Espruino Pico is a tiny microcontroller board that runs JavaScript(it doesn't need to be plugged into a computer)、making it easier than ever to control electronics in the real world. You can program it with nothing but a serial terminal program、but there's also an IDE that runs in the Chrome Web browser. It's got a syntax highlighted editor as well as a graphical programming language.。Once you have uploaded code、you can inspect and change variables(including functions)while your program is running. If you make something with an Espruino Pico and need to change it a year later、your original code is still there waiting for you!。This is unpinned version、if you want pre-soldered pins、please visit Espruino Pico(pinned).。Features：33mm×15mm(1.3×0.6 inch)。22 GPIO pins：9 Analogs inputs、21 PWM、2 Serial、3 SPI、3 I2C。All GPIO is 5 volt tolerant(Arduino compatible)。2 rows of 9 0.1" pins、with a third 0.05" row of 8 pins on the end。On-board USB Type A connector。Two on-board LEDs and one button.。STM32F401CDU6 CPU - ARM Cortex M4、384kb flash、96kb RAM。On-board 3.3v 250mA voltage regulator、accepts voltages from 3.5v to 16v。Current draw in sleep：< 0.05mA - over 2.5 years on a 2500mAh battery。On-board FET can be used to drive high-current outputs。Part List：Espruino Pico(unpinned)x 1
