E07-M1101D is a small-size wireless transceiver module developed by based on the Texas Instruments CC1101
When working with the E07-M1101D, it's essential to follow some tips and precautions: e07-m1101d pinout
Auto-reset for microcontroller programming Connecting 5V directly to the data pins can
Operating Frequency: 387MHz to 464MHz (Standard 433MHz band) Transmission Power: Max 10mW (+10dBm), software-adjustable e07-m1101d pinout
Ensure your microcontroller uses 3.3V logic. If using a 5V Arduino, you must use a level shifter for the input pins (CSN, SCK, MOSI) to avoid damaging the CC1101 chip.
If you are using an Arduino Uno or Mega, you must use a level shifter on the SPI lines (CSN, SCK, MOSI) or a voltage divider to drop the 5V signals to 3.3V. Connecting 5V directly to the data pins can permanently damage the CC1101 chip. Essential Tips for Success
