A remote datalogging system with many connectivity options.
Based upon the LinkIt One system on a chip board:
PCB has been designed in KiCAD and the files are available in this repository.
PCB has 2 x DC DC converters and a LiIon charger for recharging the battery.
3 x ACS1115 16 bit ADCs are used for monitoring the data.
The software has been written in C for upload via the Arduino IDE.
A configuration file is used on the SD card which lets the unit know how it needs to work. Set up can easily be done 'in the field'.
