-Modular programmable bench power supply is based on [EEZ H24005](https://github.com/eez-open/psu-hw) project and introduces new digital control and better modularity by using EEZ DIB backplane based on [DIB v1.0 specification](https://github.com/eez-open/modular-psu/tree/master/DIB%20v1.0) that allows adding of new functions in the future (e.g. multi-channel power source, 2/4-quadrant power module, multi-channel temperature sensor module, data logger, switch matrix, digital I/O expander, function generator, data acquisition module, etc.). 
-It is work in progress and it's conceived to have the following components/modules:

+### Introduction
+
+EEZ Bench Box 3 (BB3) represents a new category of *modular* Test and Measurement (T&M) equipment. It provides 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](https://github.com/eez-open/psu-hw) power supply project ([OSHWA UID HR000001](https://certification.oshwa.org/hr000001.html)), which attracted many enthusiasts with its broad feature-set, rich user interface, DIY-friendliness, and fully open-source design. 
+It initially comes with two DC power modules (hence the name of repository *modular-psu*) and will be expanded with new T&M modules (e.g. multi-channel power source, 2/4-quadrant power module, multi-channel temperature sensor module, data logger, switch matrix, digital I/O expander, function generator, data acquisition module, etc.). 
+BB3 is made up of the following components:
+
+* _[BP3C](https://github.com/eez-open/modular-psu/tree/master/bp3c)_ EEZ DIB backplane with power output coupling capability of first two modules
 * _[AUX power supply](https://github.com/eez-open/modular-psu/tree/master/aux-ps)_ board with AC input protection, soft-start/power-up control, DC fan controller and +5 V / +12 V power outputs
-* _[MCU](https://github.com/eez-open/modular-psu/tree/master/mcu)_ board based on STM32F769IGT6 32-bit ARM Cortex-M7 as replacement for Arduino Due
-* _[DCP405](https://github.com/eez-open/modular-psu/tree/master/dcp405)_, 0 - 40 V / 5 A DC power source, an EEZ H24005 [Power module](https://github.com/eez-open/psu-hw/tree/master/Power%20board) variant (require an off-the-shelf fixed output 48 Vdc AC/DC power module)
-* _[DCM220](https://github.com/eez-open/modular-psu/tree/master/dcm220)_, dual sync buck 0 - 20 V / max. 4 A with current limit 
-* _[Bench Box 3](https://github.com/eez-open/modular-psu/tree/master/enclosure)_ metal enclosure for housing up to 3 modules with 4.3" TFT LCD. Dimensions: 290 (W) x 123 (H) x 240 (D) mm
+* _[MCU](https://github.com/eez-open/modular-psu/tree/master/mcu)_ board based on STM32F769IGT6 32-bit ARM Cortex-M7
+* _[DCP405](https://github.com/eez-open/modular-psu/tree/master/dcp405)_, 0 - 40 V / 50 mA / 5 A DC power source
+* _[DCM220](https://github.com/eez-open/modular-psu/tree/master/dcm220)_, dual sync buck 0 - 20 V / max. 4 A
+* _[Metal enclosure](https://github.com/eez-open/modular-psu/tree/master/enclosure)_ for housing up to 3 modules with 4.3" TFT LCD. Dimensions: 290 (W) x 123 (H) x 240 (D) mm
