Supported boards
polyfence runs on any board that can post coordinates to /api/v1/evaluate. The boards below have firmware ports we maintain — the wizard at /devices/new flashes them in a few minutes. Other Espressif and nRF52 boards mostly work too; tell us what you’re using and we’ll add it.

Plug in, walk through the wizard, watch it report. End-to-end working today.
Supported
Seeed Wio Tracker L1 Pro
Seeed Studio · nrf52840
Field-grade tracker with LoRa SX1262, GPS, OLED, and a battery. Today the device reaches polyfence through the wizard's browser tab; LoRaWAN backhaul on the roadmap.

Heltec Wireless Tracker Rev 2.0
Heltec Automation · esp32s3
ESP32-S3 with native WiFi, LoRa SX1262, GPS, and OLED. Firmware port in development — first board with native WiFi + LoRa + GPS will support untethered fielding without the browser bridge.

LilyGo T-Echo Lite
LilyGo · nrf52840
Solar-powered nRF52840 with LoRa SX1262 and GPS. Same chip family as the Wio Tracker — port in development. Pairs naturally with a LoRaWAN gateway when that integration ships.

The polyfence-embedded C library runs on any MCU with libc and libm — Linux, macOS, ARM Cortex-M4+, bare metal with newlib. If your board has WiFi, cellular, or LoRa, you can post coordinates to the evaluate API directly from your firmware. Reach out if you’d like us to prioritise a specific board.
