Current/Voltage Tester board with DP5031

Hi,

For those interested in a cheap funny board to test USB current consumption/voltage or even check USB D+/D- and ID signal
I have designed a new PCB board Current Voltage Tester v1.0 Rev1 (Size 50mm x 31mm).
Current or Voltage can be measured using standard Banana Plug Connector (for voltmeter) or a standard header.
The PCB include also easy access with Oscilloscope to D+, D- and USBID pin for checks.

See photo of the board hereafter:

A very cheap case is also planned depending on feedback about that board.

Nota: For those interested I plan to buy 10 PCBs and I could sell some bare PCB for very good price (like 10 Euros including shipping for Europe for 2 PCB).
If lot of people are interested by more PCB I could lower the price and buy a batch of 20 or 50 PCB and sell them for even less (like 20 euros for 5 PCB including shipping), for information all PCB will be 100% E-test.
Contact me in the forum or by email titanmk@gmail.com

Best Regards
Benjamin

Cool product. 

But I'm not too sure that 10 EUR for two boards is such a very good deal.  10 EUR = 13 USD and that gives you 10 boards inclusive shipping from Seeed.

10 EUR for one board inclusive all parts would be a decent deal though...

Hi Matseng,

Of course it is maybe not the best deal but shipping is just too expensive and for shipping without tracking (just express) it can be even lower price or why not a DIY package including the components.
But anyway it is just an offer and I do not really win any money on that considering the time spent to package PCB and send them in low quantity.

Nice PCB 3dview, but isn't it missing a current sense resistor or pcb trace loop for current measurement?

No there's no any sense resistor as it is a tool to be used with a multimeter.
In fact you just need to plug multimeter in current/amp mode in measure current pins.
The best is to connect a uCurrent with burden voltage take into account to measure accurately device with very low power consumption.

I am really interested in getting a few of these. I have everything except the USB A port.
