Happymodel ExpressLRS ELRS EPW6 PWM is a lightweight and compact PWM receiver for efficient remote control of FPV drones! It provides a reliable connection and stable operation in the 2.4GHz (2400~2480MHz) operating frequency range. Designed with ESP8285 and SX1280/1281 chips, ensuring high data transfer speed and signal quality. A special feature of the receiver is the presence of 6 PWM outputs, allowing control of six channels. Telemetry power up to 12dBm ensures data transmission over sufficiently long distances. The receiver supports two protocols: PWM and CRSF, allowing it to be used in various configurations. ELRS has two firmware options: Standard ESP8285 6xPWM 2.4GHz RX and HappyModel_EP_2400_RX, which can be updated via WIFI.

Recommendations

How to enable CRSF serial output:

• 1. First, enable Wi-Fi for the receiver
• 2. Visit http://10.0.0.1/hardware.html
• 3. Remove «pin 1» and «pin 3» from the PWM output

• 4. Add pin 3 and pin 1 to the CRSF serial pins
