Thanks Andrew. I have already tried the Win 8.1, then Win 7 check without any joy, so I am pretty sure the hardware setup must be OK. I will try the other ideas and let you know how I get on. Windows isn't very helpful as regards telling me why its failing --- it just suggests I try turning my route...

Hi Andrew, I finally got round to trying out one of the modules I bought earlier this year. I got through the 3 blog tutorials OK, but had a problem when I tried to connect to the unit from my Windows 7 laptop when it was configured as a server. The module was displayed in my list of network connect...

Both the shop description and the above post state that the length of a 30 LED strip is 50mm. Are they really this small?

Just took delivery of one of these and it only took a few minutes to get it up and working using the AnalogReadSerial sketch from the Arduino Examples->Basics menu ......... once I realised that when it says: SL...Sleep mode (Active low) it means that its the sleep mode that is active when its low, ...

OK, tried the resetting. Resetting the board manually causes the port description to change from a Pro Micro to a non-functioning Leonardo for a few seconds before returning to being a Pro Micro. I tried this several times at the point of upload and the Arduino IDE just hangs for several seconds bef...

I can assure you that at no point did I try to program either of the boards as a Leonardo. When I plugged the first one in it was immediately identified as a Leonardo in the devices list (as stated in my initial post). I loaded the Sparkfun Pro Micro driver and selected the Pro Micro in the boards l...

After I get the error message it still shows as a Pro Micro in Device Manager and when I check its Properties it says its working correctly. If I repeat the upload everything behaves as previously -- the red LED is on, the amber LED by I/O header 7 flashes, and after a few seconds I get the error me...

I have just taken delivery of 2 Pro Micros from your latest batch and am having problems programming them from Windows. On my Win 7 laptop (Arduino 1.0.5) I have downloaded the support files from Sparkfun as described above and installed the Pro Micro driver. When I initially plugged in the board, W...

Are you likely to be offering a 3.3V version?
