Hi, according to the Welcome to Teensy 4.1 card that came with the board, there are two 3.3V. The one above A10 on the left is 3.3V while the one above A9 on the right is 3.3V (250 mA max). For the one on the left, what is the maximum current that it can provide to breakout boards? Is it better to use this one than the one on the right as it probably can offer more current? As for the Vin port, what is the recommended and maximum allowable current input in mA if I use 3.7V LIPO battery?
