E07-m1101d Pinout
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.
Introduction In the world of embedded systems and wireless communication, the e07-m1101d stands out as a highly efficient, low-power RF module. Developed by Chengdu Ebyte Technology, this module is based on the Texas Instruments CC1101 transceiver IC. It operates in the sub-1GHz frequency bands (315/433/868/915 MHz), making it ideal for smart home devices, industrial sensors, remote controls, and IoT gateways. e07-m1101d pinout

Q1: What is the difference between e07-m1101d and CC1101? The e07-m1101d is a breakout module containing the CC1101 chip, crystal, matching network, and antenna connector. The pinout refers to the module’s pads, not the IC’s bare pins. Q2: Can I use this module with Arduino’s SPI library? Yes. But remember to use a level shifter if using a 5V Arduino (Uno, Mega). Q3: Why are there two GND pins? To reduce ground inductance and improve RF performance. Always connect both if possible. Q4: Does the e07-m1101d support 2.4 GHz? No. It is strictly sub-1 GHz (315–915 MHz). For 2.4 GHz, see ebyte’s E07-2G4M13S. Q5: What is the maximum SPI clock speed? 10 MHz, but 1–4 MHz is more reliable for long wires. 9. Conclusion Mastering the e07-m1101d pinout is the first and most critical step toward building a robust wireless system. By correctly connecting power, SPI lines, and configurable IO pins—and avoiding common pitfalls like 5V logic or a floating RESET—you ensure reliable communication, maximum range, and long module life.
