| Pin Number | Pin Name | Type | Description | |------------|----------|------------|-----------------------------------------------------------------------------| | 1 | GND | Power | Ground (0V). Must be connected to system ground. | | 2 | VCC | Power | Positive supply voltage (1.8V – 3.6V, typical 3.3V). | | 3 | SI (MOSI)| Digital In | SPI data input. Connect to master’s MOSI pin. | | 4 | SCK | Digital In | SPI clock input (up to 10 MHz). Connect to master’s SCK. | | 5 | SO (MISO)| Digital Out| SPI data output (tri-state when CSn high). Connect to master’s MISO. | | 6 | CSn (SS) | Digital In | SPI chip select (active low). Must be toggled for each transaction. | | 7 | GDO2 | Digital I/O| General purpose digital I/O (configurable – often used for RX/TX status). | | 8 | GDO0 | Digital I/O| General purpose digital I/O (can output clock or RSSI). | | 9 | RESET | Digital In | Active low reset input. Pull high to VCC for normal operation. | | 10 | GND | Power | Second ground pad. Usually internally connected to pin 1. |

Here are proven wiring examples for popular development boards. e07-m1101d pinout

Ensure your microcontroller uses 3.3V logic. If using a 5V Arduino, you must use a level shifter for the input pins (CSN, SCK, MOSI) to avoid damaging the CC1101 chip.

Once the hardware is wired, you need to load software onto your microcontroller to control the module. | Pin Number | Pin Name | Type

The library is highly recommended for its extensive features and ease of use. It supports the CC1101 and many other radio modules. A basic setup in an Arduino sketch might look like this:

| Pin | Name | Direction | Description | |-----|----------|-----------|-----------------------------------------------| | 1 | GND | Power | Ground (0V) | | 2 | VCC | Power | Power supply (1.8V – 3.6V DC) | | 3 | RXD | Input | UART Receive (Connect to TX of host MCU) | | 4 | TXD | Output | UART Transmit (Connect to RX of host MCU) | | 5 | AUX | Output | Indicator pin (Low = busy, High = ready/idle) | | 6 | M0 | Input | Mode setting pin 0 (Internal pull-down) | | 7 | M1 | Input | Mode setting pin 1 (Internal pull-down) | | 8 | RST | Input | Reset (Active low; pull high for normal run) | | 9 | NC | – | No connection (leave floating) | | 10 | GND | Power | Ground (0V) | | 11 | ANT | RF | Antenna (50Ω, usually via a hole/pad) | | 12 | GND | Power | Ground (0V) |

The E07-M1101D must have an antenna attached to the SMA connector or spring solder point for stable communication. Operating without an antenna can degrade performance or damage the component.

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.

The E07-M1101D is controlled entirely through the SPI bus, a standard synchronous serial communication interface.
