Arducam IoTai - ESP32 UNO PSRAM board

Overview

Arducam ESP32 UNO PSRAM (Arducam IoTai) is an upgrade to its predecessor ESP32 UNO board. It’s a solution to IoT (Internet of Things) and simple AI (Artificial Intelligence) applications based on ESP-32. This board incorporates an external 4MByte PSRAM that enlarges the RAM space and makes image capture and processing possible. The camera interface now can directly connect most of the parallel port cameras without additional hardware, like OV2640, OV7670, OV7725, etc.

The board supports both Arduino IDE and ESP-IDF software development tools, keeps the same form of factors and pinout as the standard Arduino UNO R3 board, and makes the Arduino shields reusable. With the onboard USB to serial chip, it supports firmware one-click-download.

The board is also designed for battery-powered portable devices with its onboard battery charging circuits and supports lithium battery power supply. The SD card slot is an extra add-on for those advanced applications that require larger storage.

Based on open-source face detection and recognition library, it supports face detection and recognition in low frame rate. Its low power feature makes it an ideal solution for home security and IoT camera applications.
