Introduction E73-2G4M04S1B is a SMD bluetooth wireless module based on NORDIC's nRF52832 RF chip. NRF52832 has high-performance ARM CORTEX-M4 core and Bluetooth 4.2 and Bluetooth 5 RF transceiver and protocol stack, and has abundant peripheral resources such as UART, I2C, SPI, ADC, DMA, PWM, etc.The module brings out almost all IO ports, which is convenient for users to conduct multi-faceted development, Please see pin definitions for details. The module has built-in PCB antenna and can connect other antennas through IPEX. The product has obtained FCC, CE, RoHS and other international authoritative certification reports, users do not need to worry about its performance. We use a 32MHz high precision low temperature drift active crystal to ensure its industrial properties and stability. Because this module is a pure hardware SoC module, users need to program it before they can use it.
Features Communication distance tested is up to 100m Maximum transmission power of 2.5mW, software multi-level adjustable Support bluetooth 4.2 and bluetooth 5.0 Built-in 32.768 kHz clock crystal oscillator Support for the global license-free ISM 2.4GHz band Rich resources, 512KB FLASH, 64KB RAM Support 2.0V~3.6V power supply, more than 3.3V power supply can guarantee the best performance Industrial grade standard design, support -40 ~ 85 °C for a long time Support onboard PCB antenna and IPEX interface, users can choose according to their needs
