Product overview
The Rctimer 3DR APM Pixhawk Voltage & Current Sensor 90A W/ Amass XT60 Kit, code VIS-XT60, provides DC voltage and current sensing for flight controller integration. Its 15x17mm board combines INA-169 measurement conversion with a precision resistor divider for voltage sensing. The analog output is scaled for a 3.3V ADC, and the board is self powered with very low zero current offset. AIOP and APM are named applications; APM configuration uses the AttoPilot 50V 90A setting in Mission Planner.
The hardware voltage and current maxima are 51.8V and 89.4A, while the input specification separately states 2-6S (MAX 28V). The BEC rating is 5.3V / 3A. Supplied equipment comprises one voltage and current sensor and one 150mm UART 3Pin cable; the PCB itself comes without leads or connectors. Connection pads accept 12 gauge heavy duty leads, but assembly requires careful soldering. Using smaller gauge leads eases the soldering work and helps avoid shorts during connection.
