[GB] Promenade - 60% Ortho pcb the takes ergodox keycaps (Boardwalk clone)

(1/3) > >>

Narf:
Promenade

This is an independent remake of my favorite keyboard layout: the Boardwalk. I added some features that I wanted in my own boards. The main additions/changes are 3u/6u spacebar support, 1.5u default center column instead of 1u*, a jst connector for a daughterboard, and gummy o-ring cuts around the edge.

Features:
* Atmega32u4
* Kaihl Hotswap
* ESD Protection
* RGB Underglow
* Edge cuts for some o-ring boards*
* JST connector for C3UDB
* Breakout pins
* 6u/3u Spacebar stabilizer holes added, 2u and 7u spacebars also supported
* 1.5u center mods (*with hotswap footprints for 1u columns)
* PCB and FR4 plates with be black and 1.6mm thick
* QMK powered with VIA support
* Optional USB-C port or edge cut for Bakeneko V3 mounting point*The 1u version will require some switch legs to be trimmed if using 5-pin switches for the center columns.
Both the USB version and DB version will have a JST socket.
Since the key switches on the Promenade are a bit farther from the edge of a 60% compared to a traditional staggered 60% pcb, gummy o-rings may not provide get an adequate friction fit. To try to alleviate this issue there are matching M2 holes on the PCB and FR4 plates where standoffs can be inserted to stretch the o-ring.
7u and 6u spacebar layouts can be clip in stabilizers, but 3u and 2u spacebars should use screw in stabilizers due to the stab holes overlapping slightly.

I am also making a solder version using an RP2040 that will have way more layouts and encoder support. The solder version GB will be launched after HS version GB is finished or nearly finished.

Mr Chrome:
Ordered! Aus shipping was brutal but what can ya do, I needed one ;-;

killchain:
Good job, nice to see this happen. I was also a bit desperate because I've been wanting a Boardwalk for some time, but never got the chance to catch it in stock. I'll make up my mind about 1U/1.5U and order. International shipping is indeed a bit expensive, but oh, well...

Just curious - any particular reason for the plates to be 1U/1.5U specific? I've seen other plates made to be interchangeable (just like the bottom row is here). Is it because FR4 is more flexible and would give too much with larger cuts?

kidviddy:
I'm very excited for the upcoming Soldered version of this board, but looking at the previews under the "Solder version layouts" section I don't believe my current layout (which was possible on the boardwalk) is supported. You say that the soldered version is still being designed... please could you consider the following layout when you do so? It's basically a pure ortho layout but with an off-centre 2U space bar beneath the B and N, and even though it's nothing fancy and it's a bit weird, for me it's just the perfect layout—so I was distraught to see the Boardwalk go! If you can manage to make it work on the Promenade I will definitely be in for a couple :)

Hiding the image behind a "read more" tag so as not to clutter up your GB thread too much... please let me know if this would be better suited to the IC thread or elsewhere.

Is there a list of readily available 60% cases that are 100% known to be compatible with this PCB and plate with no expected modifications? That would be very helpful info for potential buyers.
