Product overview A flight power/telemetry module with an independent on-board sensor power supply, battery voltage outputs via SH1.02P, and multiple PWM and serial interfaces for flexible integration into multirotor and RC systems. Key benefits — why you need it More stable flight: the on-board sensing independent power supply provides dedicated, noise-isolated power for sensors, reducing voltage-related sensor errors and improving flight stability. Flexible telemetry and power distribution: battery voltage outputs on the SH1.02P interface provide direct-port power and telemetry to compatible devices, while supporting up to 6S battery input. Expandable I/O: a large set of PWM outputs and serial connections lets you connect many servos, ESCs, or peripherals without extra converters or wiring changes. Clear ammeter option: while an analog ammeter is not built in, you can add an external I2C-protocol ammeter for precise current/consumption telemetry. What it does (functions) On-board sensing independent power supply: supplies sensors separately from main power, improving signal reliability and flight performance. Battery voltages output via SH1.02P interface: provides battery voltage telemetry and direct-port power for connected modules; supports up to 6S input. 77PWM output: high-count PWM output capability for servos/ESCs and other PWM-driven devices. 3.5 serial port: available serial connectivity for telemetry, control, or receiver links. Note: SBUS can only be counted as half of a serialized interface (SBUS uses a combined line that affects serial-port availability). Compatibility and integration External ammeter: Does not include an analog ammeter; compatible with external ammeters using the I2C protocol. SH1.02P interface: Provides battery voltage signals and direct port power through this connector; ensure mating connector and wiring match SH1.02P specifications. Serial and PWM interfaces: Use the 3.5 serial port and the PWM outputs to connect flight controllers, receivers, or peripherals. Account for SBUS behavior when planning serial-port usage. Performance and limits Maximum battery input: supports up to 6S. Sensor power isolation: independent supply reduces electrical noise that can affect onboard sensors and flight control stability. External ammeter support: use an I2C ammeter for current telemetry since there is no built-in analog ammeter. Typical applications Multirotor drones: power stable sensor operation and supply battery-voltage telemetry to the flight controller while driving many servos or ESCs. RC aircraft with many servos: provide multiple PWM outputs and reliable sensor power when using higher-count control surfaces. Custom UAV/robot projects: integrate battery-voltage outputs and serial telemetry into compact power-distribution and control systems; add an I2C ammeter for current monitoring. What to check before installation Confirm your peripherals support SH1.02P connectors or prepare a compatible wiring adapter. If you need current sensing, select an I2C-compatible external ammeter. Account for SBUS occupying half of a serial interface when assigning serial devices to the 3.5 serial port. Specifications summary On-board sensing independent power supply — improves sensor stability and flight performance. No built-in analog ammeter — supports external I2C ammeters. Battery voltages output via SH1.02P interface; direct port power; max 6S input. 77PWM output; 3.5 serial port (SBUS counts as half a serialized interface). This module is intended for integration into flight systems where stable sensor power, battery telemetry, and a high number of PWM/serial connections are required.
