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.
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.

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.
Standing on marketing perspective point of view, iPhone user are often been viewed as a higher contribution margin group. Not only talking about consumer behavior, but also the motivation looking for device integrated with their own iOS devices. That explains why HomeKit devices recently has been widely spreading out in Apple stores or shops.
Wireless technology, says Bluetooth or WiFi, is the key role to connect between devices for Apple HomeKit implements. Surely, Bluetooth is more applicable than WiFi, not only easier to connect to iOS devices but also much lower power consumption and higher security level to rich consumer’s experience.
Raytac has been devoting to Bluetooth Low Energy module development for several years, started from BT4.0 to the latest. Raytac modules has selected Nordic’s solution, which is a highly optimized solution running HomeKit Accessory Protocol (HAP) and application firmware. The ultra-low power even enhance the design and usability for HomeKit devices implements.
After MFi Licenses program jointed, Nordic nRF5 HomeKit SDK is capable to access, Raytac expects to escalate the support ability in terms of hardware and firmware aspects for all customers who are interested in Apple HomeKit implements.

From IC Revision 1 to 2While there are quite a few changes available for review in the nRF52840 documentation, there is update that is particularly important for many users out there, including a large amount of our own customers. The update I am talking about is about the power supply.
First things first – if you’re interested in reading the whole documentation for Nordic Semiconductor’s nRF52840, then look no further than their Infocenter.
As you can see in the picture below, there’s a lot of information about LDO and DC/DC regulators. That is exactly the main topic of today’s post.
On nRF52840 version C, when changing from 5.5V to 3.3V, you had to use LDO mode in order for the chip to function properly. In the new chip version 2, you won’t have to change to LDO mode as you can directly use REG0 DC to DC.
I will let the Infocenter documentation speak for how it works in detail as quoted below:
The system contains two main supply regulator stages, REG0 and REG1.
Each regulator stage has the following regulator type options:
Low-dropout regulator (LDO)
Buck regulator (DC/DC)
In normal voltage mode, only the REG1 regulator stage is used and the REG0 stage is automatically disabled. In high voltage mode, both regulator stages (REG0 and REG1) are used. The output voltage of REG0 can be configured in register REGOUT0. This output voltage is connected to VDD and is the input voltage to REG1.
By default, the LDO regulators are enabled and the DC/DC regulators are disabled. Registers DCDCEN0 and DCDCEN are used to independently enable the DC/DC regulators for the two stages (REG0 and REG1 respectively).
When a DC/DC converter is enabled, the LDO for the corresponding regulator stage will be disabled. External LC filters must be connected for each of the DC/DC regulators being used. The advantage of using a DC/DC regulator is that the overall power consumption is normally reduced as the efficiency of such a regulator is higher than that of a LDO. The efficiency benefit of using a DC/DC regulator becomes particularly prominent when the regulator voltage drop (difference between input and output voltage) is high. The efficiency of internal regulators vary with the supply voltage and the current drawn from the regulators.
Note: Do not enable DC/DC regulator without an external LC filter being connected as this will inhibit device operation, including debug access, until an LC filter is connected.
We hope you get a better understanding about the update from nRF52840 Revision 1 to 2 and its power supply.
Raytac now has started supply module demo board, MDBT50Q-DB, build by nRF52840 v2 SoC.
If you would like to purchase our MDBT50Q-DB demo board (deployed module: MDBT50Q-1MV2) on it, you can get one on eBay or Verical.
We at Raytac wish you all a nice day and happy tinkering 🙂
