EEZ Bench Box 3 Brings Modular Case for T&M Programmable Power DC Sources




Croatia-based Envox Experimental Zone has designed a new modular version of the EEZ DIB (DIY Instrument Bus) test and measurement system, which was inspired by the EEZ H24005 programmable bench power supply.

“The EEZ Bench Box 3 (BB3) represents a new category of modular Test and Measurement (T&M) equipment. It provides a complete hardware and software framework that bridges the gap between — and combines the best features of — DIY hobbyist tools and professional benchtop equipment.”

Under the hood, the Bench Box 3 packs numerous features and specs, which include an STM32F7 Arm Cortex-M7 MCU, full-range autoswitch AC input (115/230 VAC), front panel AC power switch, 4.3-inch TFT touchscreen display (480 x 272), and a front panel bootloader switch for the main MCU (firmware upload via USB DFU). It is also equipped with an incremental encoder and user-defined switch, USB 2.0 OTG, 10/100 Ethernet port, and four power relays for coupling various power outputs.

The Bench Box 3 provides dedicated full-duplex SPI and dedicated bootloader control for each module (firmware upload via UART, SPI, or I²C), a speed-controllable low-noise 80mm cooling fan, and can be remotely operated by 300+ SCPI commands using the company’s EEZ Studio software suite or similar SCPI controllers.

Envox Experimental Zone is set to launch the Bench Box 3 on Crowd Supply in the coming days or weeks, and backers will be able to configure their model to their preferences, which entail bare PCB options, a custom metal enclosure, and a choice of several Core Modules and power modules. There’s no word yet on price or when the campaign will go live; however, those interested can sign up on EE’z crowdfunding page for updates.
