Espruino Pico JavaScript Microcontroller Board

The Espruino Pico is a small microcontroller board running JavaScript to make controlling electronics easier than ever. It is programmed using directly in JavaScript as the microcontroller has an interpreter built-in. There is a Chrome App called Espruino Web IDE. The App provides a simple and easy to use user interface to programme the board and plenty of code examples to help you get started.

It can be used from virtually any device with a USB port so you can get started in seconds. Rather than just writing code, deploying it to a board and hoping it works, you can now interact with the hardware directly. You can send any JavaScript command to Espruino Pico and it executes straight away and makes it a great way to control electronics from your computer. The fast response time allows for quick and easy debugging and is a great way to test your project.

The Espruino firmware is so compact that it fits inside a single chip - reducing power consumption, cost, and size. Potentially, an Espruino Pico can run for over 10 years on a single AA-sized 3 V lithium cell.


22 GPIO pins: 9 analogue inputs, 21 PWM, 2 serial, 3 SPI, 3 I2C
All GPIO is 3.3 V but 5 V tolerant
2 rows of 9 0.1" pins, with a third 0.05" row of 8-pins on the end
On-board USB "PCB Type" connector - plugs directly into a USB port
Two on-board LEDs and one button
STM32F401CDU6 CPU - ARM Cortex
On-board 3.3 V 250 mA voltage regulator, accepts voltages from 3.5 V to 16 V
Current draw in sleep: 0.05 mA = over 2.5 years on a 2500 mAh battery
On-board FET can be used to drive high-current outputs
While the main advantage of the Espruino is its instant execution, it can also be used as a traditional
15 x 33 x 3 mm / 0.6" x 1.3" x 0.12"
