Photos of the newest BLE Nano!

Dear friends,

Here comes the exciting Free Trial, as always! For this month's trial, expect something SPECIAL.

Couple of days ago I was able to grab a handful of our "new-in-development"s right from the production, and a Nano-sized black board caught my eye. It seems to have an extra chip on board, which is strange, a switch between AT / Norm , and an SMD antenna. With my pocket glass, I was able to confirm the etchings on these chips: Arduino 328P and TI CC2540.

Judging from the observations, it is basically clear now this is a "Nano version" of the previous Bluno board, but much smaller. This is an Arduino board that supports Bluetooth 4.0 (BLE) and in a size as small as little fingers. So I decided to hand them out to you guys who are ready to get Bluetooth 4.0 into your project, and make a difference! I have prepared FIVE boards for those who are lucky enough. To participate, just leave the message in comment or drop us an email. PLEASE NOTE this ends in TEN days, so make sure you don’t miss this opportunity!

How to Make a VALID Application

a. You should provide us with a brief description of your test project, and the time you intend to spend completing the test report. 

b. Please also include your email address, DFRobot account, age and occupation(if applicable). A personal blog would be even nicer. Applications that fulfilled BOTH a&b will be considered valid. Leave these info as comment below or email to [email protected] The free trial will end at 5th April 2014. Good luck!
