Operating mode: Pulse-width modulation (PWM)

Properties
The pulse-width modulation (PWM) mode of the compact CPU has the following technical
properties:
Standard output
Pulse duration 100 µs with load >
0.1 A
200 µs with load
≥ 2m A
Period duration 10 ms
A lower value is theoretically possible but, depending on the connected load, the output voltage can no longer be output
