1 Product overview
1.1 Brief Introduction
E73-2G4M08S1E is a small-sized, low-power multi-protocol module developed by Ebyte. It adopts
the original imported nRF52833 radio frequency chip from Nordic, supports Bluetooth 5.1, Ble
mesh, Thread, Zigbee; This chip comes with a high-performance ARM CORTEX-M4 core , Adopts
32M industrial-grade crystal oscillator, and has abundant peripheral resources such as UART, I2C,
SPI, ADC, DMA, PWM, etc.; nRF52833 leads to most of the I/O ports, please check the pin
definitions for details, which is convenient for users to carry out multi-directional Development.
E73-2G4M08S1E is a hardware platform, and there is no program at the factory, and the user needs
to carry out secondary development; please refer to the official datasheet for the characteristics of the nRF52833 chip, and the module
has fully utilized the RF characteristics of the chip.
