TimerCamera

SKU:U082

Description

TimerCamera 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 TimerCamera can be configured directly via Camera-Tool, or the data can be processed in UiFlow.

Learn

The low-power power management solution used by the Timer Camera series is different from that of CORE and StickC devices. The PWR button is used as the power-on button (long press for 2 seconds). To power off the device, you need to use a software API or press the reset button on the PCB. When using external power, the device will remain powered on.

Quick Start

Arduino

TimerCamera-Arduino

ESP-IDF

Under-voltage / Power-off Protection

When the device is undervoltage, the camera may trigger undervoltage protection, causing a reset.

ESP-IDF

In ESP-IDF, you can configure and disable this in menuconfig when compiling the project.

idf.py menuconfig

Component config -> ESP32-specific -> Hardware brownout detect & reset (disable)

Arduino

On the Arduino platform, you can disable it during initialization with the following sample code:

#include "soc/soc.h"
#include "soc/rtc_cntl_reg.h"

void setup() {
  WRITE_PERI_REG(RTC_CNTL_BROWN_OUT_REG, 0); // disable detector
} 

USB Driver

In some systems, TimerCAM may not work without a driver. You can fix this by manually installing the FTDI driver. For example, in a Windows 10 environment, download the driver file that matches your OS, extract it, and install it via Device Manager. (Note: In some system environments, you may need to install the driver twice for it to take effect. The unrecognized device name is usually M5Stack or USB Serial. For Windows, it is recommended to install the driver file directly in Device Manager (custom update). The executable installer method may not work properly).
