Re: HCPCA9685 - Library for PCA9685 16ch 12bit PWM controller

I’m assuming you are using the example servo sketch to test your setup? If you’re powering the servo via the module's screw terminal, and it’s convenient to do so could you give the following a try: Could you try connecting the 5V servo supply to either the V+ pin found on the 6 way right-angled he...

Re: HCPCA9685 - Library for PCA9685 16ch 12bit PWM controller

Further to the above, this morning I've measured the voltage on the power pins for various servo plugs and it is a hard 0.00 (normally background voltage on my multimeter is hovering in the low 0.1s). The Arduino is running on the USB to my PC, I'm using a separate 5v supply into the external power ...

Re: HCPCA9685 - Library for PCA9685 16ch 12bit PWM controller

Hi I bought one of these boards this week but I just can't get the example sketch to function. I'm using IDE 2.3.3, a Nano Every and have attached the SCL/SDA to A4/A5 and running a 2IC Scanner I get a response as expected from 0x40 so 2IC communication seems fine. My servo (a standard 9g) is fine (...
