I used this with an Arduino Uno R4 Wifi. Since that uses the Renesas chip, I used the digitalWrite method (and not the port mapping method that's recommended with the older Atmel chips), and that worked just fine for my use case. I'm not aware of *any* board out there for any maker-friendly system that can drive a bipolar output at that voltage without a fair amount of finicky EE work. Driving the input of this one with two center-tapped 9V batteries in series (as one of their suggested ways) worked and was easy enough. I'm using a single board at this time but looking to get a second one. It's nice that they thought about how to stack multiple power DAC boards on top of each using the chip-select output if you want multiple independent outputs.

Tip: unless you enjoy soldering (I don't), get the variant with the headers already soldered on.

Very useful board, fills a gap with few other options.

For Power DAC Shield

I needed a 0-10V variable power supply capable of driving 100mA and there are very few other options besides expensive and hard to get lab equipment or rolling your own. These boards fit the bill and saved me a lot of time and expense.

I needed a total of 8 outputs, so ended up adding bodge wires for the extra chip select pins on the top 3 boards.

I also hacked one up for single ended operation. This gives me full 12-bits resolution across a 0-12V range. Instructions are here if anyone else needs this...

Sure the code and documentation for this board could be better, but not too hard to figure out.

I just put in an order for my 2nd batch.

Great product.

For MOSFET Switch

I was a bit confused at the operation until they clarified.
You provide the desired voltage to switch on Vcc (e.g., 5 volt, 12 volt, ...) and the ground.
These wires should be sufficient to carry the desired load current.

You provide a switch signal (e.g., 5 volt or 3.3 volt) to the sw signal to close the switch and gnd to open the switch. The LED turns on when switch is closed.

When 5 volt or 3.3 volt are provided, the neg output connection is shorted to ground thereby completing the output circuit.

I wondered what would happen if I applied 110 volt ac. I found that a 150 watt bulb dimmed. No damage though so this product is robust.
