GPIO1 and GPIO3 has alternate functions for the serial transmission and reception of the data for UART port, respectively. Similarly, to turn off LED, we drive GPIO 33 to active high state.Īlmost all the GPIO pins of ESP32-CAM are multi-purpose pins. That means if we want to turn on LED, we drive GPIO 33 to logic low level. This built-in red LED is connected with GPIO 33 in logic low active state. You can find this LED next to the reset button. GPIO33 – Built-in Red LEDĪI-Thinker board also has one onboard RED LED. According to Jumper connection on ESP32-CAM, VCC pin provides 3.3V output. This is a VCC pin that can output either 5V or 3.3V. Power Output PinĮSP32-CAM also provide one power output pin as shown in yellow color in the pinout diagram above. But it is recommended not to power this development bord with 3.3V pin, it does not provide stable power to board. These pins can be used to power the ESP32-CAM AI-Thinker module. The module has three ground pins and two positive power supply pins such as 5V and 3.3V pins. The ESP32-S chip has a total of 34 pins but only 16 pins are exposed to the pinout headers. This section describes the pinout of the ESP32-CAM AI-Thinker Module. Furthermore, it is quite durable and reliable when it comes to internet connectivity.

The module has a maximum clock frequency of 160 MHz that means the computing power up to 600 DMPIS. The module has an inbuilt Hall sensor, temperature sensor, and touch sensors, and watchdog timers.

The ESP32 IC has high-resolution ADCs, SPI, I2C, and UART protocols for information communication. PeripheralsĮSP32-CAM has integrated with Wi-Fi, Bluetooth and can be used with OV2640 or OV7670 cameras. The ultra-small, low-power module comes with two high-performance 32-bit LX6 CPUs with a 7-stage pipeline architecture. ESP32-CAM AI-Thinker is the advanced version of ESP8266-01 launched by Espressif with many features. ESP32 Series chips are one of the popular intelligent modules for IoTs. From the hobbyists to the innovators, everyone is interested in Smart technology, designing different prototypes and products, and launching them in the market. The world has been revolving around IoTs i.e., Internet of Things for quite a while now. We will discuss pinout, features, specifications and see how to get started with ESP32- CAM development board. This tutorial is a guide to AI thinker ESP32-CAM development board.
