Ezurio’s latest edition to their Nordic Semiconductor based Bluetooth LE portfolio, is the most advanced, secure, and highest performing dual core MCU architecture wireless solution available. 

Based on the Nordic nRF5340 system-on-chip (SoC) and nRF21540 Front End Module (FEM), the BL5340PA series directly targets OEM customers requiring the longest range and highest MCU performance for their products’ wireless connectivity needs. Adding the nRF21540 RF FEM improves the link budget and connection robustness and significantly increases wireless range versus only using the nRF5340 SoC. The partnering of the nRF5340 and nRF21540 together into a certified module enables a wide range of use cases including industrial predictive maintenance and long range LE Audio capabilities. 

The dual core Arm® Cortex M33 microcontrollers enable you to run a low power core focused purely on wireless connectivity, with a second higher performance core targeted for the end application itself. This further extends the multi-protocol capabilities of the product: Bluetooth LE, 802.15.4 (Thread/Zigbee) and NFC. It’s further enhanced with an ARM CryptoCell-312 including trusted execution, root-of-trust, and secure key storage security features. 

The BL5340PA series brings out the nRF5340 & nRF21540 hardware features and capabilities including USB access, up to +18.5 dBm transmit power and a true industrial operating range of -40 to 105°C. Multiple regulatory certifications for both Bluetooth and 802.15.4 enables faster time to market and reduced development risk completes Ezurio’s simplification of your next multi-protocol wireless design!

BL5340PA - An easy-to-use module combining the power of the nRF5340 SoC with the range of the nRF21540 RF FEM

Watch our partner webinar with Nordic Semiconductor, where we give an introduction to the BL5340PA module, which seamlessly integrates the advanced nRF5340 SoC with the nRF21540 RF front-end module (FEM). Adding the nRF21540 RF FEM improves the link budget, connection robustness and significantly increases wireless range versus just using the nRF5340 SoC. These improvements are useful in various use cases, e.g, industrial and smart homes. All of this is in a small and certified module range with various integrated and external antenna options.

Does Ezurio provide breakout boards for its Bluetooth modules?

Is the nRF Connect SDK Used for developing applications on the BL5340PA?

When using an external 32.768KHz crystal I am unable to meet the 200mV to 1000mV peak to peak amplitude spec in the data sheet. Will this be a problem?

Can I use your FEM driver for BL5340PA to change gain value on the nrf21540?

Can I lower the TX Power on the BL5340 from the maximum set by the FW?

How can I get the maximum transmit (TX) gain for a specific region using the BL5340PA?

Does the BL5340, BL5340PA, BL65x and Lyra BLE modules include the DC-DC LC filters on the module?

What firmware do the BL5340/BL5340PA modules ship with initially? Can they initially be programmed via UART or FOTA or is it necessary to implement the SWD Interface?

Does the BL654PA or BL5340PA have EU Regulatory certifications (CE/EN)?

How can I change the 32.768KHz Low Power Clock Source using nRF Connect SDK v2.x?

Using STTY with the USB-SWD

Do the NFC traces need to be controlled differential impedance between NFC1 and NFC2?

How many LE Audio channels could be transferred on the BL5340 module at the same time?

Can more BL5340 modules work in parallel for channel expansion?
