Review of PCB designs

Have a look at this PCB design: ~https://labnotes.ncbs.res.in/bhalla/mousebehaviour-cad-files-release-20190707pre2~ https://github.com/BhallaLab/MouseBehaviour/releases/tag/v20190707.rc1

Eyeball the schematic at link above. Let me know if you notice something odd/missing. Tomorrow evening, @mrdorababu is going to drill couple of PCBs.

IMP Required components are here: https://github.com/BhallaLab/MouseBehaviour/releases/download/v20190707.pre2/BOM_MouseBehaviour.xls . This sheet contains component required to make 1 PCB.

Please place the order as soon as possible for as many PCB as required. My BOM on [mouser.in] is here: https://www.mouser.in/ProjectManager/ProjectDetail.aspx?AccessID=68514497ae . If you have mouser accounts, I can share the project with you guys.

Both GPIO are optional. They support CAMERA TTL pulse for blackfly. They usually have GPIO 6pins port. We can also use 2-pin connectors as well.

• J5 and J6 are complementary to GPIO females J10 and J11.
• J4 and J12 are complementary.

Notes from @mrdorababu

1. The diode which is connected in the solenoid driver need to be in reverse bias. So we need to connect -ve to the 12V.
2. The AGND and DGND are shorted in the PCB. We need to isolate DGND and AGND.

@soumyaaymous @ananthamurthy @hrishi16 reminder. I'd be nice to have one review before it goes to Fab today.

[hrishi16]

To whatever extent I know, this should be fine.

[ananthamurthy]

Seems ok.. let's proceed

[dilawar]

This will go for fab.

Got one made today. I will soldier/mount the components tomorrow morning in workshop. The components needs to be ordered. I've not heard from anyone about order yet. Assuming someone is on it.

Release v2019.07.09.rc1 has thicker tracks.
