SunFounder ESP32 Starter Kit
• Firmware can configure register bits to change the settings of “Voltage of Internal LDO (VDD_SDIO)” and
“Timing of SDIO Slave”, after booting.
• The module integrates a 3.3 V SPI flash, so the pin MTDI cannot be set to 1 when the module is powered up.
5.2 ESP32 Camera Extension
We have designed an expansion board that enables you to fully utilize the camera and SD card functionalities of the
ESP32 WROOM 32E. By combining the OV2640 camera, Micro SD, and ESP32 WROOM 32E, you get an all-in-one
expansion board.
The board provides two types of GPIO headers - one with female headers, perfect for quick prototyping projects. The
other type features screw terminals, ensuring stable wire connections and making it suitable for IoT projects.
Additionally, you can power your project using a single 3.7V 18650 battery. If the battery runs low, you can conveniently
charge it by simply plugging in a 5V Micro USB cable. This makes it a great tool for outdoor projects and remote
applications.
