eye2see Probe Hardware

The first dedicated eye2see Probe hardware is shown below. 

This uses a simple 2 layer PCB (fabricated here by OSHPark, I also use PCBWay and both give excellent service and quality). The PCB forms the bottom of the enclosure.  The Seeed Xiao RP2040 is soldered to the PCB, along with the FPC connector for the 132x32 LCD, Qwiic/StemmaQT connector and 3pin 0.1" male header (both connectors carry ground, SDA and SCL for attaching to the target). Captive nuts fit in 4 holes in the corners of the PCB.

The enclosure "chassis"  was designed using OpenSCAD and is FDM 3D printed in PLA (on my Monoprice MiniDelta II), holds the LCD securely, and provides clearance for the FPC cable, connectors and components on the PCB.

Finally, the enclosure top is laser cut from 1mm black acrylic, and bolts through the chassis to the captive nuts in the PCB.

This stack makes a rugged, compact and inexpensive enclosure.
