Mini USB WiFi Module and Model 1 Pi

by ntynen on Sat May 28, 2022 10:17 pm

Hello,

I have a Raspberry Pi Model 1 running the latest Raspberry Pi OS (based on Bullseye).

Will the Mini USB WiFi Module work with this hardware?

Thanks,
Nicole

Which model of Raspberry Pi do you have? When you say model 1 does that mean the first release model from 2012? Here is a chart which might help me to confirm the device you have.

The USB port might not have enough power for the WiFi to work well. I've had to use powered USB hubs when working with some of the WiFi RTL chipsets to get them to operate at full power. Otherwise I suspect it will work fine with the OS being and earliest hardware releases of Raspberry Pi.

Thank you for confirming your model "Raspberry Pi Model B Rev 2".

That is an oldie, but a goodie.

The maximum current all USB peripherals can draw from the USB port is 600mA. By changing a value in the /boot/config.txt file, this current limit can be increased to 1.2A for all four ports.


Code: Select all | TOGGLE FULL SIZE
max_usb_current=1


I mention the current draw and max USB power since this module can draw up to 120mA of current.
