AVCC regulator module

AVR module both regs have to measure 3,4V?

Or so. Both sides of the AVCC share a common voltage reference. The ES9018 can tolerate up to about 3.8V for Avcc, and the module outputs between 3.4V and 3.6V, which gives the Buffalo slightly better analog performance.

Thanks for the input Brian, my both sides of the AVCC measure 3,45V🙂
