I’m using a different pcb designing program then eagle but upon uploading (SparkFun SAMD21 Dev Breakout) schematic for further inspecting, I have 2 components that I would like a little more clarity on. First one being the crystal, I know that it uses a 32.768kHz 3.2mm x 1.5mm 2-SMD package but as far as tolerance for frequency or any other details to pinpoint an exact model I am lost. Second component is the inductor (ferrite bead) that is used to suppress the high frequency noises coming from power supply. I can tell that it’s an 0603 package and is 30ohms impedance frequency but what filter type is it and what is the DC resistance value? Any help my way will be greatly apprecited, thanks!
Thanks for reaching out to us on this.
This might help with your first question…It looks like that uses the SAMD21G referenced in their data sheet https://cdn.sparkfun.com/datasheets/Dev … asheet.pdf (the middle column on 3rd page, 2nd page has more clock info)
Hope this helps, and wish you the best of luck in researching your project!
