Base for ESP32 30-pin expansion module
thingiverse
A base for the expansion board for the ESP-32 30-pin development module. The board provides additional inputs and outputs for power, and headers with power and ground for each GPIO. It is used with the 30-pin development modules with 25mm pin spacing. The base serves to keep the board clear of the workbench and any small metallic pieces or tools that could cause shorts. It could also be used as a base for a matching cover.The board appears to be built using the UNO template so that UNO cases and bases could be used, but the size is different. It seems like the manufacturer just misread the UNO board specifications, and UNO bases will not fit.Two versions are provided. The basic version includes mounting holes with a diameter of 4.3mm to accept threaded inserts for M3 screws. The A version includes mounting holes to accept self-threading M3 screws.The FreeCad files are included so any required modification can be made.
