## Note This post will get updated whenever we have done a new mod ## Mods - [x] JTAG(And audio rewire) - [x] Meshcore/Meshtastic - [x] Vibrator active - [x] Keyboard IRQ to IO2 - [ ] QWIIC Connector - [ ] SAO Connector - [ ] I2C swap on camera - [ ] Neopixels with passthrough - [ ] Vibrator pulldown - [ ] Display pullup(**Maybe**) - [ ] Hack in Audio Codec(Also for headphone jack) - [ ] Remake M2 with perma mods(**Maybe**) - [ ] Remove Pullups for I2C2 bus(Addon bus, making it *potentially compatible with I3C*) ## Details about all the mods ### JTAG & I2S So as I had said in [this post](https://starlightwebsites.nl/Blog/WHY2025Badge/The-WHY!(badge)) I've modded the board to have JTAG and changed the audio bus pins This was needed for you know, JTAG and uart, but also so that I have access to the second USB bus. This mod **IS VERY HARD** the traces are tiny, USB is needy with proper length and for I2S the wire lengths are short. But the hookup wire needed is like 0.02 or 0.01 mm. Super thin and fragile. I had multiple times that the JTAG mod just sprung lose and resoldering that... is hell... But it works and I can debug software on the P4 ### Meshcore/Meshtastic This mod has been done to get 2 wires connected for the Lora communication protocols. I will keep it short on here since most is nicely documented by Peetz0r on his [website](https://peetz0r.nl/badge) The most important is this picture of what to do where  ### Vibrator Nothing too hard. It is a 0201 so some care is needed, but its just desoldering it and resoldering it on the pad above ### Keyboard IRQ on IO2 This is also not a hard mod. Its one of the easiest in my opinion. The only reason to do this is to get super fast IRQ's from the keyboard chip and in term quick key actions ### I2C swap on camera This mod needs to be done ### Neopixels This mod needs to be done ### Vibrator pulldown This mod needs to be done ### Display pullup This mod needs to be done ### Audio codec hack This mod needs to be done ### M2 remake This mod needs to be done ### I2C2 pullups This mod needs to be done
