From the project

Motorized solder paste dispenser

+ Controled with 32bit processor STM32F103C8T6 ( original is STM32F030) + used output H-bridge for motor control TB67H451FNG. No need cooling with during operation. + + DC micromotor 6V / 60 rpm with gearbox without thread rod

+ redesigned mechanism of operation and piston mounting and mainly redesigned Syringe mount, which can be removed and put on without disassembling the dispenser
