With a 32-bit ARM Cortex-M4F MCU, the SparkFun MicroMod SAMD51 Processor Board is one powerful microcontroller packaged on a small board! The board provides you with an economical and easy to use development platform if you're needing more power with minimal working space. With the M.2 MicroMod connector, connecting your SAMD51 Processor is a breeze. Simply match up the key on your processor's beveled edge connector to the key on the M.2 connector and secure it with a screw (included with all Carrier Boards). The SAMD51 is one of the most powerful and economical microcontrollers available so to be able to add it to your MicroMod Carrier Board is a huge advantage for your project! The ATSAMD51J20 utilizes a 32-bit ARM Cortex-M4 processor with Floating Point Unit (FPU), running up to 120MHz, up to 1MB of flash memory, up to 256KB of SRAM with ECC, up to 6 SERCOM interfaces, and other features. This MicroMod SAMD51 even comes flashed with the same convenient UF2 bootloader like the SAMD51 Thing Plus and the RedBoard Turbo. &feature=emb_title Features SAMD51 General Features : ATSAMD51J20 microcontroller 32-bit ARM Cortex-M4F MCU Up to 120MHz CPU speed 1MB flash memory 256KB SRAM Up to 6 SERCOM interfaces UF2 bootloader Specific Peripherals made available on MicroMod SAMD51: 1x USB dedicated for programming and debug (Host capable) 2x UARTs 2x I 2 C 1x SPI 1x CAN 11x GPIO 2x Digital Pins 2x Analog Pins 2x PWM 128mbit/16MB (external) flash memory Status LED VIN Level ADC Documents MicroMod SAMD51 Processor Documentation: Schematic Eagle Files Hookup Guide Board Dimensions Datasheet (ATSAMD51J20) Graphical Datasheet GitHub Hardware Repo MicroMod Documentation: SparkFun MicroMod Interface v1.0 - Pinout SparkFun MicroMod Interface v1.0 - Pin Descriptions Getting Started with MicroMod Designing with MicroMod MicroMod Info Page MicroMod Forums SparkFun Eagle Libraries contains example footprints for the M.2 connector and SMD standoff M.2 MicroMod Connector Datasheet MicroMod Reflowable Standoff Datasheet SAMD51 Documentation: ATSAM Product Family Page
