// "STEVEN" desk nameplate molecule, 5 x 7 dot-matrix edition.
// USB-C powered from the EAST (right) edge, one white 0603 LED per lit pixel,
// each with its own 470 ohm resistor (~4.3 mA, keeps the whole board under the 500 mA a USB-C source gives without negotiation). Four corner machine pins fixture it into
// the Adom workcell.
//
// Every part is an Adom Basic Part (wiki.adom.inc/adom/adom-basic-parts):
//   LED    IN-S63BT5UW        white 0603, Inolux
//   R      CR0402-FX-4700GLF  470 ohm 1% 0402, Bourns
//   R_CC   CR0402-FX-4701GLF  4.7 kohm 1% 0402, Bourns  (USB-C Rd)
//   C_BULK CL21A106KOQNNNG    10 uF X5R 0805, Samsung
//   C_HF   0402B104J160CT     100 nF X7R 0402, Walsin
