E73-2G4M04S1AX is a small volume chip Bluetooth wireless module independently developed based on nrf52810 chip of Nordic of Norway. It adopts 32mhz industrial crystal oscillator to ensure its industrial characteristics and stable performance. NRF52810 comes with high-performance arm cortex-m4 core, RF transceiver and protocol stack of BLE 4.2 and BLE 5.0, and it has rich peripheral resources such as UART, I2C, SPI, ADC, DMA, PWM, etc. The module leads out almost all IO ports. Please check the pin definition for details, so as to facilitate users to carry out multi-directional development. The module can be connected with other antennas through IPEX.
Because the module is a pure hardware SOC module, it can be used only after the user program sit.
Note: For more technical information, refer the datasheet in attachments.
