Some integrations, like the "ESPSomfy-RTS" project, use a different mapping. A working alternative for an ESP32 Dev Kit is: GDO0→GPIO 4, CSN→GPIO 13, SCK→GPIO 14, MOSI→GPIO 15, MISO→GPIO 16, GDO2→GPIO 36.
The E07-M1101D is controlled entirely through the SPI bus, a standard synchronous serial communication interface. e07-m1101d pinout
: Some e07-m1101d modules have an 11th pin (labeled “GND”) at the bottom center for mechanical stability and improved grounding. Electrically, it is identical to pins 1 and 10. Some integrations, like the "ESPSomfy-RTS" project, use a
Master Out Slave In. Carries serial data from the microcontroller to the RF module. MISO / GDO1 : Some e07-m1101d modules have an 11th pin
