8Servos HAT v1.1
Description
8Servos HAT v1.1 is an 8-channel servo driver module that works with the M5StickC/C Plus series. Adopt STM32F030F4 as main controller to drive servos with PWM (Pulse Width Modulation) signal. I2C communication. Embedded power management circuit to control servo ON/OFF with programming. With the rechargeable 16340 lithium battery (with the capacity of 700mAh),It also supports 18350 lithium batteries, it can support Maximum 1.3A load. Applied for robotic and DIY projects.
