This is the same Roving Networks Bluetooth module that you already know and love, but it comes firmware-configured for the HID protocol. HID, or “Human Interface Device,” is the communication protocol used for computer peripherals such as keyboards, mice and joysticks. This makes the RN-42-HID a simple and powerful tool for creating wireless peripheral devices which can be universally recognized and used without the installation of special drivers. The manual included in the documentation below goes into more detail about the Bluetooth HID profile.
The RN-42 is perfect for short range, battery powered applications. The RN-42 uses only 26uA in sleep mode while still being discoverable and connectable. Multiple user configurable power modes allow the user to dial in the lowest power profile for a given application.The RN-42 is even FCC and Bluetooth SIG certified making it a complete embedded Bluetooth solution.
This skill defines how difficult the soldering is on a particular product. It might be a couple simple solder joints, or require special reflow tools.
Skill Level: Competent - You will encounter surface mount components and basic SMD soldering techniques are required.

If it requires power, you need to know how much, what all the pins do, and how to hook it up. You may need to reference datasheets, schematics, and know the ins and outs of electronics.
Skill Level: Competent - You will be required to reference a datasheet or schematic to know how to use a component. Your knowledge of a datasheet will only require basic features like power requirements, pinouts, or communications type. Also, you may need a power supply that?s greater than 12V or more than 1A worth of current.
