I paid about 130 from a reseller (direct price was higher).
The tracing capability is nothing impressive, a bit helpful for low power devices. One day i'll get a "real" Tek curve tracer to match power transistors and fets. For now I buy them already matched whenever i can

I was thinking of making the biasing more complex! I would think something like 100R in series with a 200 ohm trimpot would give decent ranging. Will try it tomorrow.

I still have a few left. Was just surprised by a big rush since I only had a hundred made to begin with.

Hi, Iam trying to make a decision to buy the board. What kind of a power supply is needed? Also what are the dimensions of the board. For some reason the tech diy site doesnt calculate the shipping to UK - shows 0 as the shipping cost.
also, do we need to do any biasing adjustments - if so what exactly needs to be done?

Nevermind, I see it now, not sure why I didn't see it before.

Power supply needs 200mA min. No bias adjust is needed. Thx-RNMarsh
