A project log for TARS SAO

A simple add-on inspired by Interstellars robots with 6 touch buttons, a speaker and a 160x80 pixel display, controlled by an RP2040 board

As you can see in the videos, I'm using a WaveShare RP2040-Tiny module, that comes with a "programming dongle", meaning you can program it via usb-c and use the boot doot and reset buttons to your liking. If you're done, you're left with a small PCB that's also SMD mountable - nice!

The ST7735S display that I'm using, can be soldered either through a slot on the back of the board, or just under the display. So I created a footprint that mounts on the front, so I will have more room on the back for the RP2040 module and some light panels for highlighting the "TARS" and "TARS" in braille font. I can probably use the onboard neopixel and safe 10ct - bargain! 

The display footprint is created, next up is going to be the RP2040-tiny module. In parallel I will test some touch button code with rudamentary hardware.
