ITEM NAME:Semiconductor Motor Driver Auto BTS7960 43A H-Bridge PWM Drive For Arduino W3Y4 Semiconductor Motor Driver Auto BTS7960 43A H-Bridge PWM Drive For Arduino W3Y4 This driver uses Infineon chips BTS7960 composed of high-power drive full H-bridge driver module with thermal over-current protection. Double BTS7960 H-bridge driver circuit, with a strong drive and braking, effectively isolating the minicontroller and motor driver! High-current 43A Specification: Double BTS7960 large current (43 A) H bridge driver; 5V isolated with MCU, and effectively protect MCU; 5V power indicator on board; voltage indication of motor driver output end; can solder heat sink; Just need four lines from the MCU to driver module (GND. 5V. PWM1. PWM2); isolation chip 5 V power supply (can share with MCU 5 V); Size: 5.5 x 5 x 4 cm (L x W x H) Weight: 67g material: metal Able to reverse the motor forward, two PWM input frequency up to 25kHZ; two heat flow passing through an error signal output; isolated chip 5V power supply (can be shared with the MCU 5V), Also can use the on-board 5V supply; the supply voltage 5.5V to 27V Package included: 1 x Semiconductor Motor Driver Note:Light shooting and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3 cm.
