Otsi - PCBs rev2

  • February 11, 2025

Info

The second PCB hasn’t been fully made so this project log isn’t fully completed at this point

Overall idea

This time the idea has changed drastically. First of all, now Otsi is composed of two PCBs.

  • The first one being It’s main PCB where battery is placed as well as Pico and all different ICs
  • The second one being a UI PCB. That means that there are gonna be placed all the buttons, 0.96inch display and a RGB LED Another change is that right now Otsi is no longer gonna be a handheld but rather a micro laptop of some sort with a lid-mounted main display. Other changes are:
  • Different extension ports. This time there are 3x 4pin 3.5mm Audio Jacks that are gonna be connectors for I2C extensions
  • Improved ergonomics
  • different User Input. From now on Otsi is going to be based around a 5 position button with 3 additional ones.

And here is our early idea of a second design
