Nordic nRF52820 Module By Raytac

Raytac released MDBT50 series module which deployed Nordic latest 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.

Nordic nRF52805 module / MDBT42T Series By Raytac Corporation

Raytac announced nRF52805 module, MDBT42T series, has moved to mass production stage. 

MDBT42T series module deployed nRF52805 WLCSP package combined with Raytac's experienced RF design, provides a 7.2 x 11.2 mm dimension which is optimized for size constrained applications.

MDBT42T module provide 2 antenna options for customer's selection:

Chip Antenna: MDBT42T-192K: 7.2 x 11.2 x 2.05 mm

PCB Antenna: MDBT42T-P192K: 7.2 x 11.2 x 1.8 mm

Nordic nRF52820 solution, MDBT50 series Module by Raytac

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.

BLE Module Firmware Development Q&A: NFC pins creates “Error 404 – signal not found” (technically)

When you start developing your firmware for your Nordic nRF52832 solution-based Raytac BLE module, you will (like on most other projects) bump into some difficulties.

The other day, we had yet another case where a simple thing caused major difficulties for even some of the brightest people – a customer couldn’t get their GPIO direction bit to work.

Although not too difficult to solve, it’s a common error that most customers end up having on our modules and that is because Pin 0.09 & 0.10 are set to NFC per Nordic’s default settings. In order to be able to use these pins as normal GPIOs, you will have to change those settings.

The two pins I am talking about are the ones linked to the NFC-part to the far left in the circuit example below:

So, to convert these two pins to normal GPIOs, here’s what you need to do:

In SES, you’ll need to add CONFIG_NFCT_PINS_AS_GPIOS.

Right-click on the project and click “Edit Options”

Select “Common”, click on “Preprocessor” under “Code” and then click “CONFIG_NFCT_PINS_AS_GPIOS”

Check out the link below for a reference example on Nordic’s DevZone.
