"""IoT curtain crawler, drives a motor and has hall sensors integrated on the board, next to the motor.
Motor: LS16PQQ-030 -183.5

~2.7v min starting voltage; 40mA open current, 200mA stall current @ 4.0v, ~500mA @ 10v

Note, motor driver appears to be fed off a booster, a chip labeled B6283y, which may be a SDB628 booster
with a feedback voltage of 0.6v. Feedback resistor divider produces 121.4mV for a 2.000V input, a ~10v target.

Motor is a 2-pin PicoBlade 1.25mm connector, Molex_PicoBlade_53398-0271_1x02-1MP_P1.25mm_Vertical
