The new Espruino Pico board, now crowdfunding on Kickstarter
Talking to Gordon WIlliams about the Espruino Pico
The Espruino Pico board looks something like the DigiSpark. However, unlike the DigiSpark which has an ATTiny85—which smaller, and a less powerful than your standard Arduino—the Espruino Pico has a STM32F401 ARM Cortex M4. So this tiny board is just as powerful than its larger sibling which uses a STM32F103.
The specifications of the new board are:
- 1.26 x 0.6 inch (32mm x 15mm)
- 22 GPIO pins : 9 Analogs inputs, 21 PWM, 2 Serial, 3 SPI, 3 I2C
- All GPIO is 5 volt tolerant
- 2 rows of 8 pins, with 12 pins on double-sided end connector
- On-board USB Type A connector
- STM32F401 CPU – ARM Cortex M4, 384kb flash, 96kb RAM
- On-board 3.3v 150mA voltage regulator, accepts voltages from 3.5v to 20v
- 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
The Kickstarter campaign for the Espruino Pico is already funded, and still has just over a week to go if you’re interested in picking up one of these boards.
