Hello,
Wanted to check if anybody has similar problems with their Ergodox Infinity. From yesterday one half of keyboard goes into boot loop and chip U1 on PCB gets very hot. I believe this has happened because static electricity and no proper grounding/protection on the keyboard itself. Very sad.
Thanks, Rasmus

rasmusxYou would not be the first one to have the microcontroller get fried by stray electrons. And yes, there is no grounding of the plate so the electrons go through the plate and then the switches to find ground. A cell phone repair shop may be able to solder in a new chip. About $16 plus shipping for the chip.

rasmusxThanks for your info. I think adding an small EMI foam gasket between the USB connector and plate on each side of the keyboard will prevent the damage caused by ESD. It's time to find a seller and get all my keyboards modified:)

riverprawnHi, sorry for the necro. I was wondering if you went ahead with your EMI foam fix. I‘m quite new to this stuff so thought I would ask for some help.. :) Got some «antistatic foam» from an electronics shop, is it the right type?
Also, how would you cut and place the foam? Both between the USB-C and -A connectors and the plate?
