Yukon Quad Servo Regulated Module

Hi everyone,

I’m currently using the Yukon board to control a factory automation prototype, and I’m running into some issues with the quad servo regulate module.

Servo outputs 1 and 2 are functioning as intended, however I’m not able to actuate any servos through 3 and 4. I’ve checked the voltage of 3 and 4 and I’m getting the expected 7.4V (after cutting the traces at the back).

I’ve experimented with my own code as well as the example code from the documentation: yukon/examples/modules/quad_servo/four_servos.py at main · pimoroni/yukon · GitHub

I was wondering if this had happened to anyone else and if there was any kind of initialisation I’m missing? The code is not throwing any errors and seems to be happy to send position values to servo3 and servo4, but nothing happens. My current next step is to test with another module in case this one is damaged, but that’s really my last idea at this stage.

Thank you for your help!
