# Goal
|
|
|
|
|
|
|
|
The datalogger designed to monitor photovoltaic water pumping systems in remote areas, like the village of Gogma in Burkina Faso, Because these villages are off-grid, the Datalogger is supplied by batteries and photovoltaic (PV) panels.
|
|
|
|
The idea is to build an openSource tool, which is simple, robust annd cheap.

### PCB
|
|
|
|
|
|
|
|
* Dimension 10x10 cm
|
|
|
|
|
|
|
|
* SMD components only
|
|
|
|
|
|
|
|
* Passive components not below 0805 casing to ease manual repairs
|
|
|
|
|
|
|
|
* IC not below 1.27 mm pitch
|
|
|
|
* Dimension 20x20 cm
|
|
|
|
|
|
|
|
* Only widely available component references
|
|
|
|
|
|
|
|
* Use components available on LCSC distributor
|
|
|
|
|
|
|
|
* Up to 4 layers with vias
|
|
|
|
|
|
|
|
* Standard copper thickness (1 oz)
|
|
|
|
|

|
Note 1: Using only widely available components is important to ensure that we do not suffer from chip shortage and that people across the world can source components locally to repair the devices.
|
|
|
|
|
|
|
|
Note 2: Using components available on LCSC distributor makes it possible to source all the components directly from a PCB manufacturer pre-assembled without the need of soldering every small components. This would help keep it low cost and integrated with the chinese manufacturing ecosystem.
