OddityRC PM90 DC Power Meter & Data Logger

Manual, Software & Firmware: Please contact customer services to obtain！ Portable DC Power Meter — 6–85 V, 90 A, XT60 A compact DC power meter for RC aircraft, UAVs, robots, and power-system testing. Built around the Texas Instruments INA228, it measures voltage, bidirectional current, power, energy (Wh), and charge (Ah), with a color LCD for real-time monitoring. Key Features • 6–85 V DC measurement range with rated current up to 90 A. • Bidirectional current sensing for monitoring charging and discharging. • 128 MB onboard storage for approximately 6 hours of recording at the maximum 166 Hz rate. • USB connection for PC monitoring, graphing, CSV export, and recorded-data playback. • Selectable 40 A and 90 A ranges, with adjustable conversion time and averaging. • XT60 input/output connectors. • Compact dimensions: 60.0 × 42.4 × 20.0 mm, including buttons and connectors. Firmware V1.4.0 adds separate forward/reverse Ah and Wh accumulation, current calibration compensation, and screen rotation. Firmware V1.4.x requires PC software V1.3.0; V1.3.x requires PC software V1.2.0. Operating Note No overvoltage, overcurrent, or reverse-polarity protection is built in. Observe voltage and current ratings, verify polarity, and monitor temperature during use. Fit & setup notesCheck supply voltage, wiring, mounting space and flight-controller or host support for the exact sensor. Confirm the required protocol before connecting it.
