Test a Lilygo T Beam.

Lilygo 2.4GHz is somewhere down the road. Eager to test SX1280 with PA. But I would like to test other TTGOs as well.

the USB-C port provides 5V, the board runs at 3.2v, so there is power loss stepping it down cause it is used to charge a battery. To get true readings you must measure the power draw from a battery instead of the USB-C port since it is meant to be used that way. On repeater mode at power save mode i've gotten readings as low as 13mA on idle and 105mA when sending messages.

I have repeaters last 4days on a 2000mAh battery which would be impossible with the readinds you're getting from that test.

I want to thank you for sharing your thoughts. There is more than one to reach a conclusion. Which way I chose or someone else chose depends upon how accurate results we need and willingness to spend time and money on it. The tests I have performed are not research level tests going as basis for scientific thesis. They are go people doing it as a hobby. So charging reading was taken with charging on - charging off while keeping all other things almost the same. 2) As you have mentioned that you were using power save mode, these reading will not match reading shown in the video as I was not using power save but trying to emulate normal use. 3) I am really happy that you are experimenting with these devices and sharing the results.
