H7 pinout for Rev 3. Upgrading to Rev 4 and new Relay PCB

Post by Jrlee »

It appears to me that the schematic for the Rev 3 PCB is in error relative to relay pinouts at H7 header. Rev 3 shows the COM connections at bottom of the callout for OUT1 and OUT2 respectively. BUT IF you look at a photo from July of 2019 (my machine) it clearly shows the wires at H7 header NOT connected to the lower pin for the respective relays 1 and2. The open connections should be (acording to rev 3 schematic) for the common relay terminal. What is the correct pinout at H7? I appreciate the hellp
