Always verify your specific version! Some older Ebyte modules might still use a 10-pin header. If yours has 8 pins, it is almost certainly the V2.0 layout mentioned above. Wiring for Popular Microcontrollers

Note: Pins 1–10 are the 1.27mm pitch castellation pads along the module edges. Pin 11 (ANT) and Pin 12 (GND) are typically the two large pads near the antenna area. Always verify your specific version
(Note: Pin 1 is typically marked with a pad or near the antenna connection point on the PCB edge.) (Note: Pin 1 is typically marked with a
. Connecting to a 5V source without level shifters will likely destroy the CC1101 chip. Antenna Importance:
The module requires an external antenna (usually via an SMA connector or stamp hole). Performance varies significantly based on antenna quality and placement. Software Libraries: For Arduino users, libraries like the SmartRC-CC1101-Driver-Lib are widely recommended for easy integration.
