![]() ![]() Bluetooth: v4.2 BR/EDR and BLE (shares the radio with Wi-Fi).CPU: Xtensa dual-core 32-bit LX6 microprocessor, operating at 240 MHz and performing at up to 600 DMIPS. ![]() To summarize, the ESP32-CAM has the following specifications. It is user-programmable and connected to GPIO33. There is a small red LED on the back that can be used as a status indicator. It is equivalent to Espressif’s ESP-WROOM-32 module (same form factor and general specifications). The ESP32-CAM equips the ESP32-S surface-mount printed circuit board module from Ai-Thinker. Let’s take a look at each component one by one. While the chip’s capabilities are quite impressive, the ESP32-CAM development board adds even more features to the mix. Being an SoC, the ESP32-S chip contains an entire computer-the microprocessor, RAM, storage, and peripherals-on a single chip. The heart of the ESP32-CAM is an ESP32-S System-on-Chip (SoC) from Ai-Thinker. Whether you need to detect motion in your Halloween project, detect faces, decode license plates, or perhaps merely a security camera, it’s worth having one in your DIY toolbox. Amazingly, for less than $10, you get an ESP32 with support for a camera and an SD card. The ESP32-CAM, a board that hit the market in early 2019, has changed the game. If you were asked a few years ago how much a digital camera with WiFi would cost, you probably wouldn’t have said $10. ![]()
