ExpressLRS 2.4GHz PWM Vario Receiver, R24-P6V

The R24-P6V ExpressLRS 2.4GHz PWM receiver is a high-performance, long-range receiver designed for fixed-wing aircraft, RC planes, and UAVs. Featuring the ESP32-PICO-D4 processor and SX1281 RF chipset, it provides low-latency, high-precision control with a 6-channel PWM output. The integrated SPL06-001 barometer enables accurate altitude sensing, making it ideal for gliders and telemetry applications.

This receiver supports antenna-switching diversity for enhanced signal reliability, while its 180mW telemetry power ensures extended control range. With an input voltage range of 4-13V and VBAT voltage sensing up to 25.5V, the R24-P6V is versatile and compatible with various RC setups. It comes preloaded with ExpressLRS 3.3.2 firmware and supports WiFi and UART flashing for easy updates. The RGB LED indicators provide real-time status feedback, ensuring seamless operation.

    Receiver Target:  Generic ESP32 PWM Vario 2.4Ghz RX, /or RadioMaster ER6-GV, /or RadioMaster ER6-G
    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 30s, 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(PWM 2 pin) on receiver connected to the Rx on the USB-TTL, and RX(PWM 3 pin) 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.
    In configurator,  Select the target Generic ESP32 PWM Vario 2.4Ghz RX,  or RadioMaster ER6-GV  and  “UART” for Flashing Method,  set your bind phrase and Firmware Options , Check “erase before flash” and “Force Flash “.
