Can DAPLink be used with nano1?

It seems to get unusually hot, may be something to do with the VIN pin supplying 5V from USB? The old MK20 board had a VDD pin in its place.

I was just using the Proto Board when I realised there is no indication as to how the BLE Nano 2 should be inserted. A nice improvement would be to have the pin numbers written on the Proto Board (in between the female pins), or at least to have the VDD pin indicated to give a sense of direction.

I tried a quick test using some existing code.

I have an existing application that uses a Central and Peripheral set up (Central is the new Nano 2, Peripheral is a Nano 1.5). They communicate using the Nordic UART mechanism using a custom communication protocol. The Central Nano 2 has an Adafruit 128x32 I2C display attached so some messages can be displayed. Thus I need the Adafruit GFX and the Wire libraries as part of my build.

Recompiled unmodified code on the Central, which works well on a Nano 1.5. Compiled fine and operated correctly. The Nano 2.0 finishes initialization noticeably quicker than a Nano 1.5 running the same code. Operationally I cannot tell any time differences as my application is timer based. Across the BT connection...all seems to be working fine, each connected, and are passing data between each other.

I was alarmed at the start as it seems the Warning Level is set by default higher than I'm used to seeing. Its not a problem however, I should deal with unused, uninitialized, etc variables.

I use the Arduino, 1.8.1 environment.

I thought I'd provide a little feedback. Thanks for the great BLE module!

After some experimenting I'd like to create a PCB on which a MB-N2 will be mounted. To do this I'd like to use Fritzing (as I assume others will too). At the moment there only is an EAGLE part available, but it would be very convenient if there was a Fritzing part as well for this particular use-case.
