Sensor connector pinout

A project log for RUDDOG RP691 2200kV characterization

Since datasheet for this BLDC motor is not available, I will try to characterize its properties and share it here.

Pin 1: Supply voltage (both 3V3 and 5V tolerant).

Pin 2: NTC thermistor output (with respect to GND). 10kOhm @ 25 °C; Beta unknown for now.

Pin 3: Hall 1 output. Open drain. Seems to be related to Phase A.

Pin 4: Hall 2 output. Open drain. Seems to be related to Phase B.

Pin 5: Hall 3 output. Open drain. Seems to be related to Phase C.

Pin 6: Common ground.
