From the project
EEZ Bench Box 3 Plus (BB3+) Modular T&M chassis
EEZ BB3+ was conceived as a successor to the BB3 project, which would bring a number of modifications and improvements. The following modifications are planned:
[x] Combining 3 existing core modules (power supply, MCU and backplane) into a single mainboard [x] Enlarge TFT touchscreen from 4.3" (480x272) resistive to 5" (800x480) capacitive [x] Increase fan size from Ø80 to 92 mm [x] Single main power rail +12V (45/60 W) [x] Introducing half width modules and increasing the total number of modules from 3 full-width to 5 half-width (or two 1½-width) [x] TFT Display PCB with 4 user switch/hot…

BB3plus USB hub test: common questions
What microcontroller does the BB3plus USB hub test use?
The BB3plus USB hub test is built around the STM32G071R8T6, from the STM32 family.
How big is the BB3plus USB hub test PCB?
The BB3plus USB hub test measures 144.5 × 103 mm, has 4 copper layers and is 1.605 mm thick.
How many components are on the BB3plus USB hub test?
223 components, from 75 distinct parts. The full bill of materials is listed on this page.
Where can I download the BB3plus USB hub test design files?
From the eez-open/eez-bb3plus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BB3plus USB hub test design in my own project?
