ELRS 900MHz VTX EMAX Link ExpressLRS Micro TX Module

FEATURES

• Frequency Band: (900MHz version/720-1020Mhz optional)
• Output power: 100mW/250mW/500mW/1000mW/(2000mW optional)
• Refresh rate: 25Hz/50Hz/100Hz/200Hz
• Input Voltage: 5-12V(2S)
• Main control IC: ESP32+SX1276, backpack chip ESP8285
• By default, the ELRS-900-TX high-frequency head only accepts signals from the Crossfire Serial Data Protocol (CRSF). The high-frequency head interface of the remote control needs to support CRSF signal output. The following takes the OpenTX remote control system as an example to illustrate how to configure the remote control to output CRSF signals and use the LUA script to control the ELRS high-frequency head。
