SparkFun Electronics Thing Plus – STM32 offers power and precision with a 32-bit ARM® Cortex®-M4 RISC core. The Thing Plus provides a DFU bootloader for uploading code and incorporates an extensive range of enhanced I/Os and peripherals. The STM32 Thing Plus utilizes the handy Qwiic Connect System, which means no soldering or shields are required to connect it. The STM32 Thing Plus delivers an economical and easy-to-use powerful development platform designed for a minimal working space.

The SparkFun Thing Plus – STM32 STM32F405 Processor is based on the high-performance ARM® Cortex®-M4 32-bit RISC core and can operate at a frequency of up to 168MHz. The Cortex-M4 core features a floating-point unit (FPU) single precision, supporting all ARM single-precision data-processing instructions and data types. Additionally, the core implements a complete set of DSP instructions and a memory protection unit (MPU) which enhances application security.

In addition to the USB interface and Qwiic connection, the STM32 Thing Plus provides a 3.3V regulator and LiPo charger and 16MB of Flash and microSD slot for expandable memory.
