Is it power you seek? With a 32-bit ARM Cortex-M4F MCU, the SparkFun SAMD51 Thing Plus is one of our most powerful microcontroller boards yet！ The SAMD51 Thing Plus provides you with an economical and easy to use development platform if you're needing more power with minimal working space. This Thing even comes flashed with the same convenient UF2 bootloader as the RedBoard Turbo. To make the Thing Plus even easier to use, we've moved a few pins around to make the board Feather compatible and it utilizes our handy Qwiic Connect System which means no soldering or shields are required to connect it to the rest of your system！
The ATSAMD51J20 utilizes a 32-bit ARM Cortex-M4 processor with Floating Point Unit（FPU）, running up to 120MHz, up to 1MB of flash memory, up to 256KB of SRAM with ECC, up to 6 SERCOM interfaces, and other features. In addition to the USB interface and Qwiic connection, a The SAMD51 Thing Plus provides a 600mA 3.3V regulator and LiPo charger.
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.
