There was a lot of interest last year in doing a surface mount soldering workshop (@kaspar @gbathree @biomurph @kina.smith @dusjagr). Anyone else interested in helping to organize something like this and/or have any good ideas for a simple/cheap board to make (e.g., GOSH2018 badge?).
The Adafruit ItsyBitsy M4 is a pretty cool little SAMD51 dev board (the SAMD51 is the successor to the popular SAMD21) that can be made for ~$5. It’s plenty fast and has lots of flash/ram for running CircuitPython, which could facilitate a nice follow-on activity/workshop.
