SparkFun MicroMod RP2040 Processor／DEV-17720
【影片】：https://youtu.be/N15CiFd2y_w
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.
Note: While the MicroMod RP2040 Processor Board is designed to mate with M.2 Connectors that are populated on Carrier Boards, the RP2040 is not compatible specifically with the Machine Learning Carrier Board.／雖然 MicroMod RP2040 處理器板設計用於與裝在載板上的 M.2 連接器配合，但 RP2040 並不特別兼容機器學習載板。
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!
