STM32 Stick Development Board

The STM32 Stick is a powerful development board in a breadboard compatible form factor, giving you 40 GPIO pins to work with. It uses the STM32F411RET6 running at 100MHz, with 512KB of flash memory, and 128KB of SRAM. The microcontroller comes with the DFU bootloader, which makes uploading code easy and allows the board to act as a HID device. 28 of the 40 I/O pins are PWM capable, and 16 have ADC support. There are also many communication peripherals available on pins including UART, I2C and SPI.

The high amount of I/O pins allows you to connect many different devices like sensors, keypads, displays, and motor drivers with extra to spare. You can also solder on a 208mil SOIC-8 SPI flash memory chip, which is great if you need to store files or data. You can easily program this board in the Arduino IDE using our Circuitneato ARM Boards package based on STM32duino. The board can be powered through the USB-C port, or with up to 24V on the Vin pin. Power can be safely connected to both at the same time because of the auto power select diode. The 3.3V linear regulator can output up to 500mA, and has a ~0.5V dropout voltage. The board can also be powered through the 3.3V pin only if a regulated 3.3V power supply is used.
