External analog ammeter is not included; you may use an external I2C protocol electronic meter for current measurement. This offers flexibility to choose your preferred meter while keeping the device compact. Battery voltage output via the SH1.02p interface provides a direct, mapped battery voltage readout. It enables a direct port power supply with synchronized timing for up to 6S input, helping to power connected components while maintaining voltage visibility. Plugs directly into an ELRS receiver for simple and straightforward integration, reducing wiring complexity and setup time. PWM and serial interfaces included: a 77PWM output and a 3.5 serial port (SBUS can only count as half of the serial port). This provides versatile control and telemetry options for compatible flight controllers and accessories. Key benefits Flexible measurement setup: choose your own external ammeter to suit required accuracy and form factor, without tying you to a builtin meter. Integrated voltage monitoring and power delivery: battery voltage is available via a dedicated interface with timing aligned to the system, suitable for up to 6S packs, enabling reliable power distribution and monitoring. Simple ELRS compatibility: direct plug into ELRS receivers reduces wiring and simplifies installation in compatible RC systems. Multiple I/O options for telemetry and control: PWM and serial interfaces enable practical integration with flight controllers, ESCs, and telemetry modules. Use scenarios ELRSenabled drone or RC aircraft up to 6S: plug into the receiver, monitor battery voltage through the SH1.02p interface, and power auxiliary components with synchronized timing, while using external ammeter as needed. RC plane or quad with telemetry needs: utilize the PWM output and serial port for control signals and data transmission, with SBUS compatibility noted. Bench testing or hobbyist experiments: connect to an external I2C ammeter for current measurements while using the PWM and serial outputs to simulate or test subsystems.
