Demystifying the E07-M1101D Pinout: A Guide for Makers If you’ve recently picked up an Ebyte E07-M1101D wireless module for your latest IoT project, you might have noticed something confusing: the pinout doesn't always match the generic TI CC1101 diagrams you find online.
The E07-M1101D is a popular, low-cost transceiver based on the Texas Instruments CC1101 chip. While it's highly stable and great for smart home or industrial applications, "Version 2.0" of these modules often shifts from a 2x5 pin layout to a 2x4 pin layout, leaving many makers scratching their heads.
Here is everything you need to know to get wired up correctly. Understanding the E07-M1101D (V2.0) Pinout
Unlike standard CC1101 modules that often have 10 pins, the E07-M1101D typically utilizes an 8-pin (2x4) configuration. The core difference is the removal of redundant VCC and GND pins found on larger boards. Pin Mapping Table
When looking at the module from the front side (the side with the components and the "Ebyte" logo), the pins are typically numbered as follows: Pin Number Description 1 VCC Supply voltage (1.8V – 3.6V). Do not use 5V. 2 GND Common ground. 3 GD00 Digital I/O General purpose I/O pin (often used for data/sync). 4 CSN Chip Select (Active Low). 5 SCK Serial Clock input. 6 MOSI SPI Data In Master Out Slave In. 7 MISO SPI Data Out Master In Slave Out (GD01). 8 GD02 Digital I/O General purpose I/O pin (often used for interrupts).
Pro Tip: 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
Because this module operates at 3.3V, you must be careful when connecting it to 5V microcontrollers like the Arduino Uno. 1. ESP8266 / NodeMCU Connection
The ESP8266 is a natural fit for this module because it also operates at 3.3V. You can follow this common wiring scheme according to community guides on WordPress: VCC → 3V3 GND → GND CSN → D8 (GPIO15) SCK → D5 (GPIO14) MOSI → D7 (GPIO13) MISO → D6 (GPIO12) 2. Arduino (5V Boards)
If you are using an Arduino Uno or Mega, you must use a level shifter on the SPI lines (CSN, SCK, MOSI) or a voltage divider to drop the 5V signals to 3.3V. Connecting 5V directly to the data pins can permanently damage the CC1101 chip. Essential Tips for Success
Power Stability: The CC1101 can be sensitive to power noise. If you experience intermittent connection issues, solder a small 10µF capacitor across the VCC and GND pins of the module.
Antenna Choice: Whether you use a spring antenna or an SMA "duck" antenna, ensure it is firmly attached before powering on. Operating a radio module without an antenna can sometimes damage the output stage.
Library Compatibility: Most users recommend the SmartRC-CC1101-Driver-Lib on GitHub. It is highly optimized for these Ebyte modules and handles the nuances of the CC1101 registers better than generic SPI libraries. Wrapping Up
The E07-M1101D is a powerhouse for sub-GHz communication, but its compact 8-pin layout can be a "gotcha" for those used to standard TI reference designs. Once you have the pins mapped out, it’s one of the most reliable and long-range modules in its class. Ready to start your first transmission?

The schematic was coffee-stained, photocopied three times, and taped back together with scotch tape that had yellowed since the Clinton administration. It was the only documentation left for the "Project: Oracle" rig, a piece of Cold War surplus that the university physics department refused to throw away because "it still hums."
Elara blew a layer of dust off the chassis. The component in question sat in the center of the board like a black, eight-legged beetle: the E07-M1101D.
According to the manifest pinned to the wall, this was the "Geiger-Muller Interface Module." But the manifest was vague, and Elara needed to wire a modern data logger to the thing before the grant review on Friday.
She sat on the cold concrete floor of the basement lab, a battered multimeter in one hand and a notepad in the other. The internet was useless—searches for "E07-M1101D pinout" returned nothing but broken links to defunct Russian tech forums and a eBay listing for a "mystery lot of vintage capacitors."
"Okay," she muttered. "We do this the hard way."
Pin 1. She probed the first leg. The multimeter whined. Continuity to the ground plane. "Classic. Earth ground."
Pin 2. She traced the trace (no pun intended) back to a massive transformer. "High voltage input. Don't touch that."
Pin 3 and 4. Jumped together. They ran to a relay. "Trigger latching. Easy enough." Power Supply Pins : Pins 1, 3, 5,
She was feeling confident. The pattern seemed standard for 1970s-era hardware. She stripped the wires for her data logger, ready to tap into the output signal. She assumed Pin 6 would be the data out—six was usually the lucky number in these octal packages.
