Proto Module could be more useful
The PROTO module is kind of an poor design. It is just a perf board. It would have been more useful to at bring out the header pins to solder points on the PCB. The way it is now you have to solder wire to the SMT pad under the header. Makes no sense. Also, bring out the 3.3, 5V, and GND to busses so they can be used. I am just going to make my own proto module. I finally managed to locate the Samtec header part number but they take a few weeks to get.
Could you share the Samtec header part number and the seller's link ?
