BTS7960 Motor Driver - 43A High Power Double DC Stepper Driver, H-Bridge, PWM, for Arduino

My project was delayed by several weeks due to me not noticing that my motor driver is faulty where the PWM pin controller was fried and faulty, this caused a lot of hassle and time wasted and I am not happy

DAOKAI BTS7960 Motor Driver Module 43A High Power Double DC Stepper Motor Driver Module This is a module for the hobbyist who wants to control it from an Arduino, Raspberry Pi etc. and can be used for a variety of things. The module comes with a ribbon connector to fit the socket, a heatsink, and two screws to fit the heatsink to the PCB. Be careful you don't lose the screws. I'd suggest that you fix the heatsink straight away, or put the screws in the heatsink holes until you're ready to use it. Rather than the heatsink fitting '/ sitting directly onto the component, for what is normally the best heat transfer, the heatsink fits onto the underside of the PCB and the heat is transmitted from the component, through the PCB, then to the heatsink. I don't know how effective this is if there is a lot of heat being given off. The connection point details are marked on the PCB. There is no information provided with the driver module, such as how to fit the heatsink (easy to do), specifications etc. Information is provided on the listing page, but make a note of it in case the page disappears. The module appears to be good quality, with no obvious solder flaws. There is a screw hole at each corner for mounting. It is best to use this module mounted on spaces, even temporarily, to avoid shorting out any of the contacts on the underside of the board.

This is a reasonable motor control module. It’s easy to use as there’s enough information in the listing to get you going. Heatsink placement feels a bit odd; I’d have thought it would be better to be stuck directly on the chips.

They work well with no problems .

Hブリッジ回路のモータードライバー。 PWM信号で速度調整可能な正転、逆転の他、ブレーキとフリーにも対応。 ESP32に接続して使っています。 自分で部品を集めて作るのに比べて、コストも時間も短縮できて良いです。

ne ho già un altro e devo dire che sono ottimi per gestire motori e motoriduttori

Excellent product. Can be used to control sizable DC motors and if a heat sink is properly mounted, it runs cool. Writing code for the device is easy enough and if requires, ready to use Arduino libraries are also widely available. One thing it isn’t is a stepper motor driver so keep that in mind.

This can be used for far more than driving motors, it is a high current (43A) high side or low side driver. This can be used with only a connection to power and the enable pin. All pins are pulled down with a 10K resistor. With PWM set low, this becomes a simple floating on/off switch like an open collector transistor, but with a lot of power. Low side driving has the lowest on resistance of 7 milliohms, high side has 9 because it is P MOS. This is a very convenient way to drive heavy loads. I just supplied 5V to the Vcc pin with a 2K resistor and 5V zener. I loke to solder in zeners to back of board to ensure the chip supply never goes over 5V. This comes in two pieces with some screws. There are vias which will touch the anodized heatsink. I don't trust that for insulation and used thin KAPTON tape on the heatsink. In addition, some heatsink compound was added to the board over the heat conducting vias. This driver can be used up to 45V. The capacitor on the board is rated 50V. What a nice simple dual load driver that comes with a heatsink. It comes with eight dupont MF cables. Only one is really needed for driving each chip.

壊れていることがわからず、何度かテストして作動ができませんでした。自分の設定が悪いと疑いつつ新しいものを新たに買ってテストしたところ使用ができ自分の使い方が正常であることがわかりました。返品したいと思っています。手こずった時間を返してほしいものです。
