nRF52840
The MN52H high-end series, powered by Nordic Semiconductor's nRF52840 chip, offers a powerful module solution. It provides developers with greater design flexibility than the 52832 series and an outstanding 8dBm RF signaling capability. The complete multi-protocol embedded wireless microprocessor product combines low power consumption with high flexibility for developers to maximize their design concepts, product applications and mass production.
nRF52840 chip, built-in Contex M4 + FPU microsystem, and configured with 1MB of non-volatile memory and 256KB of random-access memory, providing users with more design and code storage space, which is conducive to enabling the production of more design and flexible applications. 48 GPIO versatility can be set via software, supports NFC-A tag for access control and quick configuration applications, full-speed USB 14Mbps input/output, 1.7V to 5.5V voltage input. Supports low power Bluetooth, Bluetooth Mesh, Thread, Zigbee, 802.15.4, ANT, and 2.4 GHz proprietary protocol overlays.
