Button included with pixracer

Hello

I am sorry to ask this but I could not find it anywhere. The pixracer included a button. What is it for and how does it work? What does it do exactly?

Also, it included the wifi module. I have read elsewhere that I am supposed to flash the firmware to it, is this correct? How is this done? I’m I supposed to connect it to a USB port in my computer somehow?

Thanks for your help!

Hello,
The button is the “Safety Switch”, you have to push it before arming.
The wifi module included is normally already flashed, so just try it.
