Hi there,

I went to a parts scavenging hunt through some of my old electronics gizmos that were waiting to be torn apart to find a 32.768 KHz crystal.

I found one and I'm going to solder it to PA00-PA01 pins of the ATSAMD21G mcu on JACK in order to make it more like the Arduino Zero and #HACK. In fact, the Arduino Zero core sets the main clock of the SAMD21 to the XOSC32 source. This will make JACK a HACK+ boards, to speak. We'll see what happens.

Cheers,

Mick
