Hat 8Servos v1.1
Description
Hat 8Servos v1.1 is an 8-channel servo driver board compatible with the M5Stick series. It uses the STM32F030F4 main controller to generate multiple PWM signals for servo driving and is controlled via the I2C communication protocol, effectively saving IO resources. It features a servo power control circuit composed of MOS transistors, supporting programmable dynamic control of motor release/lock. The power supply uses a rechargeable 16340/18350 lithium battery (700mAh) and also supports 18350 lithium batteries. The maximum load can reach 1.3A when all 8 channels are working simultaneously, meeting the driving requirements of standard servo specifications.
