microgrid48v.kicadsch is the first capture of the complete validated connectivity table. It embeds project-specific rectangular symbols so every named functional pin remains visible without relying on a workstation library. The current capture contains 156 symbols and 502 pins across 132 logical nets: 127 connected global-label nets and five intentional no-connect pins. It includes the complete TMCS1123 and AMC3330 support networks, ADC filters, analog reference buffers, and isolated RS-485 supply connection.
