- Started by experimenting with an Arduino Nano ESP32, quickly programming it via Arduino IDE and later command-line tools.
- Progressed from breadboard prototypes to designing a custom BME280 sensor PCB to move beyond prototyping.
- Used KiCad for schematic and PCB design, learning about component footprints and board layout.
- Sourced components mainly from DigiKey, except for the BME280 sensor which was harvested from an existing module.
- Ordered PCB from JLCPCB, with a low-cost delivery taking 2-3 weeks.
- Assembled the board using a Hakko soldering iron and Quick 861DW hot air station for SMD components.
- Successfully created a plug-and-play custom PCB that worked on the first attempt.
- Gained confidence in PCB design, considering more complex projects integrating LCD, ESP32, and BME280 on one board.
