Seeduino STM32F405 Boards – Like Teensy, More Powerful
The Seeduino is an open source electronics platform. The board features a 32-bit microcontroller and a rich development environment, making it a perfect solution for engineers and hobbyists alike.The Seeduino has high speed (168MHz), more code space (1MB), and more available RAM (200KB+). They’ve also given it a whole series of rich new features like four serial ports, six PWM channels and 12-bit ADC. The dimension is same with Teensy V3.1/2, but more powerful.
