ESP 32 CAM – MB + EBYTE E19-915M30S

[leonardo begnini]

Hello, I need to connect an ESP 32 CAM with MB in an EBYTE E19 915 mhz, my goal would be to take pictures and send via lora to a gateway.
If anyone can help me with connecting the wires for communication between the two I would be grateful.

Hi Leonardo,
you can use a custom SPI interface with the relative pin

/*
Default SPI
  #define HSPI_MISO   12
  #define HSPI_MOSI   13
  #define HSPI_SCLK   14
  #define HSPI_SS     15

*/

SPIClass * hspi = NULL;
 
void setup() {
   hspi = new SPIClass(HSPI);
 
  //        sck, miso, mosi, ss
   hspi->begin(HSPI_SCLK, HSPI_MISO, HSPI_MOSI, 16);
 }

In the example, I use the same SPI pin but a dedicated CS for activation.
I didn’t test It but I think It’s ok.

As you can see in the pinout on the same SPI pins there is the SD.

Bye Renzo

It is true ?

Hi Leonardo,
GPIO15 is the standard CS, and it’s used for SD, so you must change it.
