M5CAMERA

Quick Start

Description

The M5Camera is a camera unit based on ESP32 chip and OV2640 including PSRAM. You can even program it through ESP-IDF or Arduino IDE.

There are two versions of M5Camera Unit: A Model and B Model.

This Unit reserves the weld of the 9-axis gyroscope (MPU6050), Temperature and humidity pressure sensor (BME280) and Digital silicon microphone (SPM1423). If you need those devices, you can Self-weld them or purchase those version thraightly. Additionally, M5Camera also reserves the weld of battery.

Note: M5Camera is named differently when different hardware is selected. They follow the rules below.

M5Camera_#_#... means optional hardware name follows "M5Camera".

  • If configured with MPU6050, will be named M5Camera_6050
  • If also configured with microphone, will be named M5Camera_6050_MIC
  • If also configured with BME280, will be named M5Camera_6050_MIC_BME280

NOTE:

  1. Camera Power Down pin does not need to be connected to ESP32 GPIO. Instead it may be pulled down to ground with 10 kOhm resistor.

  2. We have several kinds of camera boards, the following figures show the main differece with them. If you want to view the detailed defference with them, please click here.
