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.
