Got an ESP32-CAM with USB & CH340—Does Anyone Have the Schematic?

[rifat.projects]

Hi everyone,

I recently bought an ESP32-CAM module from an online store, and I found it quite interesting because unlike the traditional ESP32-CAM boards (which require an external USB-to-TTL programmer), this one actually comes with an onboard Micro USB port and a CH340 USB-to-serial converter.

It’s definitely more convenient, but I haven’t been able to find the schematic for this particular board.

Does anyone have the schematic or know where I can find it?

Thanks in advance!

There are several CAM boards that use the CH340 USB-serial converter.

Can you post photos?

The camera connection will likely be the same as that of the Ai Thinker ESP32Cam.

Code: Select all

#define CAM_PIN_PWDN  32
#define CAM_PIN_RESET -1 //software reset will be performed
#define CAM_PIN_XCLK   0
#define CAM_PIN_SIOD  26
#define CAM_PIN_SIOC  27

#define CAM_PIN_D7    35 // Y9
#define CAM_PIN_D6    34 // Y8
#define CAM_PIN_D5    39 // Y7
#define CAM_PIN_D4    36 // Y6
#define CAM_PIN_D3    21 // Y5
#define CAM_PIN_D2    19 // Y4
#define CAM_PIN_D1    18 // Y3
#define CAM_PIN_D0     5 // Y2
#define CAM_PIN_VSYNC 25
#define CAM_PIN_HREF  23
#define CAM_PIN_PCLK  22

Be careful of the cameras on board.
'OV2640' supports 'PIXFORMAT_JPEG', while 'OV7670' is compatible with 'PIXFORMAT_RGB565'.

Oh!!! Nice this look quite convincing!