She lined up the probe. She touched it to Pin 6.
The machine didn't hum. It screamed.
A high-pitched oscillation tore through the silent basement. The needle on the ancient analog display on the front of the rig slammed past the red zone, vibrating violently against the stopper. The overhead fluorescent lights flickered in sympathy.
Elara yanked the probe away. The oscillation died down to a mournful whine, then silence.
Her heart hammered against her ribs. She looked back at the messy schematic. The tape was obscuring the diagram for that specific section. She peeled it back gently.
There, in fading blueprint ink, was a warning triangle. Next to Pin 6, it didn't say "Data Out." It said: "X-Ray Calibration Override."
She hadn't found the output signal. She had found the "cook everything in the room" button.
Elara stared at the chip. The E07-M1101D wasn't a standard interface. It was a safety interlock bypass used for maintenance—maintenance that was supposed to be performed with the lead shield down.
She took a deep breath, wiped the sweat from her forehead, and moved her probe to Pin 7.
"Please be data," she whispered. "Please be data."
She touched the pin. The multimeter beeped a steady, rhythmic pulse—one beep per second. The heartbeat of a radioactive isotope, safely measured and digitized.
She scribbled furiously on her notepad, updating the lost documentation for the next poor soul who might inherit this beast.
The E07-M1101D pinout was no longer a mystery. It was a warning.

Based on the part number format, the E07-M1101D is a wireless module manufactured by EBYTE (Chengdu Ebyte Electronic Technology). It is part of their long-range wireless series (likely based on the Si4463 or CC1101 RF chip, depending on the specific generation, though the 'M' often denotes high power).
Below is the standard pinout configuration for the E07-M1101D module.
Symptom: Unstable transmission, reduced range, or occasional resets when turning on a motor nearby.
Fix: Add a 10 µF tantalum or ceramic capacitor + 100 nF ceramic directly across VCC and GND.
Symptom: Module gets hot, no communication, eventual failure.
Fix: Use a level shifter or select a 3.3V MCU.
No. It is strictly sub-1 GHz (315–915 MHz). For 2.4 GHz, see ebyte’s E07-2G4M13S.
| Pin Number | Pin Name | I/O | Description | Notes | | :--- | :--- | :--- | :--- | :--- | | 1 | VCC | Power | Power Supply Input | Connect to 3.3V. Do not exceed 3.6V. | | 2 | GND | Power | Ground | Connect to system ground. | | 3 | ANT | I/O | Antenna Interface | Connect to a 50Ω antenna. Do not leave floating. | | 4 | GND | Power | Ground | Connect to system ground. | | 5 | TXD | Output | UART Transmit | Connect to MCU RXD. | | 6 | RXD | Input | UART Receive | Connect to MCU TXD. |
(Note: On some versions of EBYTE modules, Pins 5 and 6 might be labeled as DATA/CLK or DI/DO if they operate in SPI mode. However, the "D" in M1101D usually signifies a built-in MCU for UART serial transmission, making TXD/RXD the correct interface for standard usage.)
GD0 and GD2 PinsPerhaps the most elegant aspect of the pinout is the inclusion of GD0 (General Purpose Digital Output 0) and GD2 . These are not simple I/O pins; they are configurable interrupt lines. Depending on how you program the CC1101’s registers, GD0 can indicate various events: a packet has been received, a preamble has been detected, a transmission is complete, or the receive buffer is full.
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.
Symptom: Module resets randomly or never initializes.
Fix: Pull RESET to VCC with a 10k resistor (do not short directly to VCC unless your MCU GPIO can drive it low reliably).
Symptom: SPI reads return 0xFF or 0x00.
Fix: Double-check wiring – SI (pin 3) goes to MCU MOSI, SO (pin 5) to MCU MISO.
These determine the operating mode (e.g., normal, wake-up, power-saving, or configuration mode). Common mode table:
| M1 | M0 | Mode | Description | |----|----|-----------------|----------------------------------| | 0 | 0 | Mode 0 (Normal) | Wireless UART (transparent) | | 0 | 1 | Mode 1 (Wake-up) | Address wake-up transmission | | 1 | 0 | Mode 2 (Power-saving) | Low power listening | | 1 | 1 | Mode 3 (Config) | Enter AT command setup | Applications and Use Cases The E07-M1101D pinout has
