ATmega328P Microcontroller SMD IC 50V The XL4015 power module isATmega328P Microcontroller IC is the high performance Atmel Pico Power 8 bit AVR RISC based microcontroller. It has an SMD package that has 32K of program space, 23 I O lines, and 8 of which are channels for the 10 bit ADC. It runs up to 20MHz with an external crystal. Its package can be programmed in circuit and 1. 8V to 5V operating voltage. This is the same microcontroller that is used in Arduino Nano. So, we can use this micro controller and load
