Is 1A enough to run Reach and 3dr radio?
Toying with the idea of using a PowerBoost from Adafruit .
I think that is enough. I use 10000mAh. But not adafruit…
Reach is rated to max 500mA consumption https://docs.emlid.com/reach/electrical-specs/
Not sure what 3d radio use…
Just a powerbank. I think we need only 5V and about mAh, bigger mAh longer time we get.
