Revising Estimated Ship Dates

We received an update from the company that will be supplying AC/DC converters for the BB3 peripheral modules, and it sounds like the parts we ordered will not be ready for shipment until March 20th. Unfortunately, that means we've had to push our estimated ship dates back to May 1st. This update includes a brief summary of our progress since we last checked in. Read the full update.

Two New Peripheral Modules (and More Delays...)

The main news for this update is that our TFT display supplier in China has announced an additional three to four week delay due to the Coronavirus outbreak. Unfortunately, they cannot yet provide a delivery estimate or let us know when production will stabilize. In the meantime, we have designed two new peripheral modules, which are now ready for prototyping. Read the full update.

Thank You & Protection Mechanisms

Martin and I want to thank all of the backers who have helped us reach our funding goal. We believe that BB3 will meet your expectations. In this update we’d like to present various protection mechanisms that are important for every sourcing instrument, including EEZ BB3 when it's equipped with power modules. Read the full update.

IoT infrastructure features and OSHWA certification

EEZ BB3's IoT functionality began with SCPI support. We then gave EEZ Studio the ability to serve as a cross-platform automation hub for SCPI-enabled instruments connected over Ethernet or through serial-over-USB. Finally, to round out this IoT feature set, we have added MQTT support. Finally, we are happy to announce that EEZ BB3 is now OSHWA-certified as open hardware. Read the full update.

MicroPython Arrives on BB3

We now have a functional implementation of MicroPython running on the STM32F7 MCU at the heart of BB3. This update describes how you can run MicroPython on your BB3 and includes a video demonstration of a basic diode tester. Read the full update.

Power Output Coupling & Tracking. (And the Announcement of Our First Stretch Goal!)

The EEZ BB3 chassis comes with a backplane that distributes data and control signals. That backplane also provides four relays that support easy, firmware-level coupling of power outputs without the need for external wiring. This update includes a video that describes BB3's power output coupling functionality. It also announce our campaign's first stretch goal! Read the full update.

DCP405 Module - Advanced Features

This update includes a short video that introduces advanced features of the DCP405 module that are not present in the basic DCP405B. That include remote sense, a down-programmer, remote programming, and fast OVP. Read the full update.

Thank You & Data Logging Automation

Support for this campaign has been incredible. Thank you! Keep reading to learn more about, and to see a demonstration of, EEZ BB3's data logging features. Read the full update.

Our Campaign is Live!

It's been a long time since we decided to make the H24005 more flexible and more powerful by giving it a larger screen, an upgraded MCU, and a modular design built around a DIB v1.0 backplane capable of receiving up to three DC power source modules. We are confident that BB3 will live up to that promise. Read the full update.

Support EEZ Studio Development

EEZ Studio is a cross-platform free and open source BB3 development environment but also attractive SCPI controller that is used to access many T&M devices using SCPI commands. Its development and support cost us money and your donation will help us to keep it alive and kicking.

BB3 Enclosure & Bare Boards

A BB3 enclosure kit with a wire harness, nuts and bolts for the three core modules, a 4.3" TFT touchscreen display, an encoder knob, and an 80 mm fan. Includes a set of bare PCBs for building the three core modules (AUX-PS, MCU STM32F7, and BP3C DIB 3-slot backplane) as well as PCBs for building one DCM220 two-channel peripheral power module and two single-channel peripheral power modules (either the DCP405 or the DCP405B, as they can be assembled using the same PCB). Suitable for builders with the necessary skill, time, and patience.


$350

BB3 - Starter (Without Peripheral Modules)

A BB3 enclosure kit without bare PCBs but with fully-assembled core modules (AUX-PS, MCU STM32F7, and BP3C DIB 3-slot backplane). The Starter provides an environment for experimenters who are willing to build their own modules or who want a specific BB3 configuration (such as a six-channel BB3).


$650

BB3 - Two Channel (Full)

A BB3 starter kit and two full-featured DCP405 single-channel (40 V, 5 A) peripheral power modules, including an AC/DC power module for each. A two-channel programmable power source with advanced features: remote sensing, remote programming, a down-programmer, and additional OVP (with crowbar).


$750

BB3 - Four Channel (Full)

A BB3 starter kit, two full-featured DCP405 single-channel (40 V, 5 A) peripheral power modules, and one dual-channel DCM220 peripheral power module. Includes all three necessary AC/DC modules. This is the two-channel full kit, expanded to include two additional programmable power sources.


$179

DCP405 One Channel Module (Full)

A full-featured DCP405 single-channel (40 V, 5 A) peripheral power module with remote sensing, remote programming, a down-programmer and crowbar OVP. Includes an AC/DC module.


$125

DCM220 Two Channel Module

A DCM220 dual-channel (2 x 20 V, 4 A) peripheral power module and its AC/DC module.


$59

Cable Set

Two pairs of high quality, silicone, color marked (black-red), 1 m connecting cables; a pair of clip-on probes; and a pair of insulated crocodile clips.
