Unlike the original Zero, it does not include an embedded debugger/programmer. Instead, the [UF2 Bootloader](https://github.com/microsoft/uf2-samdx1) is used to program this board. The SAMD21 is a ARM Cortex-M0+ micro-controller. It has 256KiB of flash memory and 32KiB of RAM. -Note: The official Arduino Zero using the native USB port and the Adafruit -Metro M0 Express should also work with board definition. +@note The official Arduino Zero using the native USB port and the Adafruit + Metro M0 Express should also work with this board definition. ## Hardware
