Battery voltage output via SH1.02P interface provides synchronized battery voltages for the direct port power supply used in map transmission, supporting up to 6S input. Suitable for small and miniature fixed wing aircraft such as F80, microed clawed, hand thrower, and Arwing. PWM output and a 3.5 serial port, with SBUS counted as half a serial port. Can be directly inserted into the ELRS receiver, resulting in a smaller overall size. Use scenarios Scenario 1: In a compact fixed wing build, install this module to deliver synchronized battery voltage to the flight controller and ELRS while powering the map transmission direct port, helping maintain stable power during flight. Scenario 2: For a micro hand thrower or small Arwing, use this unit to supply consistent voltage to the receiver and servos with minimal wiring and reduced overall size. Scenario 3: Upgrade a tiny FPV setup by plugging directly into the ELRS receiver, achieving a smaller, lighter configuration without compromising voltage delivery or communication support.
