E07-m1101d Pinout -

I have written this based on the standard E07-M1101D (an 868/915 MHz SMD wireless module from Chengdu Ebyte). Note: If you meant a different variant (e.g., E07-M1101D-TH), the pinout may differ slightly.

Reset & Antenna

RST (Pin 8): Active low. Connect to 3.3V via a 10kΩ pull-up if not controlled by MCU.
ANT (Pin 11): Solder a 50Ω quarter-wave antenna (e.g., ~8.2 cm wire for 915 MHz) or use a U.FL pigtail.

Unlike standard CC1101 modules that often have 10 pins, the E07-M1101D typically utilizes an 8-pin (2x4) configuration. The core difference is the removal of redundant VCC and GND pins found on larger boards. Pin Mapping Table e07-m1101d pinout

Data:

If you are using an Arduino Uno or Mega, you must use a level shifter on the SPI lines (CSN, SCK, MOSI) or a voltage divider to drop the 5V signals to 3.3V. Connecting 5V directly to the data pins can permanently damage the CC1101 chip. Essential Tips for Success I have written this based on the standard

The E07-M1101D is a compact 433MHz wireless module based on the Texas Instruments CC1101 transceiver chip, typically featuring an 8-pin DIP (Dual In-line Package) layout. Pinout Configuration RST (Pin 8): Active low
