Once you’ve uploaded code, you can inspect and change variables (including functions!) while your program is running. There’s loads of documentation, tutorials and support for a huge range of different hardware too. See how to get started here, or if you have any questions ask away on the Espruino forums!
- 30mm x 23mm (1.2 x 0.9 inch)
- On-board Micro USB connector
- 2 rows of 11 0.1” pins, with 2 extra 0.1” holes
- 21 GPIO pins : 8 Analog inputs, 20 PWM, 1 Serial, 3 SPI, 3 I2C
- Three on-board LEDs (2x user programmable, 1x WiFi activity) and one button.
- STM32F411CEU6 32-bit 100MHz ARM Cortex M4 CPU, 512kb flash, 128kb RAM
- ESP8266 WiFi (802.11 b/g/n)
- All GPIO is 5 volt tolerant (Arduino compatible)
- RTC with external oscillator
- On-board 3.3v 250mA voltage regulator, accepts voltages from 3.5v to 5v
- Current draw in sleep: < 0.05mA - over 2.5 years on a 2500mAh battery
- 500mA polyfuse on board
The Espruino’s fast response time has a lot of advantages. It allows for quick and easy debugging and is a great way to test your project before your big reveal. In addition, you can control the Espruino from almost anything - Windows, Mac OS, Linux, RasPi, Android, anything that can talk to a USB Serial port.
While the main advantage of the Espruino is its instant execution, it can also be used as a traditional board through a Web-based IDE hosted on your computer. The microcontroller also uses less power than Linux Boards (although its of course a lot less powerful as well) so will run longer on battery power, it has loads of IO pins, and it can be used as an IO board for PCs, Macs, or Rasp Pis without having to program it first. Simply take the Espruino out of its packaging and get started!
NOTE: The Wifi of this board is based on ESP8266 and might not work with CircuitPython. CircuitPython typically use Airlift that rely on ESP32 with better support for TLS such as this breakout board.

This is the latest unstable release of CircuitPython that will work with the Espruino WiFi.
Unstable builds have the latest features but are more likely to have critical bugs.

Every time we commit new code to CircuitPython we automatically build binaries for each board and language. The binaries are stored on Amazon S3, organized by board, and then by language. Try them if you want the absolute latest and are feeling daring or want to see if a problem has been fixed.
All previous releases are listed on GitHub, with release notes, and are available for download from Amazon S3. They are handy for testing, but otherwise we recommend using the latest stable release. Some older GitHub release pages include the same binaries for downloading. But we have discontinued including binaries as assets on newer release pages because of the large number of files for each release.
