E73-2G4M08S1EX are wireless Bluetooth modules that feature small size, and low power consumption. It adopts the originally imported RFIC nRF52833 of NORDIC, supporting
Bluetooth 5.1, Bluetooth mesh, 802.15.4, Thread, Zigbee, and proprietary 2.4 GHz protocols. The chip comes with a high-performance ARM CORTEX-M4 core, making use of a 32M industrial-grade crystal oscillator, and has abundant peripheral resources such as UART, I2C, SPI, ADC, DMA, and PWM. The module led out most IO Port of nRF52833 for multilateral development. Please see the pin definition for details.
E73-2G4M08S1EX is a hardware platform without firmware, so users
need to conduct a secondary development. The characteristics of the nRF52833 chip can be found in the official Datasheet. The module has maximized the RF characteristics of the chip。

E73-2G4M08S1EX is embedded with ARM MCU.
other serial port or JTAG、ISP、 ICP are unavailable to download.
2.The burn firmware needs to be completed in two parts. Since the protocol stack provided by NORDIC is not
loaded in the program, in the second development, you need to use the official burning tool nRFgo studio to burn
the protocol stack, and then use nRFgo studio to bum the hex of the application code; you can also use the official
burning tool nRF go studio to burn the protocol stack, and then download it with IAR or KEIL.
Application
Smart homes and industrial sensors;
Security system, positioning system;
Wireless remote control, drone;
Wireless game remote control;
Health care products;
Automotive industry applications.
