Let's fuck hard with some fans using an [[Arduino|Arduino MEGA]] and a [https://heltec.org/project/wifi-lora-32/ Heltec LoRa ESP32 v2]. These will be used with my [[MO-RA3]] to collect realtime data (fan RPMs, temperatures, etc.) and provide realtime control (fan PWM/RPM, RGB signals). We will also need a TXS0108E level shifter, a LM2596 buck converter, and three IRLB8721 logic level MOSFETs.

We use a 12V PWM+DRGB hub for the many fans of the MO-RA3. Only one fan's RPM will be reported (whichever one is plugged into the red fan hookup), so it's important that we use the same model throughout. The hub has a two-wire hookup for tach and PWM (12V and ground are provided through the SATA power hookup). Looking at the hub with the clear side oriented up, the left wire is the PWM input, and the right wire is the tach output.
