chip, which handles communication between your computer's USB port and the ESP32's UART pins (GPIO 1/TX and GPIO 3/RX). Auto-Reset/Program Circuit : Unlike a standard FTDI adapter, the MB board uses the DTR and RTS signals from the USB chip to automatically toggle the (GPIO 0) and
Before diving into individual components, let’s understand the big picture: esp32-cam-mb schematic
| MB Pin | ESP32-CAM Pin | Function | |--------|---------------|-----------| | 1 | 5V | 5V power in | | 2 | GND | Ground | | 3 | IO0 (GPIO0) | Boot mode | | 4 | IO16 (GPIO16) | Not used by MB | | 5 | EN (CH_PD) | Reset | | 6 | U0R (TX) | Serial TX from ESP | | 7 | U0T (RX) | Serial RX to ESP | esp32-cam-mb schematic
