Swagbadge 101: Hardware and SAOs
summary
Conference badge is a tiny MicroPython-capable dev board built around an ESP32 Lolin32 at $3 with only five main components: two 0.96" I2C OLEDs, two buttons, touch sliders and USB battery charging. About ~294 badges produced after a row of bad PCBs and an OLED variant wired backwards; hundreds of pin cuts and solder bridges were needed. Four 6‑pin SAO headers expose power, I2C and two GPIOs—included protoboards, a Tux touch SAO, a solder‑rocket and a planned LED VU add‑on all work with the badge over USB/Wi‑Fi.
