Devlog - 7

so finally I am done with all this pcb designing thing
exported the files into gerbers,png,step file type

next steps
push these files to github repo
submit project for grant on stardance
Thank you for your attention to this matter

Dev log-6

Finally done with PCB design of relay node and vehicle node.
yet to push design files on github.

It becomes hard to route manually for me so i end up doing autoroute in the end.

I used reference design from datasheets to make it easy for me to follow and make this pcb design.

next steps
-PCB Design for Gatewaynode
-Push all files to github
-Start designing Enclosure for each node

Devlog -5

Turns out my last PCB design for vehicle node had many flaws.

1. No filtering near power inputs
2. No SIM socket for GSM module 😭(the classic blunder)
3. Power regulation issues(using external buck converters while i could design it on my own)
4. Assumption of using 2S Li-ion would be minimum necessity .

So far I have fixed the followings

1. Power regulation for GSM,GPS,ESP,MPU,LoRa
2. Added sim socket(working on its connection)

Next steps

1. Connect SIM Socket
2. Add power key circuit
3. Add Reset button for GSM
4. Figure out if anything else to add for GSM
5. Make relay node schematics
6. Make GatewayNode schematics

Was working on documentation part of the project

did some changes in README.md file
and spent a lot of time in making BOM
it took time to find out components and there prices required to prepare BOM.

PCB Designing and Documentation.

1. Rearranged schematics for Vehicle Node.
2. Revised PCB design for Vechile Node.
   3.Made schematics for Relay Node.
3. Designed PCB for Relay Node.
4. Added files ( gerber , pcb image, schematics pdf) to repo.

designed schematics and pcb for vehicle node( not a final design..it need some more work)

working on code part and setting up github repo
made 3 code files for 3 Nodes
added basic structure of each files(setup and loop function)
added crash detection function in vehicle node
next- make schematics & update READ.md
