TimerCamera

SKU:U082

Description

TimerCamera is a camera module based on ESP32-D0WDQ6-V3, with onboard 8M PSRAM, using a 3MP camera (OV3660), DFOV 66.5°, capable of capturing photos with a maximum resolution of 2048x1536. It features a status indicator and a RESET button, designed with ultra-low power consumption in mind. It can achieve timed sleep and wake-up through RTC (BM8563), with a sleep current as low as 2μA. The board has a reserved battery interface, allowing users to connect a battery for power supply. The module supports WiFi image transmission and USB port debugging, with a bottom HY2.0-4P port output for connecting other peripherals. By flashing the firmware through M5Burner, users can directly use Camera-Tool to configure TimerCamera, or process TimerCamera data in UIFlow.

Learn

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

Quick Start

TimerCamera-Arduino

ESP-IDF

Undervoltage/Power Loss Protection

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

ESP-IDF

ESP-IDF can be configured in menuconfig during project compilation to disable this feature.

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 example 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

TimerCAM may not work plug-and-play on some systems. Users can manually install the FTDI driver to fix this issue. For example, in a Windows 10 environment, download the driver file matching the operating system, extract it, and install it through the Device Manager. (Note: In some system environments, the driver may need to be installed twice to take effect. The unrecognized device name is usually M5Stack or USB Serial. Windows recommends using the driver file to install directly in the Device Manager (custom update), as the executable installation method may not work properly).
