E07-m1101d Pinout May 2026

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.

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 e07-m1101d is a compact, low-power RF transceiver module based on the Semtech SX1276 LoRa® chipset. It operates in the 410–525 MHz frequency band (often configured for 433/470 MHz) and is designed for long-range, low-data-rate applications such as IoT sensors, smart metering, and remote controls.

Understanding its pinout is critical for correct integration, as incorrect wiring can damage the module or degrade RF performance.

The E07-M1101D 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.

In the rapidly evolving landscape of the Internet of Things (IoT) and embedded systems, the difference between a successful prototype and a failed project often hinges on the smallest details. Among these critical details is the pinout—the functional map of a module’s physical interface. The E07-M1101D, a compact and powerful 433MHz wireless transceiver module based on the CC1101 chipset, is a perfect case study. Understanding its pinout is not merely about connecting wires; it is about understanding the module’s operational philosophy, power management, and data flow. The E07-M1101D’s pin configuration is a masterclass in efficient design, balancing minimalism with functional necessity for long-range, low-power applications. e07-m1101d pinout

E07-M1101D is a compact 433MHz wireless transceiver module based on the Texas Instruments CC1101 chip, commonly used in smart home systems, industrial automation, and long-range DIY projects. Unlike many standard CC1101 modules that use 10 pins, the E07-M1101D series typically features an 8-pin DIP header Pinout and Hardware Connections

The module communicates via a 4-wire SPI interface and provides two universal digital output pins (GDO pins) for flexible functions like wake-on-radio or signal assessment.

chip. It typically features an 8-pin DIP (Dual In-line Package) layout designed for SPI communication with microcontrollers. E07-M1101D Pinout Definition

The module uses a standard 2x4 pin header with a 2.54mm pitch. The pins are defined as follows: Description Ground connection Power supply (1.8V – 3.6V DC) General Purpose Digital I/O pin 0 SPI Chip Select (Active Low) SPI Master Output Slave Input MISO / GDO1 SPI Master Input Slave Output / GDO1 General Purpose Digital I/O pin 2 Key Technical Specifications Operating Frequency: 387MHz to 464MHz (Default: 433MHz). Supply Voltage: 1.8V to 3.6V. Voltages above 3.6V will permanently damage the module. Communication Interface: 4-wire SPI (CSN, SCK, MOSI, MISO). Transmission Power: Maximum 10mW (10dBm), software-adjustable. Transmission Distance: Roughly 500m to 600m in open air. Modulation Modes: Supports OOK, ASK, GFSK, 2-FSK, 4-FSK, and MSK. Implementation Tips Logic Levels:

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.

The "SMA" version (E07-M1101D-SMA) includes an SMA connector for external antennas, which significantly improves range compared to the spring antenna version. Power Stability:

A decoupling capacitor (e.g., 10µF to 100µF) placed close to the VCC and GND pins is highly recommended to handle current spikes during transmission. E07-M1101D-TH User Manual - Ebyte
