SparkFun Support and Front Desk will be closed on Thursday 11/14 from 1-2:30pm for a company event. Please plan to pick up your orders before or after this timeframe.
The BlueSMiRF HID is essentially the same board as the BlueSMiRF Silver but the populated RN-42 comes loaded with the HID firmware. 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 remote unit can be powered from 3.3V up to 6V for easy battery attachment. All signal pins on the remote unit are 3V-6V tolerant. No level shifting is required. Do not attach this device directly to a serial port. You will need an RS232 to TTL converter circuit if you need to attach this to a computer.
Note: This is a single unit only. We recommend the purchase a USB dongle to interface to a computer if you do not already have access to a computer with Bluetooth connectivity.
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: Noob - Some basic soldering is required, but it is limited to a just a few pins, basic through-hole soldering, and couple (if any) polarized components. A basic soldering iron is all you should need.

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: Noob - You don't need to reference a datasheet, but you will need to know basic power requirements.

This bluetooth modem is great! I was able to connect it to my Arduino project without any trouble at all!
