“This is the first time you’ve been able to get a scripting language in such a small package, and it opens a whole world of possibilities. Rather than just writing code, deploying it to a board and hoping it works, you can now interact with the hardware directly – querying and changing voltage levels and interacting with external components until you get everything just as you want it.
This is all made possible by the Espruino firmware, which is so compact that it can fit inside a single chip – reducing power consumption, cost, and size.”
Features include :
– 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 8 pins, with 12 pins on double-sided end connector
– On-board USB Type A connector
– STM32F401 CPU – ARM Cortex M4, 256kb flash, 64kb RAM
– On-board 3.3v 150mA voltage regulator, accepts voltages from 3.5v to 20v
– Current draw in sleep: <0.1mA – over 2.5 years on a 2500mAh battery
