SUNFOUNDERRobot HAT Expansion Board Designed for Raspberry Pi 4/3B+/3B/Zero W Robot, IoT, Sensors, Motors, Servos Driver, Inclulded Rechargeable Battery, 5V2A, Speaker, ADC, PWM, IIC, UART, SPI

Bought this to upgrade by PiCrawler, primarily to allow recharging the battery without removing them. Worked like a charm. Only thing I had to do, apart from replacing the existing head, was to print a battery holder for the supplied battery pack.

I wanted to venture into robotics so I picked the robot hat what a grate decision!it was a breeze to set up and works flawlessly motors sensors all on on the same boardand so many projects online would really recommend

Motors do not work no matter what i try including writing my own scripts and using the ones you have provided. i just tested the speaker and it blew and now everytime i use it is causes a short and make my raspberry pi switch off. many times when i turn on the device it does not power the raspberry pi correctly and causes a power issue. it does not work and seems it will even damage my device. Amazon also refunded without me having to send the product back. Reading everyone else's reviews I guess it is safe to say they intentionally sent me a faulty product.
