How to design and develop a power supply for an arduino clone

INTRODUCTION AND SCOPE

An Atmega 328P without arduino board can achieve the same capabilities of the arduino board, using the same arduino IDE programming and coding environment. Using an Atmega 328P chip without arduino board is powerful, cheap and functional. For a fully standalone setup, this requires a dedicated power supply. This procedure explains how to design and develop a power supply for an arduino clone.

MATERIALS AND EQUIPMENT

DC/DC Step-up Converter with USB 5 Volt output, 3D printed Flexing battery case (1 or 2 battery slots), 1 or 2 AA batteries, Wiring, Soldering.

PROCEDURE

  1. Wire and solder the USB power and ground pins on the DC/DC Step-up Converter with USB 5 Volt output (Hardware resources, link 1) (Image 2). The recommended DC/DC Step-up Converter can take as an input a voltage between 0.9 and 5 Volt and gives an output of 5 Volt with 500mA (when connecting 2 AA batteries) or 200mA (when connecting 1 AA battery)
  2. Wire and solder the battery power and ground pins on the DC/DC Step-up Converter with USB 5 Volt output (Hardware resources, link 1) (Image 1).
  3. 3D print the flexible battery case according to the recommendations at the provided resource (Hardware resources, link 2). The suggestion is to print single battery cases (1 or 2 depending on requirement)
  4. Wire the flexible battery case(s) in series to the battery power and ground pins on the DC/DC Step-up Converter with USB 5 Volt output (Image 1)
  5. Insert the charged AA battery into the flexible battery case(s)
  6. Provide power supply from the USB power and ground outputs of the DC/DC Step-up Converter to the standalone Atmega 328P (Hardware resources, link 3)
