The Nucleo TNC is a breadboard implementation of the Mobilinkd TNC3 using a STM32L432KC Nucleo32 board. This TNC faithfully implements the audio section and EEPROM storage of the TNC3. It omits the battery charging and Bluetooth components of the TNC3.

Source code for breadboard TNC based on STM32L432KC Nucleo32 dev board

Important Note

If you regenerate the STM32 code, please note that the LL ADC driver in the 1.12.0 version of the HAL driver is buggy.
