I'll write it up later tonight or tomorrow but short version: find the URL I linked to the schematic/board files in my first post, pull it up, then there's a menu option for ordering PCBs from JLCPCB. It's pretty much just selecting that you want assembly as well after that, the board layout has...

Very good point. It'll be interesting to see what scoping the UIS connectors reveals about the new protocol - I presume it's not just simple PWM anymore since the UIS multiplexers are a thing.

Speaking of... The boards have arrived! I'll post pictures later when I'm off work. They seem to work fine with two fans hooked up, no sign of the instability @shimbob was seeing, but I want to let them run for a few days before saying that with any certainty. But yeah. They work perfectly...

Oh that's fascinating. Especially if it's just something off the shelf ish like I2C it'd be easy to interface to. Ugh, I'm so tempted to drop my scope on my 6" Cloudline now and see, even though I've already solved my own problem with the Molex boards...

Hahaha I mean... I could be convinced! I'm actually using my fans for something that has nothing to do with growing (venting laser cutters and 3D printers) so I've never had a need for the driver side of things. What sort of interface is that? Like are they just a bunch of N volt 2-wire...

Oh interesting, I'll have to keep my eye out for problems. The one-fan prototype has been working fine so far but who knows once multiple fans are involved... What sort of stability issues did you run into? Re barrel plug - yeah that'd be a breeze to add to V3. In the mean time, powering the...

Joining the first post club! So I've been messing around with making a custom ESP32 circuit board to control my two Cloudline fans, the goal being to design a board that: just works - plug it in via USB, program it, then hook it up to your fan, no additional steps required (because I'm lazy) I...
