Operates in the 433MHz ISM band (range: 300–348 MHz, 387–464MHz, and 779–928MHz). Transmission Power:
I have written this based on the standard (an 868/915 MHz SMD wireless module from Chengdu Ebyte). Note: If you meant a different variant (e.g., E07-M1101D-TH), the pinout may differ slightly.
: A common mistake is to route power through a 5V pin and GDO0 connections incorrectly. Always verify the pinout orientation. The pin numbering is often based on the component side of the board. If your wiring appears mirrored, you are likely looking at the underside (solder side).
The E07-M1101D is a versatile module that can be used in a wide range of applications, including: e07-m1101d pinout
The module typically features an 8-pin DIP header.

The E07-M1101D pinout has been a topic of interest and discussion among electronics enthusiasts, engineers, and hobbyists for quite some time. As a crucial component in various electronic systems, understanding its pinout is essential for designing, building, and troubleshooting circuits. In this in-depth review, we'll explore the E07-M1101D pinout, its applications, and provide valuable insights for those seeking to harness its potential.
The e07-m1101d is often confused with the E07-M1101D-S (with an integrated antenna). Regardless of the variant, the control pinout remains identical.
For many libraries, if you are not using advanced packet features, you may only need to connect GDO0, while GDO2 can be left floating, though mapping it is recommended for full functionality. : A common mistake is to route power
Understanding the precise is critical to avoid damaging its sensitive RF hardware and ensuring reliable Serial Peripheral Interface (SPI) communication with microcontrollers like Arduino, ESP8266, or ESP32. E07-M1101D Pinout Assignment
Approx. 16 × 24 mm Antenna: 50 Ω impedance, matched to a quarter-wave whip or a 470 MHz PCB trace antenna.
Always ensure you have a suitable 433MHz antenna connected to the SMA or spring terminal before powering the module to prevent damage to the RF power amplifier.
While strictly not a "pin" in the header sense, the dedicated pad and its adjacent ground must be discussed. The E07-M1101D typically features a stamped hole or a small pad for soldering a helical spring antenna or a u.FL connector. This RF pin has a 50-ohm characteristic impedance. Connecting this incorrectly—using a long, untwisted wire or a sloppy solder joint—will destroy the module’s range and could even damage the internal power amplifier due to reflected power (high VSWR). The dedicated ground pin next to the antenna is not optional; it provides the RF return path and must be connected directly to the system’s ground plane.
