Genuine Nano with Quartz Crystals. Replacing the Nano to remedy high frequency audio tone.
The official Arduino site says they are out of stock, however I found that the RobotDyn Nano ATmega328 (without headers installed) that has Quartz Crystals 12MHz USB and 16MHz ATmega328.
Without headers installed I can sacrifice the existing Nano without risking damage to the Radunio main PCB.
It is available on Amazon for $6.49. Free Delivery if you have Amazon Prime.
I just ordered one so I should be able to try it out replacing the current Nano on Tuesday before I head to Orlando for Hamcation. on Thursday morning.
