Arduino ABX00012 SBC, Arduino MKR Zero, SAMD21, ARM Cortex-M0+, 32bit, 32KB RAM, 256KB Flash, 8 I/O pins

The Arduino MKR Zero brings you the power of the Arduino Zero in the smaller MKR form factor. It acts as an educational tool for learning about 32-bit application development. It has an onboard SD connector with dedicated SPI interfaces that allows you to play with files without the need for extra hardware.
