The SAM 15x15 is an Arduino development board of just 15 x 15mm, with the same powerful controller as the Arduino Zero: the SAMD21G18. Despite the small size, it has more I/O pins than the Arduino Zero: 34 instead of 20. Due to the very small dimensions it will fit easily into all embedded electronic projects.

SAM 15x15 features
  • Controller: Atmel ATSAMD21G18, 32-bit, 48MHz, ARM Cortex-M0+
  • Digital I/O pins: 34
  • PWM outputs: 24 (PWM DAC)
  • Analog inputs (ADC): 14
  • ADC resolution: 12-bit
  • One 10-bit DAC
  • Flash memory: 256 kbyte
  • SRAM: 32 kbyte
  • EEPROM: 32 kbyte (emulated in Flash)
  • Preprogrammed customized bootloader
  • Programming and debugging through the integrated USB port

The SAM 15x15 board contains also:
  • One free LED
  • Combined RX/TX LED
  • Voltage regulator 3.3V for the USB powering
  • Power supply reverse polarity protection
  • High voltage protection for the USB

SAMD21G18 with pins
For hobbyists, the drawback of the SAMD21 is that it is only available in SMD. When blown up, it is pretty tough to replace it because no IC socket can be used. This can be solved with the SAM 15x15 board, which transforms the SAMD21G into a pin version
