The motors that move MyzharBot are really powerful, really too much powerful for the motor drivers mounted on the little uBridge shield used originally by the amazing uNav Motor Control board made by Officine Robotiche.
For this reason Mauro Soligo (under a “very little” pressure) realized the new uNavSB carrier board that uses the ST L6205 Dual H-Bridge Motor driver, plenty of power for MyzharBot now!
Furthermore the new board integrates an FTDI module to convert the TTL USART signals to USB and a secure switching converter to power up the uNav through the same motor power source.
