Matek has made a current sensor for vehicles that do not have a built in current sensor or for those who want to not have any voltage drop or heat build up like can occur with traditional resistor based measuring techniques.

Specifications

Hall effect current sensor
No voltage drop and heat on current sensor components
Offset and Sensitivity are calibrated in factory

Sensitivity: 20mV/A, INAV/BF scale = 200, ArduPilot BATT_AMP_PERVLT = 50
VBAT voltage sense: 0~69V, INAV scale = 2100, BF scale = 210, ArduPilot BATT_VOLT_MULT = 21.0
Power Consumption: 17mA
Voltage offset error at zero current : +-10mV
Curr output voltage error: 5%
Operating Temperatures: -30~80 °C
23 * 20* 23mm, 7g
step file HCS-150A_step.zip

Soldering Pads:

Vbat: for voltage sense, support 0~69V IN
Volt: = 1/21 Vbat, 0~3.3V out
Curr: Current signal, 0~3.3V out
5V: power supply for HCS-150A board, support 4~13V IN, 17mA
G: GND
TX/RX: for firmware update and configure (to be supported)
