## 2022-09-13: Meeting-Notes
Discussed with TA regarding our project proposal and our system and subsystem designs. Some things and suggestions to take note of:
- Add subcomponents for the cloud server for block diagram.
- Label necessary voltages at each power line for block diagram.
- Expand high-level requirement involving power to include 24-hour availability while the board is plugged in.
- Don't bother making your own Wi-Fi module; just buy one since budget is $150.

Since we have a limited $150 budget, all of our purchases will most likely be limited to Amazon, Digikey, and Mouser. Parts we are leaning toward using:
- **Control Unit and Radio Scanner Suite**
- [ESP32-S3-MINI-1](https://www.espressif.com/sites/default/files/documentation/esp32-s3-wroom-2_datasheet_en.pdf)
- This ESP32 is versatile, not super expensive, offers various functionalities, and is used in many IoT projects, both hobbyist and professional.
- Furthermore, this microcontroller has been proven to be compatible with AWS.
- Currently, we aren't planning on integrating the 5 GHz frequency into the Radio Scanner Suite due to time constraints. The primary issue is that if we were to also scan 5 GHz, we would need to purchase a separate Wi-Fi module and write the drivers for it, which would take too much time and effort to integrate. So we plan on settling for 2.4 GHz frequency for our Wi-Fi module for now
- [USB-to-UART Bridge](http://esp32.net/usb-uart/): We need to make use of this bridge and attach it to our ESP-32.
