Summary of the Circuit

This circuit is designed to interface a microcontroller with a motion sensor, a receiver, electronic speed controllers (ESCs), and a power supply system. The microcontroller used is a SparkFun Pro Micro, which communicates with an Adafruit ADXL345 accelerometer and a flysky mini receiver. The ESCs are used to control motors (not detailed in the parts list), and the power supply system consists of a Lipo Battery and a Step Up Boost Power Converter to regulate the voltage. The circuit is designed to be powered by the Lipo Battery, with voltage regulation provided by the Step Up Boost Power Converter.
