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.
The is a popular compact UART serial transceiver module based on the CC1101 RF chip, operating in the 868/915 MHz ISM band. Understanding its pinout is critical for proper integration into your project. e07-m1101d pinout
Here is a detailed breakdown of the E07-M1101D pinout: Note: Pins 1–10 are the 1
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. Understanding its pinout is critical for proper integration
