General Description

Ready for Bluetooth 5 and high grade IoT security

The SKB501 is an advanced, highly flexible single chip solution for today’s increasingly demanding ULP

wireless applications for connected devices on our person, connected living environments and the IoT at

large. It is designed ready for the major feature advancements of Bluetooth® 5 and takes advantage of

Bluetooth 5’s increased performance capabilities which include long range and high throughput modes.

Inherent industry-grade security is essential in today’s applications.

Bluetooth 5 – Bluetooth low energy further and faster

The nRF52840 is ready to take advantage of the considerable performance improvements for Bluetooth

low energy with the arrival of the Bluetooth 5 specification. Of greatest importance is the support for longer

range (up to x4 compared to Bluetooth 4.x) and doubling of on-air data-rate, up to 2Mbs from 1Mbs in

Bluetooth 4.x

Wide protocol support with addition of 802.15.4

The 802.15.4 PHY and MAC layers are supported natively on the nRF52840. This allows nRF52840 to be

used in a wide range of home and industrial sensor network applications as it supports two of the most

popular wireless sensor standards in use today, Bluetooth low energy and 802.15.4 derivatives. This adds to

the already existing radio support for Bluetooth low energy.

Bluetooth Module SKB501- User Manual Skylab M&C Technology Co., Ltd Application Block Diagram SKB501 Block Diagram Interfaces Power Supply Regulated power for the SKB501 is required. The input voltage Vcc range should be 1.7V to 3.6V. Suitable decoupling must be provided by external decoupling circuitry (10uF and 0.1uF). It can reduce the noise from power supply and increase power stability.
