omega:TWO

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

_images/omegatwo_overview.png
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.
The board has a very wide-range supply input of 6.5V to 70V.
Twenty 12/24V opto-isolated digital inputs.
Twenty 12/24V outputs with up to TBD A peak output capability (high-side switches).
Common industrial communication interfaces such as Can Bus and RS422/RS485 (half-/full-duplex), are also provided.
A microSD card slot adds the possibility to store large amounts of data, such as for long-term logging.
A battery-backed real time clock keeps track of the datetime also after power cycles.
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

  • Data logging

  • Signal/subsystem simulators
