Solar PCB v0.2

Here is the Solar PCB v0.2:

Here is the schematic:

cubesatsim-solar-0.2_schematic.pdf

The diodes D1 - D6 and resistors R3 and R4 are installed vertically:

Here is the polarity of the diodes:

They are installed on the PCB top then soldered on the PCB bottom:

Trim the leads after soldering:

On the bottom, install the 1x4 pin header

Use this pin header to test the INA219 boards before soldering and mounting them.

On the PCB bottom, install the GPIO header J1 and three 1x6 female sockets:. Alternatively, after testing the INA219 boards can be soldered directly without sockets.

Flip the PCB to the top and solder.

Install 3 INA219 boards on the bottom:

Here they are installed. Set the jumpers as marked on the PCB.

Install 12 JST 2.0 connectors on the top - there are two for each of the sides of the CubeSat. Apply a drop of superglue to the plastic before attaching them so they will hold together while plugging and unplugging cables:

DO NOT INSTALL a connector for the battery, as the power goes through the GPIO connector.

Install 4 female headers 1x6:

Install 4 INA219 boards on the top:

Here they are installed with the jumpers set per the markings on the PCB.
