Whether you use a spring antenna or an SMA "duck" antenna, ensure it is firmly attached before powering on. Operating a radio module without an antenna can sometimes damage the output stage.
: Connect to the hardware SPI Clock (D13 on Arduino Uno). e07-m1101d pinout
Because this module operates at , you must be careful when connecting it to 5V microcontrollers like the Arduino Uno. 1. ESP8266 / NodeMCU Connection Whether you use a spring antenna or an
She was feeling confident. The pattern seemed standard for 1970s-era hardware. She stripped the wires for her data logger, ready to tap into the output signal. She assumed Pin 6 would be the data out—six was usually the lucky number in these octal packages. Because this module operates at , you must
The CC1101 is controlled entirely via SPI. Ensure your microcontroller operates at 3.3V logic. If using a 5V MCU, use a (e.g., a voltage divider or dedicated IC).
When connecting the E07-M1101D to a microcontroller like an Arduino or ESP32, keep the following best practices in mind:
with a 2.54mm pitch. Unlike the larger 10-pin "v1" modules, this version is more compact but retains standard SPI connectivity. E07-M1101D Pinout Reference Looking at the module from the front side
