Description
The E73-2G4M04S1BX from EByte is a professional-grade Bluetooth Low Energy module engineered for reliable bidirectional wireless communication. Built around Nordic Semiconductor Semiconductor’s proven nRF52832 system-on-chip, it combines a powerful 32-bit ARM Cortex-M4F processor with floating-point unit and ample memory resources to run custom firmware stacks like Zephyr RTOS, Nordic Semiconductor’s nRF5 SDK, or Arduino core libraries.
Operating in the global 2.4GHz ISM band (2379-2496MHz), the module supports both legacy BLE 4.2 and modern BLE 5.0 feature sets, including 2x PHY for higher data rates and improved coexistence. Its integrated +4dBm RF power amplifier and -95dBm receiver sensitivity, coupled with the external IPEX antenna interface, provide robust link budgets for applications requiring extended range or penetration through obstacles.
Designed for surface-mount assembly, the module’s compact 17.5 x 23.5mm footprint and 1.8-3.6V wide voltage input make it a versatile drop-in solution for product designers, enabling rapid integration of Bluetooth connectivity into wearables, sensor nodes, remote controls, and smart home devices without complex RF layout challenges.
