The RB_STM32_DVM_MTR2k is a version of our popular STM32_DVM modem that is custom designed to work with the Motorola MTR2000 repeater. Includes in addition to the features of the "standard" STM32_DVM, it adds additional GPIO, wildcard "faker", and additional serial port I/O communications. This version also includes a NanoPi single-board computer. There is no need for a separate platform running MMDVMHost. The STM32_DVM_Mtr2k is a complete ready-to run solution that simply plugs into the middle card slot of your MTR2000 repeater.
