 === Ordering PCBs ===
   * Follow the instructions to generate Gerbers at your PCB house, e.g. [[https://jlcpcb.com/help/catalog/180-PCB-Files-Preparation|JLCPCB PCB Files Preparation]]
-  * Default 1.6mm 2-layer PCB settings should work well
+  * Default 1.6mm 2-layer PCB settings should work well, this PCB passes DRC based on JLCPCB specifications (other than the silkscreen of XIAO module being clipped by the PCB edge)
   * PCBA: I used [[https://github.com/bennymeg/Fabrication-Toolkit|JLC PCB Plug-in for KiCad]] to generate a BOM and CPL file compatible with JLCPCB PCBA
