They were intended for use on a breadboard. Your socket is an Augat one, with high quality machined sockets for maximum 0.43mm circular pins. The ones in CMOD A7 are most likely cheap square 0.64x0.64mm pins. I think two 24 positions headers will be better for a custom made PCB. Digikey part: S7022-ND

OMG, what the heck were you doing with that board?
Tried to save the board, secured with a lot of epoxy, better an ugly working board than a pretty broken one. I had to connect two USBs(program+comm) and power barrel connector before.

My Arty had a similar fate. From the image above one can see it is quite hopeless, unless you can solder small wires directly on FTDI chip pads.
It looks bad, but it's back to life, again. I lost all pins, Ground is easy, positive, from the 5V rail.

It worked, thank you so much!

Well, I am not at that level, I use this board for small projects, like an Arduino. I am learning, so I would abuse this board. Epoxy is to secure the wires, they are 5mils in diameter. This board is very well designed. Since the FTDI schematic is not public, I assumed the big capacitor near the USB is 5V, but it is 3.3V. The board took it gracefully, until I noticed the power supply part is hot. It works well, now.
