A Real-Time Clock & Other New Features

by Igor Levkov

Use Omega2+ Expansion Dock for Real-Time Applications

We have added a precise real-time clock (DS3231) and a battery holder (for CR1220 batteries). Most single-board computers lack a built-in real-time clock (RTC) module with independent power, which makes them difficult to use for scheduled tasks without constant access to current and an Internet connection.

You can find an example of how to use the real-time clock with Python on GitHub.

Improved Reliability & Convenience

In addition, we have improved the board’s ESD protection, added mounting holes, and replaced the on/off jumper with a power switch that should be easier to use.

The PCB’s updated dimensions are: 5.9 x 8.4 cm

We are planning additional improvements, as well, including the addition of a USB Type C connector in place of the micro-USB port!
