Thinking About Building Again - 1st Sub-Ohm Design

[AlleyKat]

looking for advice on best reasonably priced boards to use, etc. My last adventures in build-ny-own modding was back in the days of high voltage/high ohm vaping (dual batteries up to 7.4V - variable, of course...& 2.5-3.0 ohm coils).

I also need to find a new board for my old ohm meter, it can't read anything below 1.0 ohm - errors out (or advice on where to pick up a not too expensive but very accurate meter for sub-ohm coil & mod builds).

No such animal.

The $10 box ohm readers are not that accurate for sub-ohm, especially to the hundreth of an ohm. I even question if they can be accurate to a tenth of an ohm. Leave a generous margin of safety using these.

A Fluke digital multimeter may be accurate enough but they cost hundreds of $$ and require routine recalibration to maintain their precise accuracy.

Concerning a board chipset, I'd suggest a DNA board by Evolv.

Thanks for the advice! I was thinking more along the lines of GeekVape & similar meters for sub ohm builds - but DIY (more for the experience than cost, although money is tight). Would definitely want to have hundreth accuracy (0.15, etc) but don't see the need for thousandths of ohm accuracy yet....though who knows, that day may come.
DNA boards are great from what I've seeen,heard & read about them but are also on the high end cost-wise. Any mid-range cost alternatives you can suggest to start out with?

None that I am aware of. You might inquire here: Modding Forum
