Good product but the image with the rulers to show the dimensions is incorrect. Its 18mm by 45mm not the ~27mm by ~64mm as the picture shows.

I'm a little confused about the specification. For SPI it states that the hardware supports it but the DFRduino language does not. If I use the Arduino
IDE will I be able to use a SPI wireless module like the nRF24L01 with the v4.0 of this? Thank you!

DFRduino Nano product, for the quantity of 25 pcs is there any?

That's all well and good, and I can do that, but I'm concerned that your product was either not described accurately or failed out of the box. I'm considering this for a client and need assurance that things will work as promised.

Addendum to my previous reply:

I also have an Arduino UNO. It connects just fine, so there must be something different about the Nano's firmware.

Thanks for the prompt response. However, your suggestion did not solve my problem. I attempted to run the two files you pointed out; the -x86 would not execute (64-bit OS not supported). The -amd64 ran to completion but I still have no Arduino Com port in Device Manager.

Perhaps more info about my system will help. From Control Panel->System:
Processor: Intel Core i5-5300 CPU @2.3GHz
RAM: 8GB
System Type: 64-bit OS
OS: Win7 Enterprise, SP1

Awaiting your next suggestion...

Thanks!

Hi, the arduino IDE doesnt seen to recognise this? Any ideas

What are the main differences between old versions and the new 3.1 ? Is there any schematic update?
