ESP32-C3 SuperMini
Espressif (generic / various) · esp32c3
Compact WiFi-capable ESP32 dev board with native USB. Cheapest path to a Polyfence node — pair it with an external GPS module if your use case needs location.

Reference boards
These are the boards we build and maintain firmware for — flash one with the setup wizard and it’s reporting zones in minutes. Polyfence is the geofence layer at heart — a portable C library (polyfence-embedded), so if you’ve got your own hardware you can run the same zones there instead. Most 32-bit MCUs and Linux are fair game: nRF52, ESP32, STM32, RP2040.
Ready to onboard (4)
Plug in, walk through the wizard, watch it report. End-to-end working today.
