Pinout

Hover the mouse over a pin function for more information. Clicking in a function will tell you how to use it in Espruino.

  • Purple boxes show pins that are used for other functionality on the board. You should avoid using these unless you know that the marked device is not used.
  • ! boxes contain extra information about the pin. Hover your mouse over them to see it.
  • 3.3v boxes mark pins that are not 5v tolerant (they only take inputs from 0 - 3.3v, not 0 - 5v).
  • GND is ground (0v).
  • VBAT is the battery voltage output (see the Espruino Board Reference).
  • ADC is an Analog to Digital Converter (for reading analog voltages)
  • PWM is for Pulse Width Modulation. This creates analog voltages from a digital output by sending a series of pulses.
  • SPI is the 3 wire Serial Peripheral Interface.
  • USART is a 2 wire peripheral for Serial Data.
  • I2C is the 2 wire Inter-Integrated Circuit bus.
