IoT Carrier v0.1
Overview
IoT Carrier v0.1 is a modular sensing platform designed to support multiple ESP32 development boards through a standardized hardware interface.
The carrier board integrates power management, analog sensor inputs, I²C communication interfaces, and dedicated connectors for environmental sensing applications.
The platform allows different ESP32 boards to be exchanged without hardware redesign, simplifying prototyping, firmware development, and testing.

Programming Power Supply Note
- Power the ESP32 board only through its own USB programming connector.
- The USB-C connector on the IoT Carrier PCB is power only and does not support data communication.
- Disconnect the Li-Po battery and any external power source before firmware upload.
- Use a USB cable that supports data communication.
- Select the correct ESP32 board profile and COM port in the Arduino IDE.
