STAMP IO
Description
STAMP IO is an IO expansion board based on STM32F030 main controller, using I2C communication interface, providing 8 IO expansion. Each IO supports independent configuration of digital input/output, ADC, SERVO control, RGB LED control modes. Suitable for multi-channel digital/analog signal acquisition, and lighting/servo control applications.
