Hi,
I'm creating a circuit with an arduino clone (https://moderndevice.com/product/bare-bones-board-bbb-kit/) and an LED driver (MM5451, pdf datasheet: **broken link removed**). Currently I'm powering everything via USB FTDI cable attached to the arduino clone.
On the FTDI pins attached to the arduino, I see 5v. However, on the other side of the arduino, the +5V/GND pins actually report ~3.5V. Now, the IC datasheet says that it needs "4V-11V" as supply. Does this mean I can't power the IC with the "remaining" voltage?
How are issues like this normally addressed in circuits? My feeling is that if I power the circuit with a higher voltage (non-USB) source, everything would work?
I've also come across "voltage multipliers," but I don't know enough about them to know if this would help me as well.
Thanks!
