Battery voltages output (SH1.02P interfaced) battery voltages at the same timing for the clear map transmission direct port power supply, the 6s input. Not with analog ammeter function (can be external I2C protocol ammeter). 77PWM output, 3.5 serialized port (SBUS can only count as half a serialized port). Onboard sensing with independent power supply, more stable flight. Use scenarios Mapping and data transmission drones: The synchronized battery voltage output supports a clean power supply for map transmission gear and direct port devices, with compatibility for up to 6S packs, helping maintain stable data communication during flights. FPV and telemetry setups: The 77PWM output and 3.5 serialized port with SBUS compatibility enable efficient control and telemetry routing, while SBUS is counted as half a serialized port when needed. Flight stability emphasis: Independent power supply for onboard sensing reduces power noise, contributing to more stable flight characteristics in sensitive sensor configurations. Key attributes Function: Synchronized battery voltage output with SH1.02P interface; direct port power supply; supports up to 6S input. Compatibility: SH1.02P interfaced system; PWM output and serialized port options suitable for common flight controllers and sensor gear; SBUS support with port counting consideration. Performance: Independent onboard sensing power supply for improved stability; designed to minimize timing and powerrelated issues during flight.
