Now in beta: USBC adaptor for DE1

Provides a USBC plug in the back of your DE1 espresso machine. Compatible apps, such as Streamline (more coming soon) can use USBC instead of Bluetooth, to connect to your DE1 and Half Decent Scale.

A hub can be used to let your app talk to multiple USBC devices.  The Streamline app supports the USBC feature (the Decenza app likely will soon).

Here is the USBC adaptor mounted on a DE1XL (on the top right of the photo) as well as a Belkin USBC hub, which keeps the connected Samsung tablet charged and also connects the Streamline app to the Half Decent Scale.  The DE1XL back panel, once installed, completely hides all this.

Bluetooth can continue to be used as long as no computer is plugged into the USBC port.

Use of the DE1 USBC adaptor with Android requires a Samsung tablet and a compatible powered USBC hub. We have tested and found that most USBC hubs are not compatible: only hubs advertised as "Macbook Pro USBC dongles" worked reliably. Also: Decent is working on a 4 port hub enabled version of our USBC adaptor.  Desktops (Mac, Windows, Linux) do not have this limitation.

A number of apps plan to support USBC connectivity. Decent's own Streamline App already does, as does Kulitorum's Decenza app and the current de1app intends to as well.

To install the USBC adaptor, you will

  • remove your DE1 back panel,
  • unplug the bluetooth chip,
  • plug the USBC adaptor into the now-empty socket,
  • plug the bluetooth chip into the socket of the Bluetooth adaptor.
  • put the back panel back on
  • screw the USBC case into the mounting point

    This is a limited 'beta test' run of this new accessory.  We only have 30pcs built, as of today. We can build another 20. Then it'll be a few more weeks before we can build 50 more pieces (we're awaiting all the cases).  Assuming a smooth beta cycle, we'll then order plenty more of these as we come out of testing in a month or two.
