e
From a thermistor
device mounted inside
the motor
V = 5 V
(via 2.2 kΩ
internal pull-
up resistor)
A NTC thermistor having a
resistance of approximately
2.2 kΩ at 100°C will give
best sensitivity.
Connect the other lead of
the thermistor to the B-
terminal of the Gen4
controller.
Can also be used as an
additional analogue input
