Description

Bluno Beetle - The smallest Arduino Board is another milestone in wearable electronics device area based arduino uno, which makes DIY users have more options in the project design. It is fully compatible with Bluno in instructions and procedures, supporting Bluetooth HID and ibeacon modes. 

And it not only supports USB programming, but also wireless programming method. With the V shaped gilded I/O interface, it is convenient to screw conductor wire on it, which could a good choice in the wearable market.

Small footprint, just enough pins (can use conductive thread), highly recommended for wearables.

Very expensive, 2016 model, unsupported small development module. Connecting to the Bluetooth from a smartphone is a nightmare. Common Bluetooth password "0000" and "1234" doesn't work. Spent too much time on Google on different forums to come across with with six "0"s but nothing documented on DFRobot. DFRobot FW last updated 4years ago and MIT App Inventor doesn't support this BLE 4.0 device. Doesn't connect with MIT App Inventor with just "BluetoothClient1.Connect Address" and will return error "507". You need to manually configure the Bluetooth through AT commands just to establish communication but still no luck unlike HC-06 Bluetooth on Arduino UNO which works fine without configuring AT commands and setting UUIDs. This one, you can spend the whole week searching through forum to find how to configure Service UUID and Character UUID just to establish communication. It's nice to hava a smaller foothprint but sorry, it's a waste of money, time for mass project. Really, I can't recommend.
