README

OLED hairpin A1

This is the larger-screen, replaceable-CR2032 prototype revision. Open oled-hairpin-A1.kicad_pro in KiCad 10. The board is 78 × 25.5 × 0.8 mm; the OLED and USB-C connector are on the front, while the CR2032 retainer, MCU, and support parts are on the back. USB-C is for programming and external power; it does not charge the cell.

This is an electrically routed prototype draft, not a fabrication release. The OLED flex fit, CR2032 runtime, battery cover, and clip attachment require prototype measurements. No firmware is included. Read design-record.md before ordering.
