Schematics

These schematics only show the components and the pin number to connect with.

For Cubetto I’m using the following parts:

• 1x Shrimp
• 1x XRF module + Active (!) XBBO
• 1x L293
• 2x GM3
• 2x Wheels
• 2x CNY70
• 1x Voltage regulator kit (not shown in schematics)

(Click on the part for the link to my supplier.)
(Not listing small parts like resistors, LED’s, etc.)

For the Interface Board I’m using the following parts

• 2x Shrimp (connected with I2C, just connect A4 with A4 and A5 with A5)
• 2x CD4052
• 1x button (fits perfectly in the hole of the interface board)
• 1x XRF module + Active (!) XBBO
  (connected to Shrimp 1)
• 1x Voltage regulator kit (not shown in schematics)

(Click on the part for the link to my supplier.)
(Not listing small parts like resistors, LED’s, etc.; they’re from Tayda Electronics.)

There’s a small “repair code” in the interface_board_2 sketch; I accidentally wired my LEDs wrong and fixed it in the code.
Remove/comment the part between “START correction for wrong wiring” and “END correction for wrong wiring” if you wired everything right .
