Many [re]purposes and debug efforts could aided by a comprehensive description of the various low level protocols available on the XO motherboard. There are a variety of headless and headed connectors visible on the XO. The following is an attempt to identify them completely.

The XO motherboard also features several standard high and low level protocols.

  • I2C
    • Theoretically used for the DCON - A datasheet should be obtained for the Himax HX8837 chip and the I2C pins/traces should be identified.
  • 3.3v TTL Serial
