The SparkFun RP2350 Thing Plus is a highly capable wireless development platform designed to serve as the foundation for your IoT projects. Building on the RP2040 foundation, the RP2350 delivers higher processing speeds and expanded memory capacity, all the while working in tandem with the RM2 radio module in our standard Thing Plus form factor. Additionally, this board includes all of the hardware you expect from a Thing Plus, making it ideal for everything from local sensor nodes to remote, battery-powered devices!
Raspberry Pi's RP2350, at the core of this Thing+, is a unique dual-core, dual-architecture microcontroller that runs at up to 150MHz. This chip provides a unique setup that allows you to select, in software, which cores you want to run:
It's important to note that this isn't a quad-core MCU. At boot, you will need to select which two processors you want to run, allowing you to develop and test on two different architectures with a single board. The RP2350 also features 520kB of SRAM, two UARTs, two SPI controllers, two I2C controllers, and a USB 1.1 controller for host and device support.
To support demanding network applications and data-heavy tasks, this Thing+ pairs wireless connectivity with expanded onboard memory. This combination allows the board to efficiently manage complex operations while maintaining a steady connection.
This board is built using the SparkFun Thing Plus form factor, making it fully compatible with the popular Adafruit Feather footprint. It breaks out a selection of 21 GPIO pins from the RP2350, along with PTH connections to USB voltage (5V), regulated 3.3V, battery voltage, the RP2350 reset signal, and the voltage regulator Enable pin, to standard 0.1-inch spaced headers.
To make using the RP2350 Thing+ as easy to use as possible, we have equipped this board with several built-in features:
The RP2350 Thing+ is built for all developers. It has full software support for C/C++ using the Raspberry Pi Pico SDK, MicroPython, CircuitPython, and the Arduino environment, so you can choose the programming language and environment you prefer.
