hi folks ! 😉
no worry, more „hi-fi“ is coming in the next weeks but found today by chance this little thing->ESP32-CAM-MB USB Programmer !
should save the trouble in connecting the ESP32-cam-board via a ftdi-programmer (Essabre-Link here->http://essabre-90xx-rpi.sfb2.com/?p=2269) and reset/uploading a sketch/put in flashing-mode..
u can get them everywhere on ebay or aliexpress for example->https://de.aliexpress.com/item/1005002265308564.html (guess 2$/6$ with ESP32Cam-board)
Nice tutorial in using it is again on „randomnerdtutorials.com/“->https://randomnerdtutorials.com/upload-code-esp32-cam-mb-usb/
and also nice tutorial again to install the Arduino-IDE + the esp32-packages->https://randomnerdtutorials.com/installing-the-esp32-board-in-arduino-ide-windows-instructions/
UPDATE: had problems in streaming with the „normal“ „ESP32-cam-webserver“-.ino in the Arduino-IDE examples-folder to more than 1 client->this library (rtos-based) should do the trick (up to 10 devices)->https://github.com/arkhipenko/esp32-mjpeg-multiclient-espcam-drivers
so, many greets for now and as said more „hi-fi“ / ES90xx/Pro -things are coming again in the next weeks !! 😉
