48 Channel Logic Analyzer – Case & Front Panel

This repository provides a 3D-printed enclosure and a matching front panel for the 24-channel open source logic analyzer boards by gusmanb. The project combines two logic analyzer boards into one compact 48 channel device, featuring an integrated USB hub and a fully labeled PCB front panel.

Additional Tweaks

I use flexible silicon wires to connect the target. The wires are labeled with printable heat shrink tube (Printed on a Brother P-touch label printer).

Wires for the channels are bundled on a 2x16 connector:

Notes

PCB Front Panel

• The case is designed for the (default) PCB thickness 1.6mm

• Some PCB manufacturers add by default a mark on the silkscreen. That is not wat you want on a front panel. I ordered my PCBs at JLCPCB and selected "Remove Mark" for High-Spec option "Mark on PCB".
