The Bluetooth module wants 3.3v logic levels so that is taken into account. The image above shows a buffer chip doing the conversion, but the Fritzing schematic on the post uses a voltage divider.

I use my Nokia N810 internet tablet for the same purpose. On my harley, there is a J1850 stream, so I just link that into an obdpros OBD2-to-bluetooth module (which has an autostart mode) and I ...

You know, we don't see too many didgeridoos in these parts (and for good reason, seeing as how it is little more than a pipe) but wait'll to you get a load of this aerophone-wielding maniac: Kyle ...

The Arduino, Bluetooth module (check your specs, some HC-05, and HC-06 may come on a breakout board expecting 5V), and USB Host shield all run off of 3.3V, but devices you want to plug into the ...

DastardlyLabs uses a USB host shield, a Bluetooth module, an Arduino Pro Mini, and a bunch of other random parts to create this little device.

Arduino is the first widespread Open-Source hardware project and, since 2005, has become almost ubiquitous in microcontroller projects. The Arduino Pro line is aimed at the more professional user who ...

U-blox has announced a module combining Bluetooth Low Energy 5.2 and dual Arm Cortex-M33 cores – M33 is Arm’s security-enabled small embedded core. Called Nora-B1, at 10.4 x 14.3 x 1.8mm the modules ...

Arduino 101* module; Grove* – Starter Kit Plus; A standard, A-plug-to-B-plug USB cable; ... The Arduino 101* Bluetooth® LE is based on the Generic Attribute Profile (GATT) architecture.

Arduino has not included active power consumption on its data sheet but, according to the uBlox datasheet, module consumption is 286mA (Wi-Fi Tx 802.11n HT20 16.5dBm 100% duty-cycle) or 220mA ...
