What is typically used to adapt 1mm diameter pins so they'll fit into the smaller through-hole protoboard sections like on the MKR Proto Shield? I'm sure this is slightly larger than normal, but it's coming off of a 5V/3A output switching regulator that I'd like to solder onto the MKR, so that may explain their size. Likewise, a 10x8 matrix would be ideal (MKR Relay Shield section). I don't really need something this large for nominal use, but I remember my old uBlox GSM modem requiring up to ~2500mA during carrier registration, so it's really just for this brief period (or, to the contrary, indefinitely if there are issues finding service.)
Thanks
