SparkFun MicroMod RP2040 Processor

Description
The SparkFun MicroMod Pi RP2040 Processor Board is a low-cost， high-performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. With the MicroMod M.2 connector， connecting your MicroMod Pi RP2040 Processor Board 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 RP2040 utilizes dual ARM Cortex-M0+ processors(up to 133MHz)：264kB of embedded SRAM in six banks
6 dedicated IO for SPI Flash(supporting XIP)
30 multifunction GPIO：Dedicated hardware for commonly used peripherals
Programmable IO for extended peripheral support
Four 12-bit ADC channels with internal temperature sensor(up to 0.5 MSa/s)
USB 1.1 Host/Device functionality
The RP2040 is supported with both C/C++ and MicroPython cross-platform development environments， including easy access to runtime debugging. It has UF2 boot and floating-point routines baked into the chip. The built-in USB can act as both device and host. It has two symmetric cores and high internal bandwidth， making it useful for signal processing and video. While the chip has a large amount of internal RAM， the board includes an additional external flash chip.
MicroMod is a modular interface ecosystem that connects a microcontroller "processor board" to various "carrier board" peripherals. Utilizing the M.2 standard， the MicroMod standard is designed to easily swap out processors on the fly. Pair a specialized carrier board for the project you need with your choice of compatible processor!
