Wow! Thank you again.

I am so impressed by your detailed, expert, and helpful response.

Thank you so much!

So just to be clear, there was no design change in the 12V boost from v1.1 Rev A to v1.1 Rev B, just a correction in the resistor used during manufacture? Were any other aspects of the design changed at this time?

If so, maybe it would be helpful to add some Rev B documentation to the “Changes” list shown on this page: https:/…[Read more]

Hello there,

I have a question about the 12V power on Mayfly V1.1. Among the changes listed in the rev A design (https://www.envirodiy.org/mayfly/hardware/details-and-specs/) it states that the “12v boost circuit… can now source up to 100mA, although the nominal output voltage is ~11.3v”.

I am curious why the nominal output is 11.3…[Read more]
