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.
Raytac announced both MDBT50Q-512K & MDBT50Q-P1M modules has extended the ambient temperature up to 105°C, following Nordic’s nRF52833’s specification.
Unlike a single component like SoC, modules acted as an integrated equipment which includes some other related components. To secure the module works under the latest environment request while Nordic nRF52833 released, Raytac ensured all related components meet the new temperature requirement with RF efficiency secured.
Today, we are pleased to announce nRF52833 modules:
MDBT50Q-512K: Chip Antenna
MDBT50Q-P512K: PCB Antenna
Both have successfully extended ambient temperature to 105°C which are the most ideal devices for a wide range of commercial and industrial applications.

A BT5.2 & BT5.1 & BT5 & BT 4.2 module maker based on Nordic nRF52 & nRF51 solution
Nordic announced their 6th multi-protocol solution of nRF52 series with nRF52820, which supports Bluetooth Low Energy (BLE), Bluetooth mesh, Thread, Zigbee and 2.4GHz proprietary wireless connectivity.
Like other nRF52 siblings, nRF52820 highlights a powerful 64MHz 32bit Arm Cortex-M4 processor, includes 256Kb Flash Memory and 32Kb RAM, features of Bluetooth 5.2, 5.1 and 5 including long range and high-throughput of 2Mbits per second, as well as direction finding, low energy power control and low energy isochronous channels.
A full speed (12Mbits per second) USB 2.0 interface and 1.7~5.5V operation voltage bring a wide range of commercial and industrial wireless applications to nRF52820. To support nRF52820’s development, Nordic released SoftDevice S112, a new memory-optimized central stack. S112 now released as a alpha and will have full SDK (SDK V16.0.0) support coming in Q2 2020.
Developer who currently are using nRF52840 based modules must be excited waiting for nRF52833’s distribution. Most developers are aware that nRF52833 supports long range, multi protocol and USB interface but has less RAM and Flash memory rather than nRF52840 and no doubt is the best alternative to have cost effective without extra efforts.
Raytac has released 3 models of nRF52833 based modules just at the same time when Nordic released, MDBT50Q-512K / MDBT50Q-P512K / MDBT50Q-U512K. Both nRF52840 and nRF52833 module are based on same form factor and pin out. To have quick visual identification finding the difference, Raytac’s nRF52833 modules are built by Green PCB but nRF52840 modules are Blue.
Nordic’s nRF52833 is an advanced mulitiprotocol SoC solution which supporting not only Bluetooth mesh, Thread, Zigbee but also latest BT5.1 direction finding capable radio. The solution is built around 64MHz Arm Cortex-M4 FPU, 512KB flash memory, and 128KB RAM memory with an extended industrial standard working temperature range of -40 °C to 105°C which is an ideal solution for commercial and industrial applications.
Raytac Corporation, a Taiwan based Bluetooth module maker, has selected Nordic nRF52833 solution building up MDBT50Q series modules. MDBT50Q series modules provide 3 kinds of antenna options (Chip Ceramic / PCB / u.FL connector for external antenna) brings the best usability to meet different implements. The modules have BT5.1 certification and FCC/IC/CE/RCM/Telec/KC/SRRC/NCC/WPC pre-certified, which are the optimized solution that makes it attractive in a very wide range of applications from a performance, time-to-market efficiency, and minimal Bill of Material (BOM) perspective.
MDBT50Q /nRF52833 modules is expected to have mass production by 2019/11, customer who are interested in nRF52833 series module may visit Raytac website for more information.
Hi there, folks!
So you have hopefully downloaded your IDE, you have written your code which you then plan to copy it over onto your MDBT50Q-RX and make it execute your master plan to take over the world!
Seriously, don’t underestimate the Nordic nRF52840 based MDBT50Q-RX. USB sticks with Bluetooth can do wonders 😉
So, first of all, in order to be able to burn your code onto the USB Dongle, you will have to know the nerdy parts which includes which pins you will have to connect to. In our very well documented specification sheet for MDBT50Q-RX on section 8 which is called “Reference Circuit”, you will find parts down to the left that has “3.3V/SWDIO/SWCLK/GND” marks on it:
Further down in the specification sheet, in section 9, you will find pictures illustrating where exactly on the PCB you can find these pins:
Now we know what to look for and where they are, so now we have only got to tell you how to use them.
Some people might not know this, but for developing these things, you need to get something called J-Link to connect your MDBT50Q-RX to your desktop. However, since this J-Link, when buying the official one from SEGGER, is very expensive, we strongly recommend you to just buy the nRF52840-DK from Nordic Semiconductor as it can be used as a J-Link through their software development kit (SDK) called nRFgo Studio and is MUCH CHEAPER than the official J-Link from SEGGER is.
Sidenote: There are a couple of other reasons why you should just get your hands on a nRF52840-DK from Nordic Semiconductor instead of getting a SEGGER J-Link, but that’s not the topic of this post 😉
When this is done, this is finally how you connect your MDBT50Q-RX to your J-Link to make it all work:
Here you will have to pay attention to the fact that you have to connect J-Link pins 3, 5 & 9 to GND. Otherwise, you won’t be able to burn anything onto your dear MDBT50Q-RX.
The physical connection should look like this:
Pay attention to the direction of the cable, because that will also matter. The direction we mean in this case is which way the slim strip of red is facing.
