+# fpan-mxe
+This folder contains the frontpanel used when the esp32MX-E is used together with the pt3mx(or custom board) baseboard, and the RM2015S
+enclosure. This frontpanel is a standard PCB (1 or 2 layers), with black solder mask. By default, we get them manufactured using HASL(Hot Air Solder Level) surface finish. For a bit extra, you can get it manufactured with the ENIG(Immersion Gold) surface finish, which adds a premium look.
