This guide applies to the e07-m1101d as sold by EByte and compatible manufacturers. Always confirm with your batch’s datasheet.
The E07-M1101D is available in two primary DIP (Dual In-line Package) variants: the (equipped with an SMA-K connector for external antennas) and the E07-M1101D-TH (which features an onboard spring antenna). With a maximum transmission power of 10 mW (10 dBm), the module strikes an excellent balance between power consumption and communication range, which can reach up to 1 kilometer in open areas for the SMA version.

Connect to 3.3V and GND. Important: The module operates at 3.3V. Connecting to 5V will destroy the device.
If you want, I can:
Configurable I/O pins for status, with GDO0 often used for interrupts. Application Example: Arduino Mega
VCC (Pin 2) -> 3.3V GND (Pin 1) -> GND RXD (Pin 3) -> TX (Pin 2 on SoftwareSerial, or D1 on Uno) TXD (Pin 4) -> RX (Pin 3 on SoftwareSerial, or D0 on Uno) AUX (Pin 5) -> Digital Pin 4 (optional) M0 (Pin 6) -> Digital Pin 5 (or GND for default) M1 (Pin 7) -> Digital Pin 6 (or GND) RST (Pin 8) -> Digital Pin 7 (or 3.3V via 10kΩ) This guide applies to the e07-m1101d as sold
I will follow the search plan as outlined. The first step is to conduct the basic searches to gather initial information. search results have provided some initial information. I need to open several of these results to gather more detailed pinout and specification data. I will also perform a second round of deeper searches for application examples, coding libraries, and Chinese-language resources. information gathered so far includes pinout details from various sources, technical specifications from datasheets and product pages, and application examples. I also have some programming and hardware design guidance. Now I need to conduct the second round of searches as outlined in the plan. This includes searching for application examples, coding libraries, and Chinese-language resources. second round of searches has provided additional resources. I will open some of these results to gather more specific information for the article. have gathered a substantial amount of information. Now I need to structure the article. I will include sections like introduction, pinout description, technical specifications, interfacing with popular microcontrollers (ESP32, Arduino Uno, Arduino Mega, etc.), programming libraries, hardware design considerations, applications, troubleshooting, and a conclusion. I will cite the sources appropriately. The user wants a long article, so I will aim for depth and detail. Now I will write the article. is a comprehensive guide to the wireless module, covering everything from its pinout and technical specifications to interfacing with microcontrollers like the ESP32 and Arduino.
Here is a more detailed analysis of each pin's role and how to connect it correctly. With a maximum transmission power of 10 mW
Understanding the precise electrical mapping and wiring constraints of the 8-pin connector is critical to establishing a stable data link and preventing hardware degradation. E07-M1101D Pinout Assignment
