esp8266-d1-mini-maxxfan-b
Wireless Module for MaxxFan (G6L-1P relays)
This module uses G6L-1P relays - and its design is inspired by Everlanders Automation projects (video) (Project Home page), where a Wemos D1 mini wireless remote control option is added to the MaxxFan in the Everlander rig.
In the Everlander project G6L-1P relays are used, so this PCB also uses G6L-1P relays.
- Here is a similar PCB design, but it uses G6K-2P relays
- Here is a general PCB design, that can hold up to 8 mini relays
Project Status: PCB design verify (rev.A1 - 2023 May 16)
Here are some screen shots:
- TOP side
- Bottom Side
Notes about un-knowns:
- I do not know if the numbering (1-8) is similar to the actual MaxxFan. This needs verification.
Use the PCB viewer if you would like to see/test the entire copper path as it switches sides and/or connects to several solder points.
