3V low voltage micro bit servo/Intentions of design

Almost all the micro bit servo in the market have to be driven by 5V, but the normal working voltage for micro:bit is 3V. It is embarrassing to drive a 5V servo with a micro:bit. Thus, we have customized these two servos that can be driven by two batteries with the lowest working voltage at 2.7V. It is the first batch of the micro bit servo designed for the micro:bit in the market.
