SparkFun Thing Plus - RP2040

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 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.
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 use 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.

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.
