Supports OOK, ASK, GFSK, 2-FSK, 4-FSK, and MSK
Understanding its pinout is critical for correct integration, as incorrect wiring can damage the module or degrade RF performance. e07-m1101d pinout
(Active Low). Initiates SPI communication when pulled low by the MCU. 5 SCK Supports OOK, ASK, GFSK, 2-FSK, 4-FSK, and MSK
The power group consists of VCC (3.3V) and GND . Notably, the module features three ground pins ( GND , GND , and the RF ground adjacent to the antenna). This redundancy is intentional; it minimizes ground loops and provides a clean, low-impedance return path for the high-frequency RF section, separating it from the digital noise of the logic section. This separation is a hallmark of professional RF design. 5 SCK The power group consists of VCC (3
If you are using an Arduino Uno or Mega, you 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
