Expansion Board 3.0 Vin (3.5-5.5V) pin



  • Hi all,

    A quick question: is the voltage of the Expansion board 3.0 5V pin the same as the power supply voltage (3.5-5V) or is it always 5V, regardless of input? On the Expansion board 3.0 pinout, it's marked as 5V but on the LoPy4 pinout, it's Vin (3.5-5.5V).

    In other words, is the input voltage regulated in any way on the expansion board?

    Thanks!

    No. It's the same signal, just differently labeled. When connected to USB, you should see 5V at that pin coming from USB. Otherwise you can supply a xxPy device at that pin with input voltages from 3.5-5.5 V.
