Adafruit feathers and sound boards not working

by fubar_labs on Mon Nov 13, 2017 1:49 am

I tried connecting a adafruit feather proto (https://www.adafruit.com/product/2771) and Adafruit Sound Fx board (https://www.adafruit.com/product/2220) and adafruit Class D amp (https://www.adafruit.com/product/2130) in a circuit i have done 50 times before and the boards don't functions. I know the code works because i tested on another feather/sound board/amp circuit and it works. I'm guessing the boards are faulty or pins are faulty. I have two feathers and 3 sound boards with amps. I would like replacements please. Thank you for your time and effort. You guys make awesome products and have awesome tech support. I know sometimes boards come out bad, but i look forward to buying more of these in the future.

Which of the three products do you think has the issue? Can you get a simple blink sketch to run on the Feather? Can you get anything to play on the sound FX board if you trigger manually? Can you supply the amp with a known good audio signal and see if it works?

The blink sketch works on the feathers, but several of the pins no longer register high when i blink them.

The sound board doesn't respond to TX/RX commands and when i disconnect the UG pin from ground the trigger pins don't activate the uploaded sounds.

I didn't de-solder the amps from the sound board yet, cause i didn't want to damage it or the sound board anymore.

I believe the pins don't have any connectivity in them.

Post a photo of your setup showing how all these items are wired up and connected together.

Did you test them separately before attaching them together?

I tested each part using the blink sketch and they all worked. The sound board i tested by hand by touching ground to one of the trigger pins before i connected UG pin to ground and they all worked.

So it sounds like everything worked as expected before you started assembling everything and wiring the boards together. It also looks like there are things that were soldered on and then removed. Carefully go over every thing and see if you can find any shorts or wiring issues.

The sound boards were connected to the feathers. The feathers had rotary encoder and led backpacks and the sound boards. After i removed everything i tested each pin on the feather and the pins no longer read high when i set them high. The sound boards don't work in UART mode and in trigger mode after de-soldering the UG pin.

Even pin 13? That's tied to the red LED that is driven by the blink sketch. So I'm not sure how the blink sketch could still work but you would not see the voltage change on that pin.

All the Digital IO pins i was using didn't read high, pin 13 still worked and the led blinked on and off along with 3v and gnd and Vbat

Are the pins that no longer work the same ones you soldered stuff to?
