SparkFun Thing Plus (RP2040)

The RP2040 contains two ARM Cortex-M0+ processors (up to 133 MHz) and features:

• 264 kB 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 C/C++ and MicroPython cross-platform development environments, including easy access to runtime debugging. It has a UF2 boot and floating-point routines baked into the chip. While the chip has a large internal RAM, the board includes an additional 16 MB of external QSPI flash memory to store program code.
