M5Stack ESP32 PSRAM Timer Camera (OV3660)

The M5Stack ESP32 PSRAM Timer Camera (OV3660) is a low-power ESP32 camera module with 8MB PSRAM, a 3MP OV3660 sensor, and RTC sleep/wake support, ideal for wireless image capture, remote monitoring, and battery-powered IoT projects.

---

The M5Stack ESP32 PSRAM Timer Camera (OV3660) is a camera module based on the ESP32-D0WDQ6-V3, equipped with an onboard 8MB PSRAM and a 3MP camera (OV3660) with a DFOV of 66.5°, capable of capturing photos at resolutions up to 2048x1536.

It features a status indicator and a RESET button, focusing on ultra-low power consumption design. Through the RTC (BM8563), it supports timed sleep and wake functions, with sleep current as low as 2μA. The board has a reserved battery connector for user-supplied battery power.

The module supports Wi-Fi image transmission and USB port debugging, with a bottom HY2.0-4P port output for connecting other peripherals. Using M5Burner to flash the firmware, the Timer Camera can be configured directly via Camera-Tool, or the data can be processed in UiFlow.
