SparkFun DEV-17745 Thing Plus Development Board

SparkFun DEV-17745 Thing Plus Development Board is a low-cost, high-performance board with flexible digital interfaces, and an RP2040 microcontroller.  The RP2040 utilizes dual Arm® Cortex-M0+ processors (up to 133MHz) and offers 264kB of embedded SRAM in 6 banks and 6 dedicated IO for SPI flash. This board supports both C/C++ and MicroPython cross-platform development environments that include easy access to runtime debugging. The DEV-17745 board features a UF2 boot and floating-point routines baked into the chip. The board also features an SD card slot, 16MB memory, JST single-cell battery connector, addressable WS2812 RGB LED, JTAG PTH pins, four mounting-holes, and a qwicc connector. This board comes with a dimension of 2.3inches x 0.9inches.
