Developers, electronic enthusiasts and makers searching for a modular, open source test and measurement chassis may be interested in the EEZ Bench Box 3 created by Envox. The modular system expands on the previous systems and offers users a “new category of modular Test and Measurement (T&M) equipment” say its creators. Check out the video below to learn more.
The EEZ Bench Box 3 has been created to provide “a complete open-source hardware and software framework that bridges the gap between – and combines the best features of – DIY hobbyist tools and professional benchtop equipment. BB3 was inspired by the EEZ H24005 power supply, which attracted many enthusiasts with its broad feature-set, rich user interface, DIY-friendliness, and fully open-source design. BB3 will initially ship with modules that provide the same functionality as the H24005, but those modules will come slotted into a device that delivers improved modularity, greater capacity, more processing power, an easier-to-use interface, and enhanced flexibility, all in a compact form factor.”
The system is now available to preorder as a barebones enclosure from $165 or without peripheral modules from $350 with worldwide shipping expected to take place during May 2020.
Features of the EEZ Bench Box 3 modular, open-source test and measurement chassis include :
– Modular architecture based on the EEZ DIB v1.0 specification
