E07-m1101d Pinout ((free)) -

// Set frequency to 433 MHz ELECHOUSE_cc1101.setMHZ(433);

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

Most users recommend the SmartRC-CC1101-Driver-Lib on GitHub. It is highly optimized for these Ebyte modules and handles the nuances of the CC1101 registers better than generic SPI libraries. Wrapping Up

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. e07-m1101d pinout

Understanding its pin configuration, electrical constraints, and host microcontroller wiring is critical to preventing damage and ensuring reliable long-range data transmission. E07-M1101D Complete Pinout Breakdown E07-M1101D Module, - Networking, Protocols, and Devices

: Module resets randomly or never initializes. Fix : Pull RESET to VCC with a 10k resistor (do not short directly to VCC unless your MCU GPIO can drive it low reliably). // Set frequency to 433 MHz ELECHOUSE_cc1101

"Please be data," she whispered. "Please be data."

If unused, leave them floating or pull down with a 10k resistor.

If you want, I can:

Jumped together. They ran to a relay. "Trigger latching. Easy enough."

. Connecting to a 5V source without level shifters will likely destroy the CC1101 chip. Antenna Importance:

Yes. But remember to use a level shifter if using a 5V Arduino (Uno, Mega). Most users recommend the SmartRC-CC1101-Driver-Lib on GitHub

: Connect to the hardware SPI Clock (D13 on Arduino Uno).
