MicroPython is the recreated version of Python 3 that runs in the memory restricted microcontrollers with a minimum of 256KB of ROM and 16KB of RAM. MicroPython supports chips like ESP32, ESP8266, STM32, nRF52, W600 etc. MicroPython follows Python 3 syntax which makes it easy to programme for microcontrollers.The hardware APIs are capable of handling GPIO pins in microcontrollers. In this course we discuss the ESP32 dev module as the main controller which has a high level of flexibility in connecting with sensors, on chip capabilities with onboard WiFi. In this eBook we will discuss software required,basic Python3 syntax, controllling GPIO pins and connect to internet over WiFi.
