Hello, I have reviewed the posted crystal guidelines and I believe this layout adheres to the PJRC recommendations. Would anyone offer criticism before I send the board to the fab house? Thanks!
Notes: Crystal is 344-NX3225SA16MHZB3; this is a 2-layer DIY Teensy LC (MKL26Z64VFT4) project
"The crystal should be located close to the MK20 chip. A ground plane should be placed underneath the crystal. If using a 2 layer PCB design, the ground plane for the crystal should NOT make any other connections to ground, other than the crystal case ground, capacitor grounds (if adding extra capacitance) and to the ground pin next to the crystal pins."
