Feature #3965: ICE40 based USB E1 adapter
Feature #3967: design a custom board for the ICE40 E1 adapter
find enclosure for ICE40 E1 board
Added by laforge about 5 years ago.
Updated over 3 years ago.
Description
I would recommend Fischer aluminium enclosures such as those of the AKG series.
In terms of the connectors:
- RJ45 for E1, obviously
- USB-B (I would actually go for full-size-B for robustness)
- SMA for GPS Antenna connection
Not sure if we need anything else. If there's a UART for debugging, we should of course go for the standard 2.5mm osmocom jack.
- Status changed from New to In Progress
- Assignee set to tnt
- % Done changed from 0 to 70
Primary candidate is SZOMK AK-C-B-37
I got a couple of sample unit and they look nice and I like the silicone "seal" around the end panel which make it non-slip. I'm also hoping they can do custom holes in front panel at a reasonably cheap price even for low qty (like 20 units or maybe 50). I'll get a quote as soon as I finalized the front panel.
Fall back is fischerelektronik.de "AKG 55 24 80 SA" which is nearly identical, just a bit less wide and shorter. I'll try to make sure the PCB can easily be adapted for both. (obviously not the exact same PCB but so that the layout doesn't have to be re-made from scratch if we need to change)

I think we can definitely go for MOQ-50 units, possibly even 100.

great, thanks.

The Fischer AKG was not suitable due to the constrained with. tnt did the full enclosure integration and prototyping with his primary candidate SZOMK AK-C-B-37
Note that if at some point we need to go back to the Fischer AKG, it shouldn't be "too" hard to fit it if we remove the support for the "GPIO" port of the front panel and mode the serial connector to the other side of the USB.
So it wouldn't be a full re-layout ...
