MATEK ELRS-R24-P6 ELRS 2.4GHZ PWM RECEIVER
Check out all of our Matek Products!
Introducing the ELRS-R24-P6, a compact and lightweight microcontroller module designed for a wide range of applications. Equipped with the ESP8285 chipset and SX1281 RF chip, this device promises reliable performance in a small package, measuring just 20mm x 18mm and weighing a mere 2g with its antenna. It’s well-suited for projects requiring precise control, offering six PWM outputs and an IPEX MHF 1 antenna connector for dependable signal transmission.
The module is versatile, supporting a broad voltage range from 2S to 8S and functioning within the 2.4GHz RF frequency band. Telemetry data transmission is robust, with a power of 12dbm. The ELRS-R24-P6 is user-friendly, featuring an input voltage range of 4~9V DC and the capacity to sense voltages up to 34V. Despite its diminutive size, it maintains efficiency with modest power dissipation in both binding and Wi-Fi modes.
Each package of the ELRS-R24-P6 includes the main module, a 15cm IPEX MHF1 Antenna, and Dupont 2.54 pins that are shipped unsoldered for customizable installations. Whether for DIY enthusiasts, remote control applications, or bespoke electronic integrations, this module stands out for its blend of compactness, efficiency, and versatility.

Firmware
- ExpressLRS 3.0 or newer, DIY 2.4 GHz / DIY 2400 RX PWMP EX
- ExpressLRS wiki for PWM receiver, Click HERE
- Make sure Receiver and TX module both are running ExpressLRS 3.0 or newer
——————————————————-
- Receiver has ExpressLRS 3.0 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 go into WebUI to set your binding phrase.
Flashing via Wifi
- Disconnect ESC and servos from receiver first.
- Power on receiver by 5V source. Receiver’s LED(Red) will blink slow at first, and after 20s, it should blink fast indicating it’s on Wifi Hotspot Mode.
- More detailed steps, pls refer this page.
- Target:
- configurator 1.5.x or older, DIY 2.4 GHz –> DIY 2400 RX PWMP EX
- configurator 1.6.x or newer, Generic targets used as a base 2.4 GHz –> Generic ESP8285 6xPWM 2.4Ghz RX
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 5V 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.
- configurator 1.5.x or older, Select the target DIY 2.4 GHz / DIY 2400 RX PWMP EX and “UART” for Flashing Method, set your bind phrase and Firmware Options and once done, click on Build and Flash.
- configurator 1.6.x or newer, Select the target Generic targets used as a base 2.4 GHz –> Generic ESP8285 6xPWM 2.4Ghz RX and “UART” for Flashing Method, set your bind phrase and Firmware Options , Check “erase before flash” and “Force FLash “.
- If you use web-flasher https://pkendall64.github.io/elrs-web-flasher/ , select Generic targets used as a base –> 2.4GHz Receiver –> Generic ESP8285 6xPWM 2.4GHz RX, and enable “Erase flash first”.
