TinyPICO Dev Board (Mini ESP32)

What is TinyPICO Dev Board ?

TinyPICO dev board is the world’s smallest, fully-featured ESP32 development board, designed to give you access to the power of the ESP32’s dual core 240 MHz processor and internet connectivity, all in a package smaller than your thumb!

TinyPICO ships with mainline MicroPython pre-installed and supports Arduino IDE and Espressif IDF, so you have the flexibility to code the way you want. For basic coding examples on our TinyPICO website and all libraries are being added to the TinyPICO GitHub repository.

TinyPICO has been designed with two isolated power paths: a 5 V path and a 3.3 V path. Any components that are not needed for operation via battery or via the 3.3 V power pin are isolated within the 5 V power path, and are totally shut down when no USB cable is plugged in. Deep sleep has been optimised for all development platforms, and though we have seen it go as low as 10 uA, our official current rating in deep sleep is 18 uA.

TinyPICO is fully open source. All hardware is released under the CERN open hardware license, so please make yourself familiar with it before you decide to fork or use the files. All software is released under the MIT open software license, so again, please make yourself familiar with it before you decide to fork or use the files. All of the design files for the TinyPICO and all of the shields shown here are available from the TinyPICO GitHub repository

TinyPICO is currently in the “coming soon” section of Crowd Supply, which means that they’re gauging interest for a crowdfunding campaign launch.

Update: TinyPICO has now launched on Crowd Supply.

Unexpected Maker

I’ve spent my life sitting in front of a computer screen for work and for play and recently I decided I wanted to do more things with my hands… electronics, woodworking or 3D printing… I don’t mind what it is, so long as I am not staring at a computer screen. Please join me on my journey as I make and break projects, discover new things, and hopefully inspire you to go out and make something too!
