Telit’s WE310G4 module lets device vendors add dual-band wifi and Bluetooth Low Energy (BLE) 5.0 connectivity to their products.

Based on the Realtek Ameba system-on-chip (SoC), the module is suitable for embedded devices, including smart lighting, home appliances, medical wearables, smart city sensors, aftermarket telematics and industrial robots.

Suitable for vendors that have limited wifi or BLE expertise, as well as those with extensive RF experience that want to reduce time to market for new products, the module is IEEE 802.11 a/b/g/n and Bluetooth certified, and complies with all Wifi Alliance and Bluetooth SIG-v5 requirements, eliminating the time and expense of testing and certification.

It provides device vendors with a low-cost, high-speed serial-to-Wifi-and-BLE connection to an embedded design built on an 8, 16 or 32bit microcontroller. Further, the module can be implemented as a host-less option offering up to 456kbit of SRAM dedicated to user application development.

With marketing samples available this month, the module includes a package of features and capabilities:

  • Integrated, dual-core SoC, a high-performance application processor running on Arm Cortex-M33 and a low-power MCU Cortex-M23 for wifi and BLE.
  • Support for a wide range of peripherals: SDIO, SPI, uart, ADC, PWM, GPIO, I2S, I2C and USB.
  • Low power consumption to increase battery life.
  • Industrial grade temperature range of -40 to +85˚C.
  • Self-contained with full wifi, BLE and TCP IP networking stacks.
  • Suite of security features including secured boot, TrustZone for Cortex-M, WPA3 personal and enterprise security modes, as well as upper-layer security protocols such as TLS-1.3/SSL and HTTPS.
  • Serial-to-wifi hosted implementation.
  • Telit IoT AppZone IDE for host-less application development.
  • Pin-to-pin compatible with the Telit WE310F5 single-band module, enabling rapid migration of existing hardware and software to the WE310G4.
  • Available with (WE310G4-I) and without (WE310G4-P) antenna.

“Ultra-low power consumption, small size and high security are critical for modules integrating with the global IoT ecosystem,” said Yee-Wei Huang, Realtek vice president. “While the IoT market offers a wide range of small modules, none compares to Telit’s WE310G4 when it comes to quickly and cost-effectively adding dual-band wifi and Bluetooth connectivity into their customer products. Combined with Realtek Ameba SoC, the WE310G4 is perfect for home, medical and industrial IoT applications.”

Manish Watwani, chief product officer at Telit, added: “The new Telit WE310G4 module gives vendors a fast, easy way to add wifi or BLE to their products, even if they have little or no in-house RF expertise. It’s ideal for vendors that want to develop wearables, IoT sensors and other products with enterprise-grade security, long battery life and other market-differentiating features, and then have them in customers’ hands before competitors do.”

Engineering samples will be available in Q2, with mass production scheduled to begin in Q3 2022.
