π§ͺ Typical Uses
-
Generate square/PWM signals for dev & lab work
-
Speed control via motor drivers, servo/stepper interfaces
-
MCU input testing, timer/counter evaluation
-
PWM dimming experiments and circuit tuning
π§ Quick Start
-
Power with 3.3β30 V DC (observe polarity).
-
Press ON/OFF to enable the output.
-
Turn the FREQ encoder to set frequency; turn the DUTY encoder to set duty.
-
Hold the lock to prevent accidental changes; switch Normal/Fine for desired resolution.
-
For serial use, connect TTL pins per your controller (baud/protocol per module reference).
