Description
Case for headless mod of Gaggiuino which uses the 'hacked' FW from https://github.com/a4vgx7b2M/gaggiuino-esp32-loader.
Will hold the ESP32-S3 devkit (e.g here), JST XH 4pin male header (here), and SD car reader without voltage regulator (here).
Reason I opted to use JST XH over JST PH that the official headless board uses, is so that the original cabling I had used on my Gaggiuino Gen2 with Nextion Screen could be reused straight away.
For optimal results print with layer height of 0.15mm or less. I printed in PLA, though other materials might work as well.
Original onshape project here, in case you need to adjust board height or dimensions slightly for your use.

Soldering note: The picture shows wires soldered from the top, however, the latest version of the model requires you to solder wires from the bottom of the board.
