Jupiter75%

Sleek, compact, and adaptable, Jupiter75% is a brand new custom keyboard design from Mu.Studio.

Jupiter75% is a compact 75% keyboard featuring bluetooth + USB-C dual mode connection ideal for different user scenarios.

Mu.Studio will be teaming up with DT.Heart to bring this board to life. DT.Heart is a newcomer to the hobby but they will set to introduce more cool products to the community.

Mumama from Mu.Studio posted renders of the design in geekhack some time ago and I would like to share some photos of the prototypes.

Current plan for GB is early July.

its really cool，i will join this gb:nerd_face:

Does the Bluetooth work with a metal case and metal plate?

6

Mind if I ask what is the QMK speaker that you are referring to?

7

The Bluetooth antenna will placed near a hold on the cases. I bet that helps. There will be more info about bt next week. The designer is planning on releasing a video of testing the bt functionality.

8

A special signal outlet has been made. It can help Bluetooth signal transmission

9

Sure, the code is documented here and it is implemented already for the clueboard LP and a few other boards. There are a few outdated videos out there that demonstrate the feature like this one.

10

What’s the range on it?

11

The prototype has been made and I doubt that this feature will be included. Interesting design tho

It’s Bt4.0 so the max theoretical range is 30m but it would be limited to your network interference(your phone, 2.4g wireless network, etc) but I think on the desktop it would be fine but not reliable if you want to use it as a sofa keeb that controls your TV.

13

QMK supports has support for speaker output for various beeps and sound effect. I’ve seen this implemented before on the Planck and it’s midi ‘piano mode’

14

Qmk official did not upgrade firmware brush mode，so this time its no qmk speaker

15

So many hot 75% coming up, 2019 seems like it’s going to be the year of the 75. If this had a blocked off f-row it would be absolutely perfect, but even like this it’s my top choice among the rest.

BT4.0 and ISO seal the deal for me, if the price is right I’ll be in for one!

Would love to see a render with GMK caps tho

16

the price will be good. Please look forward to it.

Just a heads up to anybody who might be watching this, the GB is now live on zFrontier!

I just joined for a black one.
