• Description
• 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 d 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.
• The SparkFun Qwiic Connect System is an ecosystem of I2C sensors, actuators, shields and cables that make prototyping faster and less prone to error. All Qwiic-enabled boards a common 1mm pitch, 4-pin JST connector. This reduces the amount of required PCB space, and polarized connections mean you can't hook it up wrong.

• 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 beca 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.
