The first boards came back with the new power supply based on the TLV61225. I haven't extensively tested the current draw, but the voltage, noise and ripple seem perfectly acceptable. The first boards I ordered had a couple errors on them, so I'm ordering a follow-on batch to correct them.

I am continuing to design standalone boards, but I'm unlikely to order another manufactured batch of them, as demand is quite low compared to the complete movements, and I have a ton of them still in stock.
