BTN7971B motor driver module

Overview

This module uses four btn7971b high-power driver chips to form an h-bridge, the maximum current can reach 70a; the auxiliary power supply uses ams1117-3.3v voltage regulator tube, with an accuracy of %3, and can make the system operate more stably, using 74lv245 three The steady-state bus transceiver is used to process 4-channel pwm signals. In terms of interface, a gnd in** represents the input pwm out, which represents two-channel current collection signals, which can collect motor current.
