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).
[*]3.3 is a 3.3v output from the on-board Voltage regulator.
[*]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)
[*]DAC is a Digital to Analog Converter (for creating analog voltages). This is not available on all boards.
[*]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.
[*]CAN is for the Controller Area Network. It is not supported by Espruino.
