65% MX Keyboard (soldered)

Public Unreviewed

by gzc

65% ANSI keyboard PCB (68 soldered MX switches) for a gasket-mount case, rev B: STM32F072 under the spacebar running QMK, USB through a Unified Daughterboard on a Pico-EZmate cable, strict-grid copper, green with lead-free HASL, PCBWay bare board for hand assembly.

Step 14: Fields

the fields on the board: adom-fields solves the current density of every loaded net, the heat flow in each copper layer with the vias, and the temperature over the board; the AI reads the issues and walks the board in the app on camera

Adom Fields current and heat screen on the final board: VBUS and GND at 0.5 A peak 40 A/mm2, +3V3 at 0.1 A 12 A/mm2, under 1 C rise in still air. The 'no TVS' tag on J2 is expected: ESD protection is on the USB daughterboard.
