This page lists the know errors on the gm5x5x5 PCBs.
There are no known issues with the bulk order run (white pcbs), the following information is valid **only** for the prototype run (green pcbs).
==== Bulk Order #1 (white PCBs, rev 1.0) ====

=== #1 Silkscreen error (reported by dioioib) ===

**Problem**: The silkscreen has the EEPROM the wrong way around - Pin 1 should be facing IC5.

**Solution**: Stick the EEPROM in the other way around, with the "notch" facing IC5.

==== Prototype Run (green PCBs) ====

=== #1 MIDI IO pins  ===

**Problem**: The MIDI IO pins of the midi sockets (Pin 4 + 5) are switched. 

**Solution**: Either (1) use the pin-headers if you use sockets that are not mounted on the pcb or (2) break the traces to pins 4 + 5 of the sockets and solder wires to them or (3) solder the midi sockets on the other side of the pcb. 

=== #2 MISSING TRACK  ===

**Problem**: A track between D2 and R3 is missing.

**Solution**: Bridge the pins.
