I look for a Arduino expert to design a PCB LowPower with:
- mini as a base or other
- XBee (ZNet 2.5 or ZB) for mesh
- Between 1 and 2 sensors 4FS each 5V / 5mA, each book matrices 16 * 16
We seek an expert who exhibits a prototye and plans (Eagle, for example) for a range of autonomy near 1 year, with battery and use available Monday to Saturday from 9h to 20h and 4fps during those hours and those hours are XBee Communications used every 5 minutes to delivering matrice.
The BLE is used only during the first 5 minutes of installation.
We can give more details by MP.
Do you have the battery and sensors already picked out? If so it would probably help to post the links so that people can gauge the viability of running the system for what I'm calculating to be around 4500 hours on a single charge.
First thank a lot for your helpfull.
Yes the sensor has been selected, and are very unique, so we don't have the choice.
For the battery we work with a good compagny, exprt in battery design.
And YES, your screenshot of salsaduino is a very good starting: It seem you are found here: ?? Cross Roads Electronics
a downside, I do not know if the card is designed to be low power, ultra low power?
Have a brief idea of consumption.
So do you know a person which can realize a quotation around the short description. We have a full description of PCB that we looking for to build, which can be sent in MP.
Again thanks a lot "CrossRoad" and "Arrch".
Yes, that's my website.
Can be designed for whatever you want. '328P, '1284P, 4 MHz, 8 MHz, 3.3V, can add switching power supply, etc.
That one used a MIC5219-3.3 regulator to bring LiPo battery to 3.3V for the Xbee and the uC,
and a MCP73831 to control charging of the battery from USB or from Solar Panel
