Hello Fint,

My understanding is the 40mA is the maximum current per analog/digital pin can draw from the chip. In the DIY video the RX is connected to the 5v pin which is powered by USB and typically rated to 500mA minus the draw from chip, however with USB OTG this may also vary from host device as it may limit the current draw for USB OTG devices.

In my experience, I can power the RX5808 and a HC-06 Bluetooth module from the Arduino USB - 5v pin without any issues.

However the full schematic recommends powering from a dedicated 5v regulator connected to the Arduino 5v pin. You can view the schematic @ https://www.pidflight.com/pidflight-lap/build-your-own/

Hope this answers your question Smile

Cheers,
Christian

Thanks guys, all clear.
Got alle the stuff in now, Will be soldering soon.
Another question, does the rx need An antenna or does it work fine without even a SMA connector?

It's recommended to use the VRx without an antenna -- it works fine and generally less sensitive.

Finished it yesterday. Works great!
Thanks for the support.

Just trying to find the best antenna solution. Wondering what would happen if i remover the SMA connector.

Maybe a very stupid question but i would like to know if it's possible to make a race tracker on 2.4 GHz. This because we organize event for kids with stock e010's and it would be great if we could track there time through a lapp. This to give the kids a more competition feeling.
