A Terminal Node Controller (TNC) is a device used in packet radio. The TNC is analogous to a MODEM in wired communications. The TNC converts analog audio signals that have been received over the radio into digital bytes to be sent to a computer, and also converts digital bytes from the computer into analog audio signals that can be transmitted over radio.
Costal ChipWorks sells a TNC kit that is designed to connects to a Raspberry Pi computer, in 1200 baud and 9600 baud version, the TNCPi9k6. There is also a specific version of the TNC-Pi compatible with the Terrestrial Amateur Radio Packet Network (TARPN)
Direwolf is a TNC implemented as open-source software, rather than hardware.
