Mini Ultra 8 MHz – Current Consumption (Part 2)

This is the second part of current consumption measurement of Mini Ultra 8 MHz. We’ll show some important steps to put the board into very low power state. The result is well beyond our expectation and we are pretty excited as this marks the completion of one of the main objective of the design. Read more

Mini Ultra 8 MHz – Current Consumption (Part 1)

Current Consumption

At first, we thought of putting the current consumption measurement process of Mini Ultra MHz in one post. However, the post seems to be too long to be fitted into one post. So, here is the 1st part of the current measurement process. Read more

Mini Ultra 8 MHz (Low Power Arduino Compatible Board) – Introduction

Some of you might have came across our earlier design on low power Arduino compatible board going under the name Ultra. We are making a tiny version of the Ultra design – Mini Ultra 8 MHz. Mini Ultra 8 MHz is a simplified and stripped down version of Ultra. Using this board under the Arduino IDE, you can select the board as “Arduino Pro or Pro Mini (3.3 V 8 MHz) w/ ATmega328”. As the name suggest, Mini Ultra 8 MHz is designed to be low power (less than 5 µA in power down mode). Read more

Low Power Arduino – Power Supply

We have to admit that we are a huge fan of Linear Technology. Their product never fails to impress but the only annoying aspect of their product would be price. When designing power supply section, we tend to have this sequence of vendor preference: LT > TI > NI > Microchip > Exar > etc. Read more
