HubPiWi Blue driver working

September 26th, 2016

It has been a while since our flagship HubPiWi blue has been running successfully at kickstarter. For that last one month we did not post any update on it, and the main reason for this has to do with the driver for the rtl8723bu chipset that is not natively built in the current kernel of raspbiab and therefore does not work out of box.

I had been in touch with Matthew Dipple who had originally integrated the rtl8723bu driver on an earlier version of Raspberry Pi Zero. So I requested him to take a look at the HubPiWi Blue and see if he could get it working with the current version of the raspbian.

After initial hiccups with his hardware setups, yesterday ( 9/26/2016), he reported that he was finally able to get the driver working on the HubPiWi Blue !!! Matt took the pain of writing down all the details and I will direct you to his blog with details of the steps involved in his blog - HubPiWi Blue Drivers on Raspbian Jessie

In next few days we will be testing my HubPiWi blue for stability with these new drivers. If everything goes well, the orders for the manufacturing of about 1000 HubPiWI blue will be placed ( by Oct 1st week). The requirement from the Kickstarter itself is for about 700 units. We expect the preorders for the HubPiWi Blue to be of the order 300 after the end at kickstarter and start of shipping. If you miss pledge at kickstarter, you will have the opportunity to order it at Reference Designer website.

Stay tuned for more updates.


HubPiWi Blue - USB Hub, Wifi and BT for Pi Zero

August 27th, 2016 is glad to announce the launch of HubPiWi Blue - a HAT for Raspberry Pi Zero. The HubPiWi Blue extends three USB Ports, a Wifi and a Bluetooth on Pi Zero, while not requiring any soldering on its 40 Pin Connector.


The project has been posted on kickstarter and has crossed $5K at the time of writing.

The HubPiWi builds upon the success of HubPixed and HubPiWi - both of which are selling at ebay and referencedesigner. The HubPixed is also selling on amazon. The Hubpixed and HubPiWi were released for Pi Zero 1.2 as well as 1.3. However, since there is no new manufacture of version 1.2, we are not releasing HubPiWi Blue for version 1.2 or earlier.


HubPiWi production batch arrived - up and Running

June 24th, 2016

Today we received the production batch of the HubPiWi - a total of 300 of these. The production batch was ordered in two versions - 100 of these are for Pi Zero 1.2 and earlier and 200 of these are for Pi Zero 1.3 or earlier.

If you do not know, Pi foundation changed the design of Pi Zero and added the Camera Connector on it. Not known are other changes, and which affected the hub based products from Reference Designer - are the locations of the test points for 5V, Ground and USB+, USB- Pin Pairs. These test points were used to extend the connections to the Hubpixed and HubPiWi products of Reference Designer. It means the the Hubpixed and HubPiWi are no more interoperable between Pi Zero 1.2 and 1.3.

The HubPiWi comes in two flavors. Most of us who have purchased it after May 28th more likely need HubPiWi 1.3.

For now we just tested the HubPiwi 1.3 and is looking great. The Signal Strength of Wifi looks great and browsing was a breeze. The shipping will first start with US Customers. We also have a lot of Pre Orders and these will be shipped on first come firs served basis.

We expect that most of the US backers at kickstarter will receive HubPiWi by the end of next week. International backers should start getting these in the next week.

Here are some pictures of HubPiWi 1.3 from production lot.

Raspberry Pi Zero 1.3 releases - Adds Camera

May 16th, 2016

Update on the Hubpixed and HubPiWi

We took a closer look at the test point arrangement ( See the picture below). It looks like the position of the test points PP22 an PP23 ( for USB+ and USB-) has not changed. However, the position of PP1 has shifted a bit back.

So it looks like we will have to keep two versions of Hubpixed and HubPiWi - one that supports version 1.3 and one that supports the earlier versions. Stay tuned.

Original Post

The big news is the release of Raspberry Zero 1.3 that adds a Camera opening up a whole new possibility for enthusiasts. For example you can mount it on your door which will send you a picture of the person as soon as he presses your ring.

For reference Designer, the key question was - whether two of its products Hubpixed and HubPiWi will continue the to work. This is the question Ian asked

New Pi Zero with small physical changes to board. Will this still work with new version ?

To clearly answer the question, I will need the newer version in my hand. Unfortunately, when I checked the stock at Micro Center and other places, there was none. So I have to rely upon the information available now. Fortunately, I saw this rear picture of the Pi Zero 1.3.


If you look at the position under the two USB Micro connectors, these "seem" to be at the same position as the earlier Pi Zero. There seem to be little reason the position of these 4 test points will change, unless they run out of space routing the traces for the Camera Connector.

So, my answer as of today is - that the Hubpixed and HubPiWi "should" continue to work with the newer Pi Zero 1.3. I am heading ebay or at any other place to get hold of the Pi Zero 1.3. I will confirm the answer, as soon as I get these.

In the meantime look at the HubPiWi at kickstarter -
