Here's an image of the ESP32‑S CAM OV2640 module with CH340 USB‑serial breakout—a compact board combining a camera, ESP32 microcontroller, and onboard USB programming interface.
Overview
This module is a development board built around the ESP32‑S, featuring:
-
Dual-core LX6 microprocessor (up to 240 MHz, ~600 DMIPS),
-
Wi‑Fi (802.11 b/g/n) and Bluetooth 4.2 + BLE, with PCB antenna,
-
A 2 MP OV2640 camera (supporting JPEG, BMP, grayscale formats),
-
Onboard CH340 USB‑to‑serial interface via micro-USB, for easy programming without external adapters (Amazon, sigmanortec.ro).
