E07-m1101d Pinout

To reduce ground inductance and improve RF performance. Always connect both if possible.

Before examining the pinout, let’s briefly review the module’s key specifications: e07-m1101d pinout

A decoupling capacitor (e.g., 10µF to 100µF) placed close to the VCC and GND pins is highly recommended to handle current spikes during transmission. E07-M1101D-TH User Manual - Ebyte To reduce ground inductance and improve RF performance

| Module Pin | Connect to MCU | Note | |------------|----------------------------------------|-----------------------------| | 3.3V | 3.3 V output (LDO) | Max 3.6 V, never 5 V | | GND (2) | GND | Common ground | | RST (4) | GPIO | Optional – pull-up resistor| | SCK (5) | SPI SCK | | | MISO (6) | SPI MISO | | | MOSI (7) | SPI MOSI | | | NSS (8) | SPI CS (GPIO) | Active low | | BUSY (9) | GPIO (input, interrupt capable) | Mandatory | | DIO0 (10) | GPIO with interrupt | Optional but recommended | | DIO1 (11) | GPIO (or leave NC) | Optional | | NC (12) | No connect (or GND if specified) | | E07-M1101D-TH User Manual - Ebyte | Module Pin

387MHz to 464MHz (Standard 433MHz band) Transmission Power: Max 10mW (+10dBm), software-adjustable

. Connecting to a 5V source without level shifters will likely destroy the CC1101 chip. Antenna Importance:
