The Controllino range is composed of three models – the Mini, Maxi and Mega – each of which is aimed at meeting different levels of application requirement and complexity. All models, developed and implemented using the Arduino open-source platform, are based on the ATmega microcontroller from Atmel and have a clock speed of 16 MHz.

Key features include a direct processor contact with 4000 V ESD protection across all pins, a range of interfaces including SPI, I²C, RS-232, RS-485, and an internal real-time clock (RTC) which can be switched on and off. A front-panel USB port supports simplified external programming.

The Controllino Mini offers a multitude of different inputs and outputs (6x relay outputs, 8x analog / digital inputs and 8x digital outputs) in a compact package measuring 94,5 x 59,4 x 36 mm. The Maxi offers greater flexibility (10x relay outputs, 12x analog/digital inputs and 12x digital outputs) with the addition of an Ethernet connecter and a second UART interface. The highest specification unit is the Mega, which is capable of handling a current of up to 30 A and offers 16x relay outputs, 24x analog / digital inputs, 12x high side switch digital outputs and furthermore 12x half-bridge digital outputs.
