BetaFPV ELRS Micro PWM 5CH Receiver 2.4GHz

The BetaFPV ELRS Micro receiver brings the ExpressLRS 2.4 GHz link to models that need plain servo outputs: fixed-wings, helicopters, RC cars and boats. It drives up to five PWM channels directly, with no flight controller required.

Key features

• Five PWM servo outputs with failsafe support to protect the model on signal loss

• Can be flashed to CRSF serial output (CH2 = TX, CH3 = RX) for use with a flight controller

• 17 mW telemetry back to the radio

• Runs on 5-9 V at the + pad, straight off a BEC or servo rail

• IPEX (U.FL) antenna connector; 4.5 g with antenna

Specifications

• Frequency: 2.4 GHz ISM

• PWM channels: 5

• Output: PWM or CRSF

• Chipset: ESP8285 with SX1280/SX1281

• Telemetry power: 12.5 dBm (17 mW)

• Input voltage: 5-9 V DC

• Antenna: IPEX MHF, 80 mm dipole T antenna recommended

• Default firmware: ExpressLRS 2.0

• Size: 19 x 32 x 9 mm (without antenna)

• Weight: 4.5 g (with antenna)

The receiver ships on ExpressLRS 2.0, so your transmitter module must run the same major version, or you can update both, before they will bind.
