Electron Plus software is built to work exclusively with our hardware; it is free to download and use with our products. As with most software, there will be continuous updates to add & fix features. Any and all feedback is welcome, and we will do our utmost to fix any problems in a timely manner. 

Our instruments use USB<>serial bridge IC’s from several manufacturers (FTDI and WCH). We suggest you download and install these drivers BEFORE plugging in your instrument. 

At present we test for and support Microsoft Windows 10 and 11 operating systems, however we regularly test on Windows 7/8. 

Note: In early 2022 we split our EPIC software into separate code bases so we can better manage our development stack, improve testing and make quicker performance enhancements & bug fixes. 

Note (30 November 2025, updated 1 March 2026): We have released a new version of EPIC, now called EPIC26, we will be updating this regularly daily as we enable features and sort bugs.
