The board sold as PROC V1.1 is not the board in this repository.
Visible on the vendor's render (mirrored at
doc/img/proc_v1.1.png) but absent from control2.*:
- a PWM pad — the firmware's
#define PWM 5 puts it on Arduino D5
(PD5, package pin 9), which is unconnected in our rev-1.0 schematic
- a W5500 SPI breakout header (
MOSI CLK CS MISO INT RESET)
- separate TTL-level serial pads next to the RS-232 ones
- per the vendor hardware manual, V1.1 "no longer distinguishes switch
polarity", implying a different optocoupler output arrangement than the
EL357N single-transistor output used here
No V1.1 schematic, layout, BOM or Gerbers are published anywhere.
Impact: if OSL's units are V1.1 — worth confirming by looking at one — then
this repository documents the wrong revision, and any repair, respin or
modification starts from an incomplete picture.
Options: ask the author whether V1.1 sources can be published; or trace the
deltas from the render and photographs and maintain a V1.1 branch ourselves.
Asking is much cheaper and he has been responsive.
