			* I ought power the Heltec through the 5V pin rather than the USB. In this case, it moves to the LM2596, and the only thing drawing 5V is the CODI6 (for ARGB LEDs).
			* I think I can eliminate the MEGA2560 entirely? We only need move the three tachometer inputs and three RGB outputs at this point. Eliminating it would also (probably) eliminate the level shifter.

	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.		We use a 12V PWM+DRGB hub for the many fans of the MO-RA3.

Sending from the 5V MEGA directly to the Heltec will damage the latter. We instead go through a ~~TXS0108E level shifter. The 5V line is taken to VB, while the 3.3V line is taken to VA. TX2 (~~pin 16~~) on the MEGA is taken to B7 on the level shifter. A7 goes~~ to pin 36 ~~on the Heltec, which is configured as RX2~~.
