E07-m1101d Pinout

: Module gets hot, no communication, eventual failure. Fix : Use a level shifter or select a 3.3V MCU.

Connect to 3.3V and GND. Important: The module operates at 3.3V. Connecting to 5V will destroy the device.

Before examining the pinout, let’s briefly review the module’s key specifications: e07-m1101d pinout

Understanding its pinout is critical for correct integration, as incorrect wiring can damage the module or degrade RF performance.

#include <ELECHOUSE_CC1101.h>

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.

While the Arduino Uno operates at 5V logic, the E07-M1101D is a 3.3V device. You must use a on the SPI lines (CSN, SCK, MOSI). The MISO line from the module is 3.3V, which the Uno can typically read as HIGH, but a level shifter is still recommended for safe and reliable operation. : Module gets hot, no communication, eventual failure

The e07-m1101d’s pinout is standard for most SPI-based wireless modules. Here’s how to connect it to popular platforms:
