Improved Bluetooth with V4.2 and a New Variant with Enhanced 802.11ac/a/b/g/n Certified Dual-Band Wi-Fi Module

We are pleased to announce two significant upgrades to our popular VAR-SOM-MX7 System on Module product line: First, the upgrade from Bluetooth 4.1 to 4.2. Second, the launch of the VAR-SOM-MX7-5G variant with an improved Certified Wi-Fi module.
The upgrade to Bluetooth/BLE 4.2 applies to the entire VAR-SOM-MX7 product-line and brings significant improvements in terms of higher speed and security. This innovated technology has a direct and significant impact on IoT devices, especially those with a critical requirement for privacy.
The VAR-SOM-MX7-5G variant is enhanced with the newest generation of Wi-Fi standard, supporting 802.11ac/a/b/g/n and dual-band 2.4/5 GHz. The variant is fully certified, provides effective bit-rate and improved performance, an ideal platform for devices requiring simultaneous connections or high data transfer rates over the wireless network.
