E07-m1101d Pinout

The intelligence of the E07-M1101D is accessed via a standard 4-wire SPI (Serial Peripheral Interface) bus. This occupies four critical pins: SI (Master Out Slave In / MOSI), SO (Master In Slave Out / MISO), SCLK (Serial Clock), and CSN (Chip Select Not). Unlike simpler RF modules (like the 433MHz ask/ook modules), the CC1101 inside the E07-M1101D contains dozens of internal configuration registers. The SPI interface is the gateway to these registers, allowing the engineer to program frequency deviation, data rate, output power, and channel filtering.

Here is a detailed breakdown of the E07-M1101D pinout: e07-m1101d pinout

The CSN pin plays a particularly crucial role. It must be pulled low to initiate a communication session; otherwise, the module ignores the bus. This enables multiple SPI devices to share the same data lines. Without a proper understanding of CSN timing, the module will remain silent, leading to the classic "no response" debugging headache. The SPI interface is the gateway to these

Looking at the module from the (shielded can facing up), the pads are arranged as follows:
