Specific for the Gliders and other fixed-wings. Small in form factor, It can be installed in gliders with restricted payload bays such as DLG’s and high performance slopers. Not needing to install an additional altimeter/variometer also saves room and weight.
The built in barometer provides vertical speed telemetry. The variometer sounds both ascending and descending tones, so you will know whether you are in lift or sink without having to look at your transmitter.

with ExpressLRS firmware and CRSF protocol, this will also give you other telemetry data like battery voltage, current and GPS related.

Receiver Target: Generic targets used as a base 2.4 GHz > > Generic ESP32 PWM Vario 2.4Ghz RX
Receiver has ExpressLRS 3.3.2 preloaded with binding phrase “123456”, the Receiver will never enter binding mode if using the traditional binding procedure.
You need to reflash it with your binding phrase OR connect it to your PC/phone via WiFi and set your binding phrase in WebUI.

Tips

Full Resolution Switch Configuration Modes
Powering receiver with Reverse Voltage will damage the regulator chip. DOUBLE CHECK the power wires connected to the receiver.
Transmitter fw version should be EdgeTX 2.7.1/OpenTX 2.3.15 or newer

——————————————————-

Flashing via Wifi

Power on receiver. Receiver’s LED(Red) will blink slow at first, and after 20s, it should blink fast indicating it’s on Wifi Hotspot Mode.
Wifi SSID “ExpressLRS RX”, Password “expresslrs”
More detailed steps, pls refer this page.

Flashing via UART

Disconnect ESC and servos from receiver first.
Wire the receiver into the USB-TTL adapter, with TX on receiver connected to the Rx on the USB-TTL, and RX on receiver connected to the Tx of the USB-TTL. Wire 5V and GND of the USB-TTL to “V” and GND of the Receiver.
Press the boot button while powering on the receiver, then release – the Red LED on receiver should now be solid on.
Configurator 1.6.x or newer, Select the target Generic targets used as a base 2.4 GHz –> Generic ESP32 PWM Vario 2.4Ghz RXX and “UART” for Flashing Method, set your bind phrase and Firmware Options , Check “erase before flash” and “Force FLash “.
