We love pulling out our 5 Megapixel USB microscope for inspecting PCBs once in a while

New AutoTune algorithms intelligently back the minimum range right up to the transducer ringdown for the very best performance possible

DFRobot Bluno (Bluetooth 4.0) _MAKE_ROBO_KITS Inside of the chassis areIt's time to get Bluetooth 4. 0 into your Arduino project and sync it up with your phone! For aficionados of smart devices and wearables with this new tech (Bluetooth 4. 0 low energy, BLE), now you can go further than hacking things apart to start prototyping with your board. As a member of the Bluno Family, Bluno is the first of its kind in integrating a Bluetooth 4. 0 (BLE) module into "Arduino Uno", making it an ideal prototyping platform for both
