NEW!!! TNC-Pi A Specialized Version of TNC-X For the Raspberry Pi TNC-Pi is a special version of TNC-X designed to interface directly with the Raspberry Pi computer. It can connect to the Pi either via the Pi's serial port, or via the I2C protocol. In the latter case, a single Pi can support multiple TNC-Pi's at the same time, since each TNC-Pi can be given a unique I2C address. |

NEW!!! TNC-Black A Specialized Version of TNC-X For the Beaglebone BlackLike the TNC-Pi, the TNC-Black is a specialized version of TNC-X. It is designed to stack on top of the Beaglebone Black. Like the Raspberry Pi, the Beaglebone Black is an inexpensive single board computer. But the BBB has a beefer processor with better graphics and MUCH more I/O. |

TNC-X is available in two versions: with and without a USB port. Both versions contain a standard serial port, but the USB version also allows the TNC to be connected to a computer via it's USB port as well. Drivers that are shipped with the module make it appear to the host PC as a standard serial port. Thus PC software that expects to see a serial port on the computer will interpret the TNC-X as being connected to such a port, even when the PC has no serial ports, or they are all used by other applications. In addition, when the USB option is used, the TNC can be powered from the USB port of the computer; no other power supply is needed. Even without daughter
boards (or the USB option) the device works as a fully functional stand
alone KISS mode TNC. The idea behind the expansion options was to provide
a platform that would allow additional functionality to be added to the
unit with the investment of very little design time and very few parts.
A complete technical description of TNC-X is provided in a paper that was presented at the 2003 ARRL/TAPR Digital Communications Conference in late September in Hartford Connecticut. A copy of this paper can be accessed here. Please note that there have been a few design changes since the publication of this paper. At some point I will revise the paper, but I've not as yet had an opportunity to do so. Any questions concerning TNC-X can be directed to the developer, John Hansen, W2FS. Here are some common configurations you can order with one button press: |
