I have an aluminium project box containing a 3.2, W5500 board, 1602 i2c display and rotary breakout which is itermittently freaking out when (the rotary encoder is) touched. First i was looking at my sketch and have been letting it sit for timed intervals before moving the rotary, but the last time it scrambled was on initial touch and i heard a small pop in my speakers leading me to suspect a static discharge.
This box is usb powered but i want to make an externally powered version with buck converter taking 12V input down to 5V. I understood having a 100uF and 10nF capaciter on the buck converter input and output could help?
Are there any basic precautions i can take circuit wise to protect the system from static?
