From the project
A JavaScript-driven M5Stack-embedded super-kawaii robot.
Drive two servos PWM 2ch or Serial 2ch M5Unit PortB External 5V Power Supply Battery, which can be charged through M5Stack. * (Optional) Power switch

Pros: Low cost Very low cost (~500yen), easy to find. PortC (serial communication) is available for users.
Cons: Difficult to control and having a (small) safety risk. Difficult to change its angle smoothly. Inrush current is high and may cause the M5Stack to power down in rare cases. SG90 possibly get very hot and may emit smoke when overloaded, such as when the angle exceeds the…
