Hi, Good! I'll try to get you a board shortly. I'm moving atm and everything is a bit messy, so I can't have a look myself at the connectors' position and the board before Tuesday.
One thing we should be careful about is that the board will eventually be cased, and the JTAG mini-board should fit without removing the case. I would replace the big USB connector with a mini-USB one. The connector at both the cable and board side are smaller, which would be probably easier to fit in the case. I prefer to avoid plastic screws as they add complexity to the M1 design. In my opinion, the best solution is no stabilization at all which is simpler and cheaper (ie the board holds by itself from the JTAG and UART connectors). For this purpose, I suggest a combination of these techniques (to your choosing): * move the USB connector closer to the UART and JTAG connectors to minimize the lever effect through the JTAG board. * the mini USB connector probably helps as well. * make a smaller board (also helps fitting in the case) by ** using the QFN version of the FT2232H. ** using smaller SMD passive components (like 0402 instead of 0603). The M1 already uses 0402 components, so we can also share the same inventory this way. ** putting components on both sides of the board.
