ESP-EYE Circuit components The list and figure below describe the key components, interfaces, and controls of the ESP- EYE development board: 3D_PIFA Antenna A 3D PIFA antenna is used for this module, The antenna gain is 2.98dBi. ESP32 Chip A 2.4 GHz Wi-Fi and Bluetooth combo chip Crystal Oscillator Provides an external clock for ESP32. Espressif 2019.01

! Flash & PSRAM Provides memory to store applications. CP2102 USB-to-UART Chip Converts the USB signals to UART signals. AL USB Port Provides the power supply to the whole system. LDO Power Supply Provides the required power supplies to the ESP32 chip, camera and LED indicators. TI Side Tactile Button A function key Top Tactile Button N Reset/Boot button. We recommend that you do not configure this button for other uses. LED Indicators The board has a red indicator and a white indicator. Different combinations of red and DE white indicators reflect the different status of the board, such as waking up, networking, face detection, face recognition, face enrollment, and face recognition... Camera An external 2-million-pixel camera module for face detection, face recognition and Face ID enrollment FI Camera Connector Used to connect the external camera. MIC N A digital microphone for voice control functions SPI Port A reserved port for data transmission O C Espressif 2019.01
