ULPNode Low Power Secret Revealead

ULPNode Low Power

After several articles and some intensive tests with ULPNode, it’s now time to explain how the low power engine has been built. Even if you can find plenty of Arduino clone node, when it’s time to power them with battery… Continue Reading


ULPNode first prototypes status

ULPNode 1st Proto PCB

Today I wanted to do a quick project status of the 1st prototype of ULPNode I received some days ago. After the introduction of ULPNode, and both articles about  bootloader (1 and 2) used, for this one I will start with… Continue Reading


Implementing Bootloader for Ultra Low Power Arduino Wireless Sensor Node : Part 2

ULPNode Fuses settings

Following the 1st part of bootloader description for ULPNode this article describe what modification have been done to optiboot to be able to drive new Ultra Low Power nodes. Optiboot For this, I started from original optiboot (latest trunk from google code)… Continue Reading


Customized Bootloader for Ultra Low Power Arduino Wireless Sensor Node : Part 1

ULPNode Bootloader Testing

Following the previous article presenting the ULPNode it’s now time to deep into the technique used to setup the starting mechanism of ULPNode bootloader. In this 1st part I’m introducing the goals to achieve and in the 2nd how it has… Continue Reading


Be prepared to new Ultra Low Power Arduino Wireless Sensor Node

ULPNode Early Prototypes

Why this new project ? For some time being, I researching a way to have to have a kind of “universal” Arduino node sensor. When I say universal, I’m talking about connecting to it several sensors type (Temperature, Humidity, Lux,… Continue Reading


Use RFM12B, RFM69, Micro SD or Flash EEP using ArduiPi NRF24L01 connector

Use RFM12B, RFM69CW, RFM69W or RFM69HW, Micro SD or Flash EEP with NRF24L01 connector of ArduiPi board (or other) Updated 2014 September I created 3 other small boards, V1.2 without SD but very small, the V1.2 SMD ultra small (version… Continue Reading
