This compact development board utilises an ESP32 processor for a very low-power project foundation including WiFi, Bluetooth, MicroSD storage, an onboard microphone and the option of a 2MP camera (select version above before adding to cart)!

With the added flexibility of direct LiPo powering and charging thanks to the dedicated JST (PH2.0) connector, this mini dev board is great for remote, low-power monitor projects where size and power consumption are key.

Whilst this won't run a full operating system like the Raspberry Pi, the ESP One is compatible with Arduino libraries and can be programmed using popular options such as Microsoft Visual Studio Code. You can even use most of your existing Raspberry Pi HATs and pHATs with this board thanks to the standardised 40-pin connector format.

Other great features include the colour-coded header, onboard reset button, IPEX antenna connector, LED indicators and more!
