SparkFun Thing Plus - RP2040

SparkFun Thing Plus RP2040 開發板 是一款低成本，高性能的主板，具有靈活的數字接口，具有 Raspberry Pi Foundation 的 RP2040 微控制器。 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.

• LEDs:
  • PWR - Red 3.3V power indicator
  • CHG - Yellow battery charging indicator
  • 25 - Blue status/test LED (GPIO 25)
  • WS2812 - Addressable RGB LED (GPIO 08)
• Four Mounting Holes:
  • 4-40 screw compatible
• Dimensions: 2.3" x 0.9"

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

1. Note: GPIO 08 is not included in this count, as it passes through the WS2812 addressable RGB LED first. GPIO 07 and GPIO 23 are counted as a single GPIO because they are tied together.

2. Note: The GPIO pins are programmable so you can reconfigure the pins! Check out the RP2040 datasheet for more information on the GPIO functionality.
