http://www.twistedpearau...cid_hd_bp_1.0_manual.pdfsays: remove R7 for 3.85v output If you need exactly 3.3v, use a LDO regulator... might need a small amount more headroom than 3.85 so change R7 as needed. I can't remember what the minimum headroom should be but I would use 1V at least. Edited by user Tuesday, September 29, 2015 2:26:24 AM(UTC)

Yes. Replace one of the LEDs with a diode (1N914 or the like) and you are good to go.
