Bluetooth technology has been developing over decades, Nordic nRF5340 no doubt is the most important edge cutting wireless evolution released in 2020 since then. Throughout the common either audio or data Bluetooth transmission to advanced data & audio connection between devices, IoT applications now have already been derived from past simple purpose toward contemporary comprehensive and complex implements in either commercial or industrial fields.
MDBT53 is a System-on-Module (aka SoM) with a good size of 9.3mm x 14.3mm and 48 GPIO which is an ideal dimension to fit in most applications. MDBT53 provides 3 antenna options, Chip antenna; PCB antenna; and u.FL connector for external antenna which deliver a maximum feasibility for most IoT projects.
MDBT53V is designated for the application which has a space constraint design. A 7.8mm x 12.4mm with 25 GPIO is small enough to offer the opportunity of employing nRF5340 modules in the project. In addition, the module offers an extended working temperature of up to +105°C enabling the module to become the most reliable connectivity source for industrial applications. MDBT53V provides 2 options of antenna, Chip and PCB, for developers’ selection which is capable of optimizing the project plan in terms of performance and budgetary.
Over the past few years, Raytac experienced the fast changing of Bluetooth technology from BT2 all the way to latest BT5.2; from heavy power consumption to advanced Low Energy. Raytac is determined in its the mission to provide better module service in the aspects of quality, coverage, and stable pipeline to all partners. MDBT53 & MDBT53V, nRF5340 solution modules, an epochal Bluetooth technology which significantly improves the connectivity ability from data transmission toward audio broadcasting which would be the best model to provide technology that could benefit and contribute to people’s lives.
Raytac released MDBT50 series module which deployed Nordic latest nRF52 member, nRF52820 solution. nRF52820’s specification looks similar to nRF51822, but offer superior features than ever.
The nRF52820 features an Arm Cortex-M4 processor, 256 KB Flash and 32 KB RAM and offer I2C/SPI/UART but also full speed USB 2.0 interface which provide the maximum flexibility for commercial and industrial applications.
MDBT50 employed nRF52820 can be supplied with a voltage from 1.7 to 5.5 V, -40°C~105 industrial operation temperature. Features Upto +8 dBm output power and supports BT5.2 Direction Finding, high-throughput 2 Mbps, Long Range. Multiprotocol radio provides, Thread and Zigbee and Bluetooth mesh protocols.
MDBT50 series modules covers both nRF52833 and nRF52820 solutions and provide both chip and PCB antenna for customer’s selection. Developers are encouraged to visit Raytac website for more information.
To ensure the Module is capable to work under 105°C, Raytac’s conducted a 72 hrs non-stop connection reliability test. The significant result shows there is no any single packet lost over 252,979,200 bytes (244 bytes/Packet).
Raytac today introduces that Bangalore, India based partner and solution provider, Atoll Solutions Pvt Ltd., has released a BLE beacon feathers way-finding, tour-guide, environment sensing, motion sensing and asset tracking.
Atoll’s BLE beacon deploy Raytac’s MDBT42Q series of modules which employ Nordic nRF52X deliver the ideal platform to for building low-power & long-life BLE beacons. The beacons are available for B2B customers in a variety of form factors e.g. lanyard hook and tile. The beacons are built to be robust, and have been tested as a part of the Atoll Kinesis indoor location tracking platform.
“Raytac Bluetooth module provides an optimal and stable RF efficiency which easy the hardware design resource Atoll need. The compact size, stable quality and pre-certified modules also offer an advantage to speed up time to market efficiency and minimal the BOM cost.” says Jithu Niruthambath, Co-Founder & CEO at Atoll Solutions.
It figures, Raytac launched nRF52820 & nRF52805 modules soon after Nordic released the SoC. As usual, all modules by Raytac are Bluetooth qualified and regulation pre-certified by FCC/IC/CE/SRRC/Telec/KC/SRRC/NCC. With both modules added on the list, whole nRF52 series module road map now has become comprehensive and completed.
#nRF52805 SolutionMDBT42T series designed for highly cost constrained.
Bluetooth applications not always tough and complicated.
Most cases, Bluetooth applications are brief and require simple bridge functionality only such as UART service for Bluetooth Low Energy (BLE) or SPP for Classic Bluetooth (BT3 or BT2). Raytac adopted Nordic nRF52 base line solutions (nRF52805 / nRF52810 / nRF52811 / nRF52820) offer a series of base line modules with different form factor and antenna options for selection.
Excepting modules, Raytac even developed a firmware pre-loaded modules for base line solution which is called as AT command module series. AT command module collected a list of most common command that transparent transmission may need. A well developed firmware pre-loaded modules bring developers or customer a quick access to Bluetooth. Simply deploy the module onto applications and projects can be benefited with the maximum flexibility, design free, time saving advantage.
