Description。Cherry MX Keyswitches are top-of-the-line mechanical keyboard switches. They're satisfyingly "clicky"， reliable up to tens-of-millions of key presses， and a standard in gaming and programming keyboards across the globe. With the SparkFun Cherry MX Switch Breakout we have made the switches more easily adaptable to breadboard or perfboard-based projects. The Cherry MX Switch Breakout is a perfect prototyping tool for projects ranging from a single-key user-input to fully-custom 101-key keyboards.。In addition to breaking out the switch contacts to breadboard-compatible headers， the Cherry MX Switch Breakout also provides access to an optional switch-mounted LED. Plus， the pin break-outs are designed with keyboard matrix-ing in mind， so you can interconnect as many boards as you'd like into a row-column configuration， keeping the I/O-pin requirements as low as possible.。Note：If you are looking for a Cherry MX Switch to use with this breakout， we've got you covered!

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!。Get Started with the MicroMod RP2040 Processor Guide。Features。RP2040 General Features。Dual Cortex M0+ processors， up to 133 MHz。264 kB of embedded SRAM in 6 banks。6 dedicated IO for QSPI flash， supporting execute in place(XIP)。30 programmable IO for extended peripheral support。SWD interface。Timer with 4 alarms。Real time counter(RTC)。USB 1.1 Host/Device functionality。Supported programming languages。MicroPython。C/C++。Specific Peripherals made available on MicroMod RP2040。1x USB dedicated for programming and debug(Host capable)。2x UARTs。2x I2C。2x SPI。29x GPIO。2x Digital Pins。3x Analog Pins。16x PWM。128Mbit/16MB(external)flash memory。Status LED。VIN Level ADC
