8Servos HAT is an 8-way servo control board compatible with M5StickC. The brains of the borad is the STM32F030F4 microcontroller which communicates with M5StickC through I2C. In order to ensure that multiple servos can work at the same time, the HAT is equipped with a separate 16340 battery base for an external and independent power supply. A control switch and an RGB LED are also integrated with the HAT. The SG90 servos are a perfect fit for this HAT.
It has RGB LED which is fun to play with. Battery is handy too. So far, I have tested it with SG90 servos and it works as expected. I like this a lot. I only haven't figured out how to check the battery status.
It's a very good and fantastic product in really!!!
