The E07-M1101D is a compact, high-performance wireless transceiver module operating in the 433 MHz ISM (Industrial, Scientific, and Medical) band. Developed by Chengdu Ebyte Electronic Technology Co., the module is built around the Texas Instruments chip. The CC1101 is a mature, sub-1 GHz RF transceiver known for its low power consumption, high sensitivity, and versatility, making it ideal for short-range wireless communication systems.
Whether you’re designing a remote sensor network, a garage door opener, or a home automation hub, the e07-m1101d’s flexible pinout and CC1101’s powerful features make it an excellent choice. Always refer back to this guide when wiring your module, and don’t forget to check Ebyte’s official datasheet for register-level details.
Here is a minimal code snippet for initializing the CC1101 using the SmartRC-CC1101-Driver-Lib on an ESP32: e07-m1101d pinout

is a highly reliable, low-power based on the industry-standard Texas Instruments CC1101 chip . Widely favored by hardware developers for IoT applications, home automation, and smart metering, this industrial-grade module offers stable short-range communication up to 1 kilometre under ideal conditions.
For low-power IoT devices, GD0 is invaluable. Instead of constantly polling the SPI bus to check for incoming data—which wastes energy—the microcontroller can enter a deep sleep mode and wake up only when GD0 asserts a hardware interrupt. This single pin transforms the module from a power-hungry peripheral into a truly event-driven, battery-friendly component. The secondary GD2 pin offers similar flexibility, often used to output a clock signal or a test signal for debugging.
The module features 8 pins organized in a 2x4 layout. The layout cleanly separates power supply connections from the standard 4-wire Serial Peripheral Interface (SPI) and generic digital I/O lines. New V2.0 E07-M1101D-SMA CC1101 · Issue #104 - GitHub
