I meant to say 5ghz, not 5G mobile. I forgot about the congestion on the 2.4ghz band living out in the country because in general I somehow think that the device won’t feel faster with with the extra speed/bandwidth that bump would give.
Hi @maxmatteo,
That’s a cool module.
I checked and it appears that it uses two USB ports, one for Wi-Fi and one for Bluetooth.
To use both, in addition to installing the Wi-Fi module, you will need to install a separate PCB with a USB hub. This is what they do on their development kit.
You should be able to get it to fit, although no guarantees. There are a number of ribs that you have to avoid.
Another issue is connecting to the USB internally. There is a 4-port USB hub built in and currently all 4 ports are being used. Potentially, you can use the device / OTG port which has test-points exposed but then you won’t be able to use that port.
Our suggesting is if you are going to be hacking on the PCB then find a drop-in compatible Wi-Fi/BT module and replace the 2.4GHz module. You will also need to change the antenna and RF-Switch. The antenna has a 5GHz pin-to-pin compatible version. The RF-Switch may be a little harder to find in drop-in compatible IC.
Good luck if you try this and please let us know your results.
