@bearer The Omega-Mini-Dock schematic is basically correct. This can be the version2 board with original Omega header pinout (U5). For Omega2(+) one should replace U5 to a correct header pinout and change RXD, TXD to RX0, TX0 respectively.
There are no TVS diodes (D12, D13, D14) on the Minidock.
Only these are the hardware differences between the Minidock versions:
R77, R83, R84 are 1 kOhm SMD resistors (marking 102) on the v1 board
R77, R83, R84 are 3 kOhm SMD resistors (marking 302) on the v2 board
To fix the problems of the Minidock version1 board is fairly simple:remove / desolder the R77, R83 and R84 resistors - IMHO this is the best solution :-) or solder a 0 Ohm (or a piece of wire) to the top of the R76, R81 and R82 resistors (ie. replace them with 0 Ohm) or change R77, R83 and R84 1 kOhm to 3 kOhm (so you'll have a genuine version2 Minidock ;-)
I hope all above info are correct but - as usual - make these modifications at your own risk.
Do you want further backround info?
