Why buy instead of DIY?
Real storage
The built-in SD slot skips the 3MB SPIFFS ceiling you’d hit flashing a raw board.
No soldering
Pre-flashed and wired up. Plug in power and it’s already running.
Built to last
A proper enclosure and connectors, not a bare dev board on a desk.
Keeps the project going
Every one sold funds the free firmware — updates, new examples, and support keep coming.
Still wanna build your own?
It's free — the firmware flashes onto any ESP8266 or ESP32-S3 board you already have.
