 # pt3mx
 This folder contains a baseboard for the esp32MX-E board. It is designed to be used with raised 2x7 and 2x10 male
 pin headers(standard 0.1" = 2.54mm spacing). We use 14.5mm raised headers, and also have 14.5mm high PCB spacers
 available. It fits into the Hammond RM2015S enclosure. The "fp_pt3mx" front panel can be used with the RM2015S
 enclosure.
