The Modular Modulo System
What's this... another modular maker kit? Correct, the Modulo system made by Modulo Labs consists of a series of circuit boards that plug together and can work in both the Raspberry Pi and Arduino environment. Each of the boards has its own built-in an ATtiny841 controller which interfaces to the sensor or output device on the board and handles communication with the main controller board which is fitted with an ATmega32U4. The boards plug neatly into the ‘Modulo Base Unit’. A Spark Base option allows the Spark Core, Arduino-compatible Wi-Fi development board to be substituted for the main controller board.
