omega:TWO is an affordable industrial multipurpose 32bit microcontroller board, which supports MicroPython programming.
The comprehensive suite of STM32 development tools is also supported for traditional C/C++ programming.

Board overview


omega:TWO combines industrial hardware with the ease and speed of programming of MicroPython. This allows engineers to implement prototypes and products in a fraction of the time required for traditional C/C++ based development.

Key features:

  • Runs MicroPython out of the box

  • Provides common industrial communication interfaces, such as Can Bus and RS422/RS485

  • Twenty 12/24V opto-isolated digital inputs

  • Twenty 12/24V outputs with up to TBD A peak output capability (high-side switches)

  • A microSD card slot to store large amounts of data, such as for extensive datalogging

  • A battery-backed real time clock keeps track of the datetime also after power cycles

  • Wide supply input voltage range of 6V to 30V

  • The board can also be supplied directly through the USB-C connector for ease of use while developing

  • Firmware updates are possible

omega:TWO is suitable for a variety of industrial and research applications, such as:

  • Programmable Logic Controller

  • Rapid prototyping

  • Control systems for test setups

  • Signal/subsystem simulators

  • Data logging
