BetaFPV SuperP 14CH 2.4GHz Diversity Receiver

The BetaFPV SuperP 14CH is a 2.4GHz ExpressLRS true diversity receiver built for fixed-wing aircraft and other builds that need more than a simple quad receiver. Its 14 PWM outputs let it double as a servo controller, cutting the need for a separate flight controller on simple planes and RC vehicles.

Key features

• True diversity design with two independent SX1280/SX1281 RF chains and dual U.FL antennas for stronger link reliability.
• 14 direct PWM outputs, enough to drive servos, flaps, gimbals and auxiliary payloads without a flight controller.
• Shared TCXO oscillator keeps both RF chains on an accurate, temperature-stable clock for long-range flights.
• I2C port for an external barometer and a 3-pin port for an RGB light strip.
• ESP32 Pico D4 core with built-in Wi-Fi for over-the-air ExpressLRS configuration and firmware updates via USB-C.

Specifications

• MCU: ESP32 Pico D4 + 2x SX1280/SX1281
• Frequency: 2.4GHz ISM
• Telemetry power: 100mW (20dBm)
• PWM channels: 14
• Output protocol: PWM, CRSF or SBUS
• Input voltage: 3.5-8.4V DC (1-2S)
• Antenna: 2x U.FL
• Dimensions: 46.9 x 32.7 x 14.6mm
• Weight: 15.5g

Mount the two antennas vertically and apart from each other for the best diversity performance; the receiver will run from anywhere in its 3.5-8.4V range, including a 2S pack, an FC rail or a BEC.
