SparkFun Thing Plus - RP2040 ARM Dev Summit

The SparkFun Thing Plus - RP2040 is a low-cost high performance board with flexible digital interfaces featuring the Raspberry Pi Foundation's RP2040 microcontroller. Besides the Thing Plus or Feather footprint (with 18 GPIO pins) the board also includes an SD card slot 16MB (128Mbit) flash memory a JST single cell battery connector (with a charging circuit and fuel gauge sensor) an addressable WS2812 RGB LED JTAG PTH pins four (4-40 screw) mounting holes and our signature Qwiic connector. The RP2040 contains two ARM Cortex-M0+ processors (up to 133MHz) and features: 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. While the chip has a large amount of internal RAM the board includes an additional 16MB of external QSPI flash memory to store program code.
