Raspberry PI iC880A and LinkLab Lora Gateway Shield

ic880a-raspberry-pi's Issues

DHT 22 header rotation needed

The DHT header needs to be rotated 180 degrees so that when soldered on it does not clash with the ic880a PCB. At the moment it has to be soldered on at an angle.

DC/DC step down 3A link

Hello,

the first link for the 3A step down point to a fixed 3.3V version.

Code update?

Hi, As I understand to have this LED features I need to use old library libloragw v3.1.0 from 16.Nov.2015.
Do you plan to update this to v4.1.2?

GPS connection for iC880A

Hi,
thanks for your great work with the backplane. It is very versatile and great to use!
However, I am missing one feature: The support for a GPS module with PPS signal. It would be great if you can add a header for a GPS module (e.g. for a GN-801 GPS module) that connects the UART to the Raspberry Pi and the PPS pin of the module to pin 19 of the IMST iC880A. Currently I am modifying the board by myself, but it would be great if I can just add a header and connect the GPS module there.
I know there has been a discussion about the sense of this addon, but the GPS module is very cheap so why not adding it :-)?

Best regards,
Tim

Doesn't work with newer PIs

Maybe a note to the README that it won't work with newer PIs as they moved the Ethernet connector? Unfortunately I can't just dremel it out; would destroy PCB traces.

P.S. ignore the terrible soldering job, was years ago

Unclear License

Please clarify the license. From what I understand https://creativecommons.org/licenses/by-nc/4.0/ would fit your purpose.

All parts optional?

Do I need parts (except the connectors) if I just want to use it as connection between the rpi and the ic880a?

Using the board with RFM95 as a single channel gateway

So I tried to follow the soldering instructions:

Unfortunately i was unable to make the single chan gw working.

Some outputs:
