Raytac Corporation, a recommended 3rd-party module maker by Nordic Semiconductor, announced that MDBT42Q series module now provide a Reel Package option for customers’ selection.

Raytac Corporation, a recommended 3rd-party module maker by Nordic Semiconductor, announced that MDBT42Q series module now provide a Reel Package option for customers’ selection.

With coming depreciation and withdraw of Legacy Bluetooth Core Specification Version, BT4.1/BT4.0 has been defined to be withdraw in 1 July, 2020, which covered Nordic’s nRF51 series solution (Raytac MDBT40 series module).
To resolve this issue, Raytac has updated the MDBT40’s Bluetooth specification to BT4.2 with DID: D042310. Raytac MDBT40/MDBT40-P/MDBT40-n designed based on Nordic nRF51xxx SoC with integrated Bluetooth 4.2, Bluetooth 4.1, and Bluetooth 4.0 stack. MDBT40/MDBT40-P/MDBT40-n module incorporates: GPIO, UART, SPI, I2C, and ADC interfaces for connecting peripherals and sensors. The modules are all FCC/IC/Telec/CE/KC/SRRC/NCC/ANATEL/RCM pre-certified (MDBT40-P includes CNC/IFETEL), which can speed up customers’ easy hardware design, reduce BOM cost, and enhance Time-To-Market efficiency
The granted BT4.2 DID includes not only basic GATT, RF PHY and Link Layer, but also a completed coverage of BLE software stack: Proximity Profile; Heart Rate Profile; Health Thermometer Profile; Blood Pressure Profile; Running Speed & Cadence Profile; HID Over GATT Profile; Alert Notification Profile; Glucose Profile; Cycling Speed & Cadence Profile ; Mesh Profile which fully support customers to suit the needs of any application!



AT command module, an easy solution provides developers a quick breakthrough to Bluetooth connection. Without firmware effort needed, simply have commands setting on MCU and the start to enjoy the implement of bridging connectivity between devices through Bluetooth.

After Raytac’s Peripheral (Salve) role AT command module released, the demand of Central role has been highlighted by developers.
To have a completed solution, Raytac today announced Central role, as known as Master, AT command module released.
Part No.:
MDBT42Q-ATM (Chip Antenna Version)
MDBT42Q-PATM (PCB Antenna Version)

Differ from Peripheral role AT command module built by nRF52810 solution, Central role AT command module deployed Nordic nRF52832 which employees 64K RAM and 512K Flash Memory.


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.

Raytac’s EE policy (Easy Employee) core is to provide the pre-certified modules.
Benefits from this policy, products built by Raytac’s module may save or reduce the procedure in certification application process which successfully improved Time To Market efficiency and Cost Effective for all customers.
Raytac’s latest module, MDBT50Q series module employed Nordic nRF52840 solution has developed 3 lines with different antenna type.
MDBT50Q-1M: Chip Antenna
MDBT50Q-P1M: PCB Antenna
MDBT50Q-U1M: u.FL connector with external Antenna.
We are glad to announce that MDBT50Q series modules have FCC Part 15 C Regulation Certificated granted with FCC ID: SH6MDBT50Q.
FCC Category: Portable Device
Product Name: Bluetooth Low Energy & IEEE802.15.4 Combo Module
Certified Protocol : BT5 & IEEE 802.15.4

Certification Item
MDBT50Q-1M (Chip Antenna Version)
MDBT50Q-P1M (PCB Antenna Version)
MDBT50Q-U1M (External Antenna Version, Listed in below)

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.
