Panasonic PAN1780 Bluetooth® Low Energy RF Module
Bluetooth Low Energy module supports mesh networking for smart lighting control.
The PAN1780 from Panasonic is an integrated Bluetooth® Low Energy wireless module which includes a microcontroller core and generous memory provision for running the host application as well as multiple radio protocols.
Offering Bluetooth mesh networking capability and connectivity to smartphones, the PAN1780 eliminates the need for a dedicated gateway to control lighting systems. This provides a simple implementation of smart lighting control and means that there is no risk of system malfunction caused by a single point of failure.
In addition, the PAN1780 provides the capability to perform software updates over-the-air, and has enough processing power to perform edge-computing functions.
Fully compliant with the standard Bluetooth 5.0 specifications, the PAN1780 also supports the IEEE 802.15.4 and NFC-A radio technologies. When used in other types of applications, the new advertising extensions in the Bluetooth Low Energy specification allow for much larger amounts of data to be broadcast in connectionless scenarios.
Featuring an Arm® Cortex®-M4F processor core, the PAN1780 provides 256kbytes of RAM and 1Mbyte of Flash memory. This means that it can easily be used in stand-alone mode, without an external processor. This reduces the complexity of the board design, saves space and reduces system cost.
Based on the Nordic nRF52840 single-chip radio controller, the PAN1780 offers a data-transfer rate of 2Mbits/s via its built-in high-speed radio transceiver. Sensitivity is -95dBm at 1Mbit/s and -103dBm at 125kbits/s. Output power is configurable up to a maximum of 8dBm.
The PAN1780’s surface-mount package measures 15.6mm x 8.7mm x 2.0mm. Its outline is the same as that of the Panasonic PAN1026A and PAN1762 radio modules.
Smart Lighting: A Versatile, Safe and Secure Way to Implement Lighting Control
Smart home devices such as the Amazon Echo or Google Home controllers are growing in popularity. These audio devices which connect to a smartphone are particularly common in North America and Europe.
Comfort and convenience are usually the main reasons for installing such smart home devices. But other factors can also play a role: intelligent door locks or smart meters can enhance the residents’ safety and control. For instance, by monitoring daily energy consumption, emissions and costs can be substantially reduced.
All these aspects – safety, comfort and control - apply particularly strongly to home lighting. Efficient and versatile LED lighting solutions are more than just a replacement for the classic light bulb. Since the power consumption of LED lighting devices is much lower and their lifetime is much higher than that of old-fashioned light bulbs, the benefits of LED lighting are obvious.
Now, analysts predict that close to one third of all households in Europe will be using smart home applications by the end of 2023. Applications for entertainment, heating and cooling as well as smart locks and smart lighting applications are expected to be the most popular.
The introduction of the Bluetooth 5.0 specification for Bluetooth Low Energy connectivity opens up a new set of applications. The new key features of Bluetooth 5.0 are a higher data rate and very low energy consumption, alongside the availability of Bluetooth mesh networking. In the PAN1780 Bluetooth Low Energy module, this is complemented by Zigbee and Thread, wireless technologies which are also used in lighting control applications.
Once connected, LED lighting installations have the potential to carry other control signals and sensor data. Because lighting is almost everywhere in every building, it is the perfect medium for sharing data on parameters such as temperature or humidity around a building.
