E07-m1101d — Pinout ~repack~

: Some e07-m1101d modules have an 11th pin (labeled “GND”) at the bottom center for mechanical stability and improved grounding. Electrically, it is identical to pins 1 and 10.

The module is a reliable and well-supported 433 MHz wireless solution. Its core is the TI CC1101 chip and it communicates via a standard SPI interface. By accurately connecting the 8 pins—especially ensuring a clean 3.3V power supply and correct SPI wiring—you can integrate the module with a wide range of microcontrollers like the ESP32 and Arduino for projects in home automation, industrial control, and wireless sensing. With robust library support and thorough documentation, the E07-M1101D is a solid foundation for your next wireless project.

Before examining the pinout, let’s briefly review the module’s key specifications:

When designing or troubleshooting hardware circuits with this module, understanding the is critical. Older generic CC1101 breakout boards frequently feature a 10-pin layout, whereas the modern E07-M1101D utilizes a streamlined 8-pin Dual In-line Package (DIP) footprint. This article provides a comprehensive breakdown of the pin configurations, functional descriptions, wiring schematics, and critical deployment practices.

Here is a minimal code snippet for initializing the CC1101 using the SmartRC-CC1101-Driver-Lib on an ESP32:

| Symptom | Likely Cause | Fix | |-----------------------------|---------------------------------------|--------------------------------------| | No SPI response (MISO stuck)| NSS not pulled low; BUSY ignored | Assert NSS low; wait for BUSY=0 | | Module resets randomly | Insufficient 3.3V decoupling | Add 100 µF bulk cap near pin 3 | | No RF output | Antenna not connected / wrong pinout | Check pin 1 connection; add matching | | Erratic DIO0 interrupts | Floating interrupt line | Enable internal pull‑down or external 10 kΩ | | Overheating | 5 V applied to any pin (even briefly) | Replace module; use level shifter |
