If you do solder the pins directly, make sure you keep the wires separated with a bit of tape so nothing shorts unintentionally. If you want to make your life easier, you could get a breakout board instead of actually soldering wires to the pins. We'll need to access the SPI, VDD, and GND pins. Here is the RN-42 module which we'll need to extract the firmware from. And here are the voltage dividers I made from salvaged resistors. We'll cut up a few pieces and solder them to some loose wires so that we can connect it to our breadboard. Here's the parallel cable I'll be using, the male end will connect to the PC and the female end will connect to the chip. We'll also need an external 3.3v power source to power the chip. We'll simply add an 100ohm resistor here to prevent the the module from being overloaded. The MISO pin will transmit to the parallel port at 3.3v, which the PC will still recognize. We'll need use a few resistors to create voltage dividers, and that will step down the parallel port's 5v levels to the chip's 3.3v levels. For the chip to communicate with our PC, we'll need to connect the SPI pins into these parallel port pins. The link to his blog is also in the description box below.

I'd also like to give a shoutout to Robin Gross who was one of the first people to document how to build a programmer for this chip. So head over to the link in the description box below to download their BlueSuite toolset, which is what we'll be using to dump the module's firmware using the parallel port of a PC. The chip manufacturer, CSR, has made their tools publicly available. So here's the plan - to make our $3 module HID enabled, we'll just have to copy over the firmware from the RN-42 chip to the HC-05. The only differences between these modules are the firmware and the location of the pin outs. But luckily, this module actually uses the same chip as the RN-42 bluetooth module, which also powers the $40 BlueSMiRF HID modules. By itself, this module isn't HID capable. This cheaper module is the HC-05 and sells for around $3 on ebay.

This bluetooth module, however, is 3 bucks, and so we're going to turn it into a bluetooth HID module. But the cost of both of these modules are more than what I'd like to spend for my entire project. There's the BlueSMiRF HID, or the Bluefruit EZ-Key HID. What if we want to build our own HID device? What would that cost? Well, to begin, we're going to need a bluetooth HID module.

What's great about them is that mobile devices nowadays support them out-of-the-box, so there's no need to install any app or make a custom app just to get it to work. HID Devices are input devices like bluetooth mice, bluetooth gamepads, bluetooth keyboards, etc. Hey! This video is about Bluetooth Human Interface Devices.
