Before proceeding, make sure that the main switch on Yozh robot is in OFF position.
- Install CircuitPython 7 on your Itsy Bitsy RP2040 microcontroller as described in Adafruit Learn Guide.
- Solder two 14-pin male headers to the Itsy Bitsy board. If you need help with that, check this guide - it is about a different board, but the process is the same, except that Itsy Bitsy uses two 14-pin headers. Do not solder headers to the short edge!
- Insert the Itsy Bitsy board into the female headers on the main Yozh board, with the USB connector facing out. Double-check that it is plugged correctly - it is easy to make a mistake, shifting the board by one position.
- Insert the two 4-pin 15mm male headers into the 2*4 female header on the main Yozh board.
- Take the top plate board, with the OLED display, and place it on top of the robot so that the male headers from the previous step are plugged into the 2*4 female header on the bottom of the top plate. Double-check that it is plugged correctly by looking from the sides. Now double-check again.
- Use the M2.5 screws to attach the top plate to the standoffs on the Yozh robot.
- Plug the front distance sensor board into male headers at the front of the robot, with the sensors facing out.
- (optional) Attach googly eyes!
