nRF52840 Module MDBT50Q Series Bluetooth & RF Safety Certification Granted

Following Raytac’s Easy Employ Policy (EE), we are glad to announce that Raytac’s nRF52840 modules, MDBT50Q series have completed not only Bluetooth BQB certified, but also most popular countries’s safety regulation granted.

With the effort to provide a most coverage of the regulation compliance, developers who build up the IoT project by Raytac modules can be easier to develop without worry for product testing and manage the budget of development.

MDBT50Q powered by Nordic nRF52840 solution is a multi-protocol Bluetooth 5, Thread, IEEE 802.15.4, Zigbee, ANT+ solution incorporated 1MB flash memory, 256K RAM, built-in USB interface, supporting 5.5V DC/DC supply which is an edge cutting, ultra lower power solution ideal for all IoT applications. With completed pre-certified coverage, it bring the benefit for customers by reducing the design complexity, BOM cost and faster the Time-To-Market efficiency.

Raytac BT5 MDBT50Q-U External Antenna Type Module (Nordic nRF52840 Solution) Now Is Available

Bluetooth 5 grabs the attention may drop in “Long Range Feature”!

Compare to BT4.X BLE module in the market, mostly reach only about 20~30M.

Even Raytac’s BT4.X series modules, the best performance may about 100~140M line of sight.

Recent released MDBT50Q series, deploy Nordic nRF52840 has dramatically break the barrier of connectivity rage.

Upon the test under 1M bps  / sending data and link maintain, the connectivity range has reached over 340M.

1. BQB Qualification

藍牙的測試一般稱為 BQB


一是RF PHY 的硬體測試 , 其二是藍牙Profile 的相容性測試

模組唯有具備兩者測試者並依此申請 DID (Declaration)者, 才有辦法稱為是一個完全模組


勁達國際電子的模組 MDBT40/MDBT40-P 不僅已通過硬體的RF PHY 測試 , Profile 的相容性測試更囊括所有 Nordic 的profile

並依此申請 DID (Declaration ID)

因此,  客戶使用勁達所生產的模組是可以泛用於完全模組政策, 意即可以把日後的所有藍牙產品登錄在一個相同的 DID 之下的Product List

不需再為各別產品一一送測及購買 DID


2. 地區性的無線法規Regional RF Safety Regulation

很多勁達的客戶很好奇, 為什麼勁達的模組鐵蓋上打了密密麻麻的字

主要是因為, 勁達的模組是遵循完全模組政策


1. 獨立的天線

2. 需有鐵蓋遮蔽

3. 鐵蓋上必須有各國法規要求的文字


不同於BQB, 地區性的無線法規是各國海關邊境與市售的強制要求



除歐盟與澳洲外 , 客戶的成品都可以依照完全模組政策免測RF 的安規項目

A Bluetooth module needs to have 2 factors certification.
1. BQB Qualification
BQB testing is including RF PHY & Profiles interoperability testing.
Module only applied BQB with BOTH 2 tests can comply with Module Policy.
SIG Declaration ID (also known as DID) is essential.
Raytac’s MDBT40/MDBT40-P module past hardware RF PHY testing but also has past all Nordic profiles interoperability tests.
As such, customers who is using Raytac’s module to build up the products can follow the Module Policy  which means can just sublist all products under single DID’s Product List without applying another.
2. Regional RF Safety Regulation
Many of Raytac’s customers are curious why Raytac modules have so many no. on the shielding case.
Similar to BQB qualification, to have Antenna+Shielding case+ Qualification Report No. on shielding is essential condition to comply Module Policy for regional RF Safety Regulation.
Different from BQB, Regional RF Safety Regulation is law enforce issue in custom for every border.
Raytac’ MDBT40/MDBT40-P has complied following safety regulation in different countries by Module Policy.
Excepting CE and RCM which are not conducting Module policy, Raytac modules can bring a easy way for all customers to save time and cost without further regulation testing again in finished products.
