The e07-m1101d is a containing the CC1101 chip, crystal, matching network, and antenna connector. The pinout refers to the module’s pads, not the IC’s bare pins.
Understanding the precise electrical mapping and wiring constraints of the 8-pin connector is critical to establishing a stable data link and preventing hardware degradation. E07-M1101D Pinout Assignment e07-m1101d pinout
The ESP32 is an excellent match for this module because it uses 3.3V logic throughout, allowing for a direct and simple connection. The example below uses the ESP32's default SPI pins (VSPI): The e07-m1101d is a containing the CC1101 chip,
The Chip Select Negated pin allows the master (MCU) to enable or disable the E07-M1101D on the SPI bus. e07-m1101d pinout
