Perfect for faking a PC fan rpm signal
Used this to fake a high RPM signal in a server that wasn't happy with Noctua fan replacement spinning at less than half the OEM Delta fan speed. Worked a charm, machine is now quiet. Connected the 12v, ground and rpm wires via a splitter from the fan header to this board, with 12v+ground+pwm going to the fan.

Hoping to use these to learn my oscilloscope functions...and invent stuff

Exactement ce que je cherche

The way the circuit it setup, the charge and discharge paths are connected and duty cycles below 50% or above 80% aren't stable or aren't possible. Not a good solution if you need a typical and linear duty cycle range

Fonctionne, mais le réglage du "Duty Cycle" n'est absolument pas précis et interfère beaucoup trop sur la fréquence

Article correct pour un prix modéré. Fonctionne bien, pas de surprise
