Nerdonic Atom X1 is the World’s Smallest 32-bit Arduino Compatible Board

Tiny 32-bit Dev Board. 14.9mm², Breadboard, 0.95g, 3-20V input, I²C, 8 PWM, Serial, 6 ADC, Prog LED.

There is a new board in the ecosystem which claims to be the world’s smallest 32-bit Arduino board. The name of it Atom X1 and measures 14.9×14.9 mm.

Atom X1 specifications:

  • MCU – Microchip Atmel  SAMD21 Cortex M0+ MCU @ 48 MHz with 256KB flash, 32KB SRAM
  • I/Os via 2x 5-pin 2.54mm pitch headers
    • Up to 8x digital I/O
    • Up to 8x PWM
    • Up to 6x analog (ADC)
    • 1x UART
    • 1x I2C
    • 1x reset
    • Limits – 3.7V, 7mA
  • USB – 1x micro USB port
  • Programming – via micro USB port or SWD header
  • Misc – Power LED, user LED, button
  • Power Supply
    • 3.3-20V (regulated to 3.3v) via power Pin 1
    • 3.3V via power pin 2
    • 5V (regulated to 3.3v) via Micro USB port
    • Current Draw Atom X1 = ~10mA
  • Dimensions – 14.9 x 14.9 x 4.4mm
  • Weight – 0.95 grams

The board is breadboard compatible, pre-flashed with Arduino Zero bootloader, and can be programmed in the Arduino IDE just like the original board.

The project has been launched on Indiegogo. Early bird rewards start at 10 GBP (~$13.2 US) for the board with shipping adding 2 GBP to the UK, and 7 GBP to the rest of the world. Delivery is scheduled for December 2017.
