Arduino Pro Mini Power Supply

Oring for arduino mini pro.

Arduino pro mini power supply.

The maximum current draw of the arduino is 200ma. What is the the max current for power up arduino pro mini 5v 16mhz. Can somebody put here scheme for power up pro mini 5v with transformerless adapter only 4 diodes to make ac to dc and other parts of electronic that is needed in scheme. After reset the control executes the program and provides the desired output.

If you do not want to use any power saving modes and do not need a 5v supply you should word with the arduino pro mini 3 3v. Powering an arduino pro mini 5v and a 3 3v nrf24l01 transceiver from one small battery. To upload adjust the processor in the arduino ide when uploading code to the 5v version board. The lowest reference current consumption has the arduino pro in the 3 3v version with 5 13 ma.

However you can still use this as a guide to upload code for arduino pro mini 5v 16mhz. Provide the power and attach the necessary peripherals. This tutorial was written originally written for the arduino pro mini 3 3v 8mhz. Arduino pro mini 2d model.

The arduino pro mini can be powered with an ftdi cable or breakout board connected to its six pin header or with a regulated 3 3v or 5v supply depending on the model on the vcc pin. Burn the program to pro mini through ide. Customzing the arduino mini pro 3 3v 8mhz. Arduino pro mini is open source hardware.

Without a lot of work it s easy to save power with the arduino pro mini. In power down state running at 8mhz seems to consume as much power as at 1mhzhowever in active state running at 1mhz saves a lot of power 3 5ma to 1ma at 3 3v and around 500µa at 1 8v it is not possible to run at 1 8v and 8mhz to be able to use the battery as most as possible it is mandatory to run. What component can i remove from the original circuit. The arduino pro mini can be powered with an ftdi cable or breakout board connected to its six pin header or with a regulated 3 3v or 5v supply depending on the model on the vcc pin.

You can build your own board using the follwing files. Eagle files in zip schematics in pdf. It s unlikely that the arduino itself will draw 200ma but let s assume that between the arduino and the other devices connected to it they draw a total of 200ma.
