= Introduction =

If you have sufficient soldering skills it is possible to build a cheaper BlueTooth ICS adapter by using the RN-42 adapter and a small number of parts.  The RN-42 Bluetooth module requires 3.3 volts for operation and communication so we will need some circuitry to adjust voltages.

Below is a schematic of how the RN-42 module could be used to build a ICS adapter.
