## Description

The Espruino WiFi is a tiny WiFi-enabled development board that runs JavaScript directly — no computer connection required after programming. Built around the STM32F411 (Arm Cortex-M4 at 100 MHz) with an ESP8266 WiFi module, it lets you write, upload, and debug JavaScript code using the Espruino Web IDE in Chrome. Your source code is stored on the board itself, so you can revisit and modify projects at any time. The IDE features a syntax-highlighted editor, graphical programming language, and live variable inspection while your program runs. Key Features JavaScript Runtime – Write and run JavaScript directly on the microcontroller WiFi Built-In – ESP8266 (802.11 b/g/n) for wireless connectivity STM32F411 MCU – Arm Cortex-M4 at 100 MHz, 512 KB flash, 128 KB RAM Live Debugging – Inspect and change variables while code is running Source Code On Board – Your code is stored on the device for future access 5V Tolerant GPIO – All 21 GPIO pins are Arduino-compatible Ultra-Low Sleep Current – <0.05 mA in sleep mode (~2.5 years on a 2500 mAh battery) Specifications MCU – STM32F411CEU6 (Arm Cortex-M4, 100 MHz) Memory – 512 KB flash, 128 KB RAM WiFi – ESP8266 (802.11 b/g/n) GPIO – 21 pins (8 analog inputs, 20 PWM, 1 serial, 3 SPI, 3 I2C) USB – Micro-USB connector Voltage Regulator – 3.3V, 250 mA (accepts 3.5–5V input) Sleep Current – <0.05 mA Protection – 500 mA polyfuse RTC – With external oscillator LEDs – 3 (2× user programmable, 1× WiFi activity) Button – 1× onboard Dimensions – 30 × 23 mm Pin Layout – 2 rows of 11 × 0.1″ pins + 2 extra holes Ideal For JavaScript-based IoT projects Rapid prototyping with a familiar language WiFi-connected sensors and actuators Battery-powered wireless devices Package Contents 1× Espruino WiFi Board Resources Getting Started Guide API Reference Tutorials Module Library Espruino Forum
