Everything Is On Its Way to Mouser for Fulfillment

Finally, the moment has come. I can now let you know that a shipment left our warehouse yesterday containing all crowdfunding orders and all existing pre-orders. It cleared export controls today and should arrive at Mouser's warehouse next week (if we get lucky and are quickly cleared through import customs). This update also touches on software and firmware development, ongoing manufacturing logistics, and an open source Automated Test Equipment (ATE) integration with Node-RED. Read the full update.

Fulfillment Progress

We are currently waiting on Mouser to initiate the pick up of five pallets. Stacked atop those pallets are all crowdfunded EEZ BB3 orders and all pre-orders that have been placed to date. We expect them to be on their way to Mouser by the end of this week, but we've pushed the estimated ship date for crowdfunded orders back to early September to make room for anything that might come up on the receiving end. Pre-orders should go out a week or two after that. Read the full update.

Everything Is Now Ready For Shipping!

We are finally in a position to announce that we have everything we need to fill all crowdfunding orders. The fifth batch of DCP405 modules arrived two days ago, so we now have enough for all of our backers! If we can quickly agree on shipping terms, the shipment could be on its way to Crowd Supply by next week. This update includes a brief status report on our software development efforts and on our progress toward CE marking. It also includes a warning to avoid the manufacturer that has been handling DCP405 assembly... Read the full update.

DCP405 Modules Are In

After a long break, the DCP405 modules have finally begun to arrive. The first (smaller) batch showed up this morning, and two larger batches will follow. We're getting very close, but we do not expect your BB3 to ship out from Mouser within the next ten days, so we've pushed our estimate back to early August. Read the full update.

Approaching Finalization

Apologies for the long delay since our last update. We are ready with four out of five modules and are now just waiting on the DCP405. But time flies, and estimates continue to shift, including our best guess as to when production will be complete. For now, we've pushed our estimated ship date to July 13th. This update includes a list of what we've been up to lately and photographs of the tested modules. Read the full update.

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.

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.

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.
