Case study
MapMe (DEVSAN-NAV)
XIAO ESP32-C6 + OLED ambient display that mirrors phone navigation and notifications.
Summary
A pocket-sized glance display that pairs over BLE with the phone via ChronosESP32 and surfaces next-turn cues and notifications on a tiny OLED. Built so the phone can stay in the pocket and the eyes can stay on the road.
Problem
Checking a phone screen for the next turn while driving is exactly as bad as it sounds. I wanted a small glanceable display that mirrors only the cues that matter — next turn, distance, direction — so the phone could stay in a pocket and the eyes could stay on the road.
Architecture
Result
MapMe pairs with a phone running Google Maps and shows next-turn cues on an OLED via BLE. Glanceable cues over full map redraws; hands stay on the wheel. Built, working, and shared as a real IoT artifact.
Highlights
- Mirrors phone notifications and Google Maps cues over BLE
- Tiny footprint — XIAO C6 + SSD1306 OLED
- Glanceable design — no map redraws, just what matters next
