Bluetooth® 5, Zigbee, Thread Module

BLYST840 is built around the Nordic nRF52840 32-bit ARM® Cortex™-M4F CPU with floating point unit running at 64 MHz. It has protocol support for Bluetooth 5, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary stacks.

  • It is a fingertip size 14 x 9 x 1.5 mm SoM with all required components (crystals, coils, DC/DC, etc.) built-in and ready to use. So you don't need to take up more board space with add-on components needed to support a given module
  • It’s designed as a feature-rich but tiny and ultra-low-power SoM to make it easy to integrate into your own projects and IoT hardware.
  • BLYST840 has 46 I/O, 1 MB flash, 256 kB RAM, is ready for Bluetooth® 5.2, is Thread and ZigBee capable, is NFC-enabled, has built-in security measures, and supports MicroPython.
