Schematics differences with v1? #55

First, thanks for your project and sharing the instructions with it! 👍

I successfully made a simpler version based on your v1 schematics, using a nodemcu 1.0 board (with 3.3V everywhere) and a single dmx output. It works very well 😄

I looked into the v2 schematics, and saw that you added a bunch of resistors, could your explain why? If I only use it for DMX output, not pixels/RGB is it useful to move to the new design?

Thanks!

The resistors are for DMX termination and are recommended for RDM. I based my design on an Arduino shield design by Mat Hertel - he explains it here: http://www.mathertel.de/Arduino/DMXShield.aspx They are not needed for pixels at all and things will probably work fine for DMX without them

Thanks for the info!
