Great adapter board for reading current

For Oscilloscope Current Probe Adapter

It's not as robust as I would like (I would like to read 3.3v up to 500ma) but it is near perfect for hobby-users. I use it for checking low-power gizmos that I run on batteries where run time is critical -- squeezing every little ma out key, and this makes it easy to visually see what changes result in what...
I didn't have any bnc cables around, so I had to solder on a (standard) header pin (not included) so I could attach my scope probes. The board is well labeled & built. The only thing I would suggest is read the description carefully and understand the limits. Works great for what it is intended for!

---- Edit 26 April 2016
Having used it for a while now, I love it even more. I ended up putting it in a small box as it could get odd readings if I touched it; or it grounded to something else. (duct tape worked great until I happened upon a perfect box). I recently built a few "uCurrent" boards & compared it this; readings were very close. In fact, this fluctuated (accurately) more than the uCurrent; this is good when viewing on an oscilloscope as you get a better feel for leds flashing, or more loss -- the uCurrent seems to buffer the flutters.
You really can't go wrong for this price!

Low-power battery projects are indeed what I built it for - glad you found it useful there :)

The space reserved for the 3pin header is useful for attaching non-BNC connectors, indeed. I decided not to populate it because people might prefer header or socket on there, so this gives them the choice - the intended users for this kind of equipment should be able to easily handle fitting that themselves.

As to the current-reading limit of 100mA per volt of supply, you have found that you can't read up to 500mA when supplied at only 3.3V. It was a trade-off in design, between requiring a separate external power supply, or tapping off the same supply that powers the load. I opted for the latter as it makes for an easier setup, and should still be within the limits of what most designs require. If I did a redesign for a newer version, perhaps that's something I could look into - maybe a 3pin header you can switch with a jumper, to either tap off the supply as it does now, or use a separate supply input for the current amp. In such a setup you'd be able to supply 5V there to give it the 500mA measurement ability, but still supply 3.3V to your load.

Perfect for those 14 pin SOIC ATTiny's

For ATtiny 14pin SOIC-to-PDIP adapter

I recently got a batch of tiny SMD ATTiny24A's and needed a way to prototype easily with them.... and this is it. It plugs in a standard breadboard, has a 6pin ICSP header and a zero-insertion-force socket to hold the chip in place. I am new to programming adapters, so it took me a couple of tries to place the chip and the cable in the right direction, but now that i got it right, it's all good.

Predictably, when you are facing the "ATtiny SOIC-to-PDIP14" silkscreen markings, you want your pin 1 (marked by the little hole) at the top left.

Leonerd was very helpful and friendly too, so that's cool too.

Thanks! Review Image
