The ESP8266 also operates at 3.3V, making it a great choice. According to tests on the NodeMCU board, the following connections work reliably:
This article serves as a complete reference for the , providing you with everything you need to start using this module effectively, from basic connections to advanced coding examples.
: Must be connected to 3.3V ; connecting to 5V will likely damage the module. CSN : Connect to a digital pin (often D10 on Arduino).
Before diving into the pinout, it helps to know what this module is. The is a "DIP" (Dual Inline Package) wireless module. It has a transmission power of up to 10dBm (10mW) and can achieve communication distances up to 600 meters under ideal conditions in open areas. Its core is the industrial-grade CC1101 chip from Texas Instruments, which supports a variety of modulation modes, including OOK, ASK, GFSK, 2-FSK, 4-FSK, and MSK. Its programmable data rate ranges from 0.6kbps to 500kbps.
:
1.8V to 3.6V (⚡ Do NOT use 5V directly; it will damage the module) Max Power: 10dBm (~10mW)
The E07-M1101D is a specific model of a microcontroller or a dedicated IC (Integrated Circuit) designed for a particular application. Unfortunately, the manufacturer and exact specifications of this component are not readily available, which has contributed to the mystique surrounding its pinout. However, through extensive research and analysis, we have compiled a comprehensive overview of its pin configuration and functionality.
