Projects shown without client names or confidential details. Most of my work is under NDA.
A compact flex PCB Bluetooth Low Energy tag for wireless asset tracking, designed from the client’s requirements, with a Nordic nRF54L15, solar energy harvesting and a rechargeable battery.
A USB-C macro pad with an RP2040, 9 hot-swap mechanical keys, a rotary encoder and RGB lighting under every key, on a 2-layer board ready to manufacture and assemble.
A full review of a radar sensor board before fabrication: power and reset sequencing, communication buses and signal return paths, with every finding ordered by severity and the action to take for each one.
The client first tried to design this board with AI tools, without usable results. I reviewed the schematics, fixed the issues and completed a 4-layer layout in KiCad.
I checked the full bill of materials of an nRF52840 board against the schematic and footprints, reviewed component values and added a distributor part number for every part, ready for assembly.
After an AI-assisted attempt did not work out, the client asked me to redo this 4-layer power supply for an automotive control panel. I refined the power stage and completed the KiCad layout.
The client had a schematic for an nRF52840 board. I reviewed it for design issues before layout, then did the placement and routing for a design ready for production.
The client already had a two-board KiCad project. I added a CC1101 868 MHz radio module, and kept all the original board connections.
