Timer Camera is a esp32 cam module based on the ESP32 with 8MB of integrated with PSRAM. The 3 million (3MP) pixel camera (ov3660) ,DFOV 66.5 ° and can shoot a maximum of 2048x1536 resolution photos. There is a LED status indicator and reset button on the board. Timer esp32 camera is designed to have ultra-low power consumption. Through the use of the RTC (BM8563), timing, sleep and wake-up functions can be utilized.

In sleep mode, the current consumption of the whole machine is only 2μA. After the scheduled photo taking function(one photo per hour) is turned on, the battery can work continuously for more than one month. The module supports Wi-Fi image transmission and USB port debugging. The bottom HY2.0-4P port output can be connected to other peripherals. In order to facilitate DIY, the battery interface is reserved on the board. Using the M5Burner firmware burning tool, time-cam can be set directly with the Camera-Tool, and TimerCamera data can be processed in UIFlow.

The low-power power management solution adopted by the Timer Camera series is different from the CORE and StickC devices. When in use, the PWR button is used as a power-on button(long press 2s). If you need to shut down the device, you need to use the software API or press the Reset button on the PCB.When using external power supply, the device will remain powered on.

  • Camera-Tool is suitable for TimerCAM and UnitCAM series products. The GROVE interface needs to be connected to the PC through the TTL-TO-USB adapter board before UnitCAM is used.
    Use TimerCAM to achieve low-power wake-up shooting function, which requires Wi-Fi connection. The captured pictures will be automatically uploaded to the M5 cloud, and a fixed HTTP interface will be generated through a unique token, and other devices can access through this interface to obtain the latest frame of pictures and the current battery voltage status of the device
    Use M5CORE type equipment to connect TimerCAM/Unit CAM through GROVE interface to realize command to control the camera UART to transmit images and preview them on the M5CORE screen, or configure the timer shooting upload cloud function (return to fixed HTTP API).

    Love it. Will order many more. Please don’t discontinue it!

    This board is perfect for my needs. The power management for long term deep sleep / shut down is very hard to find anywhere else. Please don’t discontinue this board any time soon, I’ll be ordering thousands more over the coming years for my smart sensor product!

    Delivery was quick as usual. Thank you very much. The Timer Camera works just fine, although I noticed it gets quite hot.
