Solder it once: a panel-mount OLED module you can move between every project

Galopago's two-board KiCad stack (published June 16, 2026, covered by Hackaday June 18) fixes the chronic bare-OLED-enclosure problem. A display board packages an SSD1306-compatible OLED with a 3.3 V LDO, auto-reset, and six indicator LEDs; a connector board routes everything to a screw terminal block. The whole assembly fits inside a stripped $2–5 AliExpress panel meter. BOM totals $15–50; JLCPCB PCBs run $5–10 per set of five. Beginner-to-Intermediate difficulty — routine 0805 SMD work, plus one tricky step: a 30-pin, 0.7 mm pitch OLED flex cable.
