  • microSD™ card connector
  • STMod+ and PMOD connectors
  • 8 Mbit-PSRAM
  • 64 Mbit-Quad-SPI Flash
  • 8 LEDs
  • Reset push button
  • 4 direction-joystick with selection
  • USB OTG FS with Micro-AB connector
  • Compatible Arduino™ Uno V3 connectors
  • On-board ST-LINK/V2-1 debugger

Buying

This board can be purchsed direct from ST or from distributors.

Getting Started

And you're ready to go! Follow the Getting Started Guide for details on getting the IDE connected via USB. You can communicate with the board via the USB STLINK USB connector or the OTG FS USB connector (OTG FS takes priority if connected).

Information

Pinout

Note: All pins on Arduino headers are available via the Nucleo object, eg. Nucleo.A1.

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).
  • 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.
