Harald Welte dcad3c6b6a rj45_jumper_box: Add OSWH + sysmocom logo; final v2 as ordered 2023-01-20 16:38:05 +01:00
Harald Welte 561c824219 rj45_jumper_box: Connect shield of two connectors 2023-01-20 10:46:32 +01:00
Harald Welte b625dbf06b rj45_jumper_box: Use different RJ45 jack; both on top layer 
The original design (one RJ45 on top, one on bottom) was easy to route
but was difficult to handle. Let's swap both connectors to top, and use
a low-cost Chinese RJ45.

Harald Welte 7b4ddba001 initial check-in of bgt-keystone project 
This adds a 3U component carrier module into which you can mix and
match keystone modules as needed.

Martin Schramm fa5b17a0bd ngff-cardem: update schematics 
This includes now the GND for OsmoSer conn.

Martin Schramm f0f029afd5 ngff-cardem: connect OsmoSer's GND to GND (solves SYS#5514) 
This change somehow didn't make it upstream though committed as
bf211d3; so recreated.

Harald Welte e039fe1590 xhfc-breaout: Conncet SPI_INV to GND 
This was missing from the v1 design. SPI_INV must be tied to either high
or low to select the SPI clock polarity.  It was tied to low by manawyrm
in his manual rework, so let's reflect this in the design accordingly.

Harald Welte b76fb674e1 Add schematics + PCB layout for a simple AMR break-out board 
AMR (Audio Modem Riser) is a standard for pluggable boards with
audio codecs to connect to the AC97 interface of mainboards dating
to the late-90ies / early 2000s.

The idea of this break-out boards is to be able to interface such a
modem riser card with a microcontroller or FPGA, basically using them
as a digital interface to analog phone lines for softmodem development
as part of osmocom retronetworking.
