E07-m1101d Pinout Repack Jun 2026
The E07-M1101D is a versatile module that can be used in a wide range of applications, including:
The ESP32 is an ideal partner for this module because it works at 3.3V logic. The following pin mapping is known to work perfectly with the ESPSomfy-RTS and RadioLib libraries:
E07-M1101D is a 433MHz wireless transceiver module based on the Texas Instruments CC1101 chip. It typically features a 2x4 (8-pin) DIP header Pinout Configuration (8-Pin Layout)
1.8V to 3.6V (Do not exceed 3.6V to avoid damage). Frequency Range: 433MHz (tunable via software). Modulation: Supports 2-FSK, GFSK, MSK, and OOK/ASK. Transmission Power: Maximum 10mW (+10dBm). Communication Interface: Standard 4-wire SPI. Usage and Integration e07-m1101d pinout

Elara yanked the probe away. The oscillation died down to a mournful whine, then silence.
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.
