Description:

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. 

Product Features:

  • 8-way servo control
  • onboard RGB LED
  • 16340 battery base
  • I2C protocol for comunication and control

Weight and Size:

  • Size: 55mm * 25mm * 20mm
  • weight: 33g(include battery)

Applications:

  • Multiple servo control
  • Robotic Arm
  • Biomimetic Robots
  • Smart and cognitive toys

Package Included:

  • 1x 8Servos-HAT
  • 1x 16340 battery

EasyLoader:

  1. EasyLoader is a simple and fast program burner. Every product page in EasyLoader provides a product-related case program. This can be burned to the M5 device through simple steps, and a series of function verifications can be performed.
  1. After downloading the software, double-click to run the application, connect the M5 device to the computer through the data cable, select the port parameters, click "Burn" to burn the program (For M5StickC, set the baud rate to 115200 or 750000)
