8Servos HAT

SKU:U076

Description

8Servos HAT is an 8-way servo control board compatible with M5StickC. The brains of the borad is the STM32F030F4 micro controller 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.
