SIYI Hall Sensor Power Module (7-100V Wide Voltage)

SIYI's wide-voltage power module feeds a flight controller and reports battery voltage and current, with a matching Hall-effect sensor doing the current measurement in place of a shunt resistor. Its 7-100 V input spans roughly 3S to 22S LiPo, from small multirotors up to high-voltage heavy-lift and agricultural drones.

Key features

• Non-contact Hall current sensing with ±0.1 A precision
• No shunt in the power path, so there is no insertion loss and no error from contact resistance or a poor joint
• Unaffected by inductance, so it tracks high and fast-changing currents accurately
• Voltage detection across the full 7-100 V range
• All-metal CNC housing for heat dissipation in a compact, lightweight package

Specifications

• Input voltage: 7-100 V (about 3S-22S LiPo)
• Voltage detection: 7-100 V
• Current sensing: Hall effect, non-contact
• Current precision: ±0.1 A
• Housing: CNC-machined metal

Check that the module's output connector suits your flight controller's power port, and set the voltage and current calibration in your flight-control firmware after installing it.
