This is an adaptor PCB for the ESP32-CAM. The ESP32-CAM does not come with USB and requires a FTDI adaptor to program it. Normally this requires a bunch of Dupont cables and poking around. This PCB makes flashing the ESP32-CAM plug and play. A header is provided to put the device into flash mode while another header lets you choose if you want to flash at 3.3v or 5v. (ensure your FTDI adaptor is set to the same before plug in). The ESP32-CAM can be powered by the onboard Mini USB (chosen as it is a through hole variety and easier to solder) or a via a screw terminal and 5v step down buck converter. This will allow powering the device at much higher voltage levels.
