All examples in this library are developed based on the ESP-IDF platform, designed for communication between TimerCAM and host computers or data interaction with various cloud services. The demos in this library include the following functions: cloud storage using Ali-OSS, communication with AWS-related cloud services, real-time camera data transmission via HTTP, file transfer to host computers using SMB servers, wake-up function demonstration, and wireless transmission function demonstration.

TimerCAM is an ESP32-based camera module featuring an ESP32 chip with 8MB PSRAM onboard. It uses a 3-megapixel camera (OV3660) with a 66.5° field of view, capable of capturing photos at up to 1600 x 1200 resolution. With status indicators, it emphasizes ultra-low power design. Through the RTC (BM8563), it can achieve timed sleep and wake-up functions, reducing sleep current to as low as 2μA. The board includes a battery interface for users to connect external power supplies. The module supports WiFi image transmission and USB port debugging, with a bottom HY2.0-4P port for connecting other peripherals.

• Adapted for ESP-IDF v5.0 and above
