Universal Board v1.1.1-beta

EEPROM 3.3V fix, SATA replaced with XH connectors, fuse added, I2C4 EEPROM pins added.
By Clemens Elflein |

v1.1.1-beta is a hardware revision fixing a critical EEPROM power issue and switching the inter-module connectors.

Changes

EEPROM 3.3V fix — The 3.3V supply for the EEPROM was not connected in the previous revision. This is now routed correctly, fixing #6. Without this fix the core board cannot read the carrier board’s EEPROM and therefore cannot auto-detect the attached mower model.

XH connectors replace SATA — The inter-module data connectors have been switched from SATA to XH connectors. SATA was a pragmatic choice in early revisions; XH connectors are more appropriate for this use case and easier to source.

Fuse added — A fuse has been added to the power path for protection.

I2C4 EEPROM pins — Pins for the I2C4 EEPROM interface have been added to the board.

BOM fix — Corrections to the bill of materials.
