spi screen and zero combo Brainstorming!!!

That's really cool. How did you manage to solder the Zero's GPIO to the PCB?

@obsidianspider well the board has square smd pads which match up with the 40 pins of the zero

first step is to tin all the smd pads with a thin layer of solder. gave it a quick coat with a cheepo flux pen from an old solar project, added a spot of kapton tape to make sure the vias dont touch the pi

then i clamped the Pi to the PiCB with some m2.5 bolts to hold it steady, pin by pin, hit it with the soldering iron, and push the solder in until the hole is filled, holding the iron on for just a few seconds to make sure the heat has gone though to the pad so everything is joined. repeat 39 more times!!!

the screen is the same. tin the pads, scrible on the solder pen, place the screen with some tape to keep it all in place, then touch each pin for a few seconds to melt the solder :)

@moosepr So how long until you make a board for a Compute Module 3? ;)

@obsidianspider hahaha in not sure on that one. They are a shade more complex! Would be nice though
