// "EVAN" desk nameplate molecule. 96 x 44 mm, USB-C powered from the
// EAST (right) edge, 66 green 0603 LEDs forming a 5 x 7 dot-matrix
// bitmap of each letter. Built as an Adom molecule so it fixtures into
// the standard workcell via 4 corner machine pins.
//
// Every part is an Adom Basic Part (wiki.adom.inc/adom/adom-basic-parts):
