BTS7960 Motor Driver Module 43A H-Bridge High-Power
- Double BTS7960 large current (43 A) H bridge driver
- 5V isolate with MCU, and effectively protect MCU
- 5V power indicator on board
- voltage indication of motor driver output end
- can solder heat sink
- Overvoltage lock up
- Undervoltage shut-down
- Overtemperature protection
- Current limitation
- Short-circuit protection
- Just need four lines from MCU to driver module (GND. 5V. PWM1. PWM2)
- isolation chip 5 V power supply (can share with MCU 5 V)
- 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), can also use the on-board 5V supply
- the supply voltage 5.5V to 27V
ULN2003 Current Relay Driver IC
- Contains 7 high-voltage and high current Darlington pairs
- Each pair is rated for 50V and 500mA
- Input pins can be triggered by +5V
- All seven Output pins can be connected to gather to drive loads up to (7×500mA) ~3.5A.
- Can be directly controlled by logic devices like Digital Gates, Arduino, PIC etc
