Click for larger image
Sensor mezzanine board. Mount directly on top of the Mark III Controller Board to gain additional functions. Can be be used with either the OOPic or Standard version of the Mark III. Comes with the minimum number of parts needed to make the Sensor Board functional:
  • 1 bare PCB
  • 1 6-pin stacking header
  • 1 40-pin stacking header
  • 2 3-pin servo headers
  • 1 PCF8574 I²C Expander
  • 1 5-pin I²C connector
  • 1 6-position DIP switch
  • 1 Piezo Buzzer
  • 1 Handyboard-compatible 8-bit digital I/O port consisting of:
    • 1 22KOhm resistor network
    • 1 47KOhm resistor network
    • 1 8-pin female header
    • 1 dual-row 8-pin female header
Assembly required.

Printed Circuit Board has locations for:

None of these are included, and must be purchased as separate kits.

Picture shows a fully-stuffed prototype of the Sensor board. Actual Sensor board will have several minor differences. A new picture will be posted when available.
