Product Details
Multi-Protocol 2.4 GHz SoC Architecture
Built on the Silicon Labs EFR32 SoC, the E76-2G4M10S1A supports concurrent multi-protocol operation — including BLE 6.0, Zigbee, and Thread — within a single compact module. This eliminates the need for separate RF chips in mixed-protocol deployments, reducing BOM cost and PCB area.
Ultra-Low Power Design for Battery-Powered IoT
The EFR32 core features hardware-level energy management with multiple sleep modes. Sleep current reaches μA level, enabling years of operation on coin-cell or AA batteries — ideal for wireless sensors, asset trackers, and smart metering nodes.
Industrial-Grade RF Front-End & EMC Design
50 Ω impedance-matched RF front-end with integrated SAW filter and metal shielding. Spurious emissions suppressed to ≤ -60 dBc, compliant with ETSI EN 300 328 and FCC Part 15.247. Stable RF performance maintained across the full -40℃ to +85℃ operating range.
Ideal Applications
| Smart Home & Building | BLE mesh lighting control, door locks, occupancy sensors, HVAC automation |
| Industrial Wireless | Sensor telemetry, remote I/O, PLC wireless extension, condition monitoring |
| Medical & Wearables | BLE health monitors, glucose meters, fitness trackers |
| Smart Metering | Zigbee/Thread-based water, gas, and electricity meter data collection |
| Asset Tracking | BLE beacon-based indoor positioning and inventory management |
| IoT Gateways | Multi-protocol 2.4 GHz edge node connecting to cloud platforms |
FAQ
Q1: What wireless protocols does the E76-2G4M10S1A support?
A: The module supports Bluetooth LE 6.0, Zigbee 3.0, Thread, and proprietary 2.4 GHz protocols simultaneously, enabled by the Silicon Labs EFR32 multi-protocol SoC. Protocol switching or concurrent operation is managed via the Gecko SDK.
Q2: Is this module compatible with Apple Find My / Matter ecosystems?
A: The EFR32 platform supports Matter over Thread and BLE, making the E76-2G4M10S1A a suitable hardware base. Firmware integration with Apple Find My or Matter requires additional SDK configuration and Apple MFi certification by the end-product manufacturer.
Q3: How do I configure the module — AT commands or SDK?
A: UART-interface versions support AT command configuration and Ebyte's USB configuration tool. For advanced use, the EFR32 SoC can be programmed directly via Silicon Labs Simplicity Studio and the Gecko SDK, enabling custom BLE profiles, Zigbee clusters, or Thread device roles.
Q4: Does the module carry FCC and CE certifications?
A: Yes. The E76-2G4M10S1A holds FCC Part 15.247 and CE (RED) 2014/53/EU certifications, along with RoHS compliance. Modular FCC certification allows integration into end products with reduced re-certification requirements — consult Ebyte for grant details.
Q5: What is the maximum communication range?
A: In open-air line-of-sight conditions with BLE long-range (Coded PHY, SF=8), the E76-2G4M10S1A can achieve up to 300–500 m at 10 dBm TX power. Actual range depends on antenna gain, environment, and protocol PHY settings.
Q6: Can I connect this module to a Raspberry Pi or Arduino?
A: Yes. The UART interface is compatible with Raspberry Pi (3.3 V logic). For Arduino (5 V), add a 4–10 kΩ level-shifting resistor on TXD and AUX lines. Ebyte provides AT command documentation; sample code is available from the Silicon Labs Gecko SDK examples.
Q7: What is the free sample policy?
A: This listing offers 1 free sample unit at $0.10 (handling fee), limited to 2 pcs per person across all Ebyte sample models. Samples are dispatched within 2 business days via DHL/UPS/FedEx. Bulk pricing and OEM/ODM services are available — contact Ebyte sales for a quote.
