PMS132B-S08 is $0.05 in quantity at LCSC, CH32V003J4M6 is $0.115
Is the CH32V003 worth twice the price? The PMS132 has a multiply instruction.

What is it about the PMC131-S08A that makes it twice the price of the PMS132B-S08? The datasheet is hard to decipher, I think the PMC has better power noise immunity.

PY32F002AW15U6TR has multiply, $0.104

Hi,
this is not an issue:

I was admiring your flyback driver code and I'd just like to know what the trick you used to divide by a float with only integers here is called:

First: Use an extra IO pin to soldered header.

• WS2812B Emulation
• TX/RX Serial Protocol

Hi,

I saw this pop up on my YT feed - very interesting and love the concept of an addressable PWM driver for nixie tubes.

I actually have a small stash (now 14; I had 20 in total, but already built a clock using an off-the-shelf board which requires 6) of IN-17 tubes which are a bit smaller (and IMO way cuter 😉) than the IN-12 you've used.

So, could the design be altered to suit the footprint of the IN-17? And is it electrically compatible?

Would you mind adding a PDF file of the schematic to the repo, please?

Instead of just P.

The new cap is a little wobbily. Switch back to the 1210 cap.
