I really like the PCB but i had issues getting all the parts. From germany without an creditcard it is really difficult to get all the parts from digikey. An additional parts kit or an fully assembled option would be really nice.

Hi Alexander,

Thanks very much for a review.

Yes, the parts have been more challenging to get for some people than I had originally thought.

Once the next revision is complete I'm hoping to sell them as a full kit or assembled unit.

Thanks again and I hope you enjoy your product!

Great product

For PCB For Arduino Programmable Constant Current Load

I purchased two of these boards as my first, real surface mount project. The boards are great and the tutorial on Instructables was terrific. The only recommendation that I would have would be to better indicate on the silk screen the polarity of the SMD diodes, LEDs, and the orientation of the ATMEGA chip. By using the schematic, some references on-line, and the data sheet for the ATMEGA chip, I think that I got it all right. Will find out tonight when I try to install the firmware.

Thanks very much for a great review.

Yes, you are correct, the markings can be a little hard to make out!

The cathodes of the leds and diodes have little 45 degree corners and the chip has a 45 degree slop in one corner to match the one on the atmel.

I will certainly improve those on the next boards.

Thanks again!
