Reliability test is the measure which helps to predict future behavior during a period of usage of the product, component or material. In combination with the measurement of relevant parameters and the use of appropriate test methods, reliability test helps to ensure the function and qualify of the product or feature can perform as designated.
Nowadays, Bluetooth module has become the most important key part within whole IoT system, It is not only controlling the connection but also computing. Raytac understood how critical the module need to perform in the system no matter commercial or industrial applications. Therefore, Raytac conduct the reliability testing plans for all series modules in order to ensure all the module‘s duration can meet design request.
The Reliability test is following JASO D001-94, Clause 5.12, and testings are under below 3 environments.
Low temperature maintain test under -40℃ and last for 72hr
High temperature maintain test under 105℃ and last for 72hr
Thermal shock testing under -40℃~105℃
Raytac’s modules have been recorded No data loss over Total 252,979,200 bytes communication during the test. The perfect result proof not only IC but also all components in the module are qualified to work for you!
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.
nRF51422 is the first solution supports both Bluetooth and ANT+, different from pure Bluetooth Low Energy BLE solution, nRF51822 released earlier. The edge cutting technology enable nRF51422 suporting multiprotocol concurrency capable for both Bluetooth Low Energy and ANT+. At the same time Nordic released SDK S310 for nRF51422 which is a combined peripheral BLE and ANT+ protocol stack that supports concurrent operation and all ANT+ features.
When Nordic moved to nRF52, started from nRF52832, the game changed. Even nF52832 still supports ANT+, the technology support such as SDK releasing or developers’ forums, has moved to direct supported by ANT+ Wireless (formerly Dynastream Innovations). Since then, Raytac suggest developers who is interested in ANT+ product still able to select the modules based on core specification and form factor, but access the firmware development support from ANT+ directly. Developers who are interested to know more about ANT+ is encouraged visit ANT+ FAQ support page first for more information about membership, development, resource and certification.
All Nordic nRF52 solutions supports ANT+ feature, developers may refer to below Raytac module map and find what the protocol supports by the symbol stated besides the Nordic solution indication.
With Internet of Things (IoT) technology being the talk of the town for years, Bluetooth obviously has become the most important solutions for short and middle range device connection.
Raytac Corporation, a specialized module maker, adapted Nordic solution among various solution providers, developed a rage of modules with different form factors, antenna options and feature capabilities to optimize and simplify the design and development experience. By this comprehensive product line provided, project feasibility would never be the challenge for all developers.
The pertinent support need out of projects Raytac has been experienced is the accessibility of module design reference, in term of 2D (autocad), 3D (Step / ProE), footprint, reflow, and keep out area suggestion information. To provide a convenient and free to use resource library for developers is seriously been considered. Therefore, Raytac has created a support page in the website, loaded in all the essential design guide information based on all modules. Thus, developers all over the world can just simply click the website and obtain the immediate design information without taking time in back and forth mail communications. This does significantly save the developing schedule up to 2~3 days at least.
Raytac keep improving to make things easier. Any idea you expect from Raytac, feel free to let us know~
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.

Outside the home in the frozen world. Raytac take care!
Winter is coming and field is chilly. Stay home enjoy the warm is what people is looking for.To ensure users enjoy the joyful time on couch, Raytac conduct a 72 hrs non-stop connection reliability test under -40°C which is compliant with industrial standard. 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.
