Xinabox Cs11 - Core With Sd Card Interface (Atsamd21G18)

Part number: CS11
Description
Based on the ATSAMD21G18, this xChip is a core CPU module that performs as a low-power microcontroller. It features a 32-bit ARM Cortex-M0+ processor supporting 256 KB of flash (8x more than the ATmega328P), 32 KB of SRAM (16x more than the ATmega328P) and runs to a 48 MHz maximum frequency.
Thanks to shared architecture with the Arduino M0, it works seamlessly with the Arduino platform and comes with an SD card interface so you can add functionality.
