Budget: 12000 UAH Deadline: 5 days
Good day. It would be interesting to work on your project. I think it can be done in a few days. The cost is $300.
Overall, the approach is correct. We will try to make everything as simple as possible. Regarding the SDK documentation - there is no need to worry. The most difficult part will be to make the application able to insert text into Chrome.
I have worked with lock opening boards, battery chargers, and BMS modules - I can show you if you are interested.
