I would like to use a shield that commubicates via i2c so 3.3v is ok, but it also has some isolated DC/DC converter that needs 5v…
i have looked at the schematics but found no “elegant way” of getting 5v from USB
any idea ?
Unfortunately, there’s not a elegant way of getting the 5V of the Mbili directly. You can ‘tap’ the 5V by, for example, soldering a cable to one of the pins of the slide switch (but this is a bit ‘hacky’).
Could you share which shield you are using and how you are connecting this to the Mbili?
