IMM-NRF52840(BLYST840)数据手册i-SYST中文资料规格书

描述 Description

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.\r
\r
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\r
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.\r
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.
