Zest_Actuator_DC-Stepper

Overview

The Zest_Actuator_DC-Stepper is an electronics development board for 6TRON opensource platform based on Toshiba TC78H651FNG motor driver.

The TC78H651FNG is a dual H-bridge driver for one or two DC brushed motors, which incorporates low ON resistance output transistors.

The TC78H651FNG Forward/Reverse/Stop mode can be selected according to the state of its input control signals routed to the PWM and GPIO pins of the 6TRON bus header. It has a wide operating voltage range of 1.8V to 7.5V with an output current capacity of 1.6A maximum. Besides, it also features built-in protection against under-voltage, overcurrent, and overtemperature conditions.

The Zest_Actuator_DC-Stepper board can be used by 6TRON users alike to rapidly prototype motor driving applications
