX module high-frequency head module x1 (915MHz or 868MHz optional) - ES900 TX high frequency head housing x1 - ES900 RX module receiver module x1 (915MHz or 868MHz optional) - TX antenna x1 high frequency head antenna x1 - RX antenna x2 receiver antenna x2 - Heat sink x1 - 2006 Fan x1 Cooling Fan x1 - Adapter wire x1 Buying a high-frequency head separately includes: - ES900 TX module high-frequency head module x1 (915MHz or 868MHz optional) - ES900 TX high frequency head housing x1 - TX antenna x1 high frequency head antenna x1 - Adapter wire x1 - Heat sink x1 - 2006 Fan x1 Cooling Fan x1 Purchasing the receiver module separately includes: - ES900 RX module receiver module x1 (915MHz or 868MHz optional) - RX antenna x2 receiver antenna x2
