LilyGO T-Camera Plus ESP32 Camera Module w/ 1.3-Inch IPS Display

Connect the board via its micro-USB port to your PC. Install the ESP32 board package in the Arduino IDE or set up ESP-IDF. Select the correct COM port and upload your sketch. The onboard CP2104 chip handles USB-to-serial conversion. For camera and display examples, use the T-Camera Plus library from the LilyGO GitHub repository to initialize the OV640 sensor and ST7789 screen.

The core logic operates from 2.3V to 3.6V, typically supplied by the 5V USB input. The board supports an optional 3.7V lithium battery connected via its JST connector for portable use, with an integrated charging circuit. Average operating current is around 160mA, but this increases with wireless transmission and display activity. For extended battery life, utilize the ESP32's deep sleep modes between capture cycles.

Use the provided camera library to initialize the OV640 sensor over its parallel interface. Capture frames into a buffer. To display the image, use the ST7789 driver library to write the buffer to the IPS screen via SPI. For wireless streaming, implement a web server on the ESP32 to serve JPEG images over Wi-Fi. Example code typically includes functions for both local display and HTTP streaming to a browser.
