E07-m1101d Pinout

| Parameter | Min | Max | Warning | | :--- | :--- | :--- | :--- | | | 0V | 3.6V | Exceeding 3.6V will cause permanent damage. | | Input Power | - | 10dBm | Exceeding this close range may cause damage. | | Operating Temp | -40°C | +85°C | Industrial grade. |

The CC1101 can be sensitive to power noise. If you experience intermittent connection issues, solder a small 10µF capacitor across the VCC and GND pins of the module.

The module is strictly 3.3V. Providing 5V to the VCC pin will damage the CC1101 chip. Ensure a stable supply. e07-m1101d pinout

The Raspberry Pi uses 3.3V logic, making it a perfect match for the E07-M1101D. Connect the SPI pins to the Pi's hardware SPI interface (e.g., pins 19 (MOSI), 21 (MISO), 23 (SCLK), and 24 (CE0)), after enabling SPI in the raspi-config tool.

Manufactured by Ebyte, the is a highly popular, low-cost Sub-1GHz RF transceiver module based on the reliable Texas Instruments CC1101 silicon. It operates across the 387MHz to 464MHz spectrum, making it a staple for 433MHz ISM band applications. It is widely used in smart home automation, remote control clones, weather stations, and IoT sensor arrays. | Parameter | Min | Max | Warning

General Purpose Digital Output 0. Emitted for packet status, TX/RX threshold FIFO interrupts, or clock outputs. CSN

The module typically features an 8-pin interface. Understanding these pins is critical for interfacing the module with microcontrollers like Arduino, ESP32, or STM32. Pin Number Description VCC Power Supply (Typical 1.8V to 3.6V DC). 2 GND Ground connection. 3 SI SPI Data Input (MOSI). 4 SCLK SPI Clock Input. 5 SO SPI Data Output (MISO). 6 GDO0 General Digital Output 0 (configurable). 7 CSN Chip Select Not (Active Low). 8 GDO2 General Digital Output 2 (configurable). Key Specifications | The CC1101 can be sensitive to power noise

(Note: On some versions of EBYTE modules, Pins 5 and 6 might be labeled as DATA/CLK or DI/DO if they operate in SPI mode. However, the "D" in M1101D usually signifies a built-in MCU for UART serial transmission, making TXD/RXD the correct interface for standard usage.)
