## Description

|
||||
**<mark>ESP32Cam</mark>** is a tiny unit based on ESP32 chip and OV2640. You can even program it through ESP-IDF. But to compare with [M5Camera](m5camera.md), ESP32CAM <mark>does not integrates PSRAM</mark>.

**<mark>ESP32Cam</mark>** is a camera unit based on ESP32 chip and OV2640. You can even program it through ESP-IDF. But to compare with [M5Camera](m5camera.md), ESP32CAM <mark>does not integrates PSRAM</mark>.
|
||||
|
||||
The ESP32Cam equips the ESP32 with everything necessary to program, run and develop on the wonderful chip. It also features a LiPo charger , so your ESP32Cam project can be battery-powered and truly wireless.
|
||||
This Unit reserves the weld of the 9-axis gyroscope (MPU6050), Temperature and humidity pressure sensor (BME280) and **analog MIC (SPQ2410)**. If you need those devices, you can Self-weld them or purchase those version thraightly. Additionally, M5CameraF also reserves the weld of battery.
|
||||
|
||||
Additionally, the board reserved the Welding positions of MPU6050,BME280 and an **analog MIC**.
|
||||
**Note: ESP32CAM is named differently when different hardware is selected. They follow the rules below.**
|
||||
|
||||
*ESP32CAM_#_#... means optional hardware name follows "ESP32CAM".*
|
||||
|
||||
* If configured with MPU6050, will be named ESP32CAM_6050
|
||||
* If also configured with microphone, will be named ESP32CAM_6050_MIC
|
||||
* If also configured with BME280, will be named ESP32CAM_6050_MIC_BME280

Because the module can generate WIFI hotspot AP, So you can use your mobile phone, PC or other device to get the camera image wirelessly via WIFI, or wirely via GRVOE interface.
