These modems work as a serial (RX/TX) pipe. Any serial stream from 2400 to 115200bps can be passed seamlessly from your computer to your target. They have been tested successfully over open air at 350ft (106m)! The latest version of this board also breaks out PIO4.
Note: 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 of a USB dongle to interface to a computer, if you do not already have access to a computer with Bluetooth connectivity.
This board ships without headers,
