Four-layer 32 x 30 mm KiCad board with single-sided assembly, a 3D-printed 35.7 x 33.9 x 9.95 mm case and a magnetic pogo-pin dock.

AM/FM Receiver Molecule

amfm-receiver-molecule·Adom·PCBA 102.5 x 102.5 mm, 96 x 96 mm large-pin grid, 4-layer

USB-powered AM/FM receiver on an Adom Molecule: discrete BJT and op-amp superhet (10.7 MHz and 455 kHz IFs), STM32G0B1 tuning, self-calibration and USB audio over one USB-C cable. 96 x 96 mm pin grid, 4 layers, KiCad 10.

Solar MPPT Power System

A 30 W solar battery charger with regulated 5 V and 3.3 V rails: an STM32G031 running perturb & observe MPPT and a CC/CV charge state machine, steering a TI LM5175 4-switch buck-boost through a single analog control input. Four-layer KiCad board, schematic and PCB generated from Python, with an electrothermal simulation run against the published board file.

Nametag Blank Large LED
