U-Blox announces NINA-B3 Bluetooth 5 Wireless MCU Modules

Bluetooth 5 promises to quadrupling the range and double the bandwidth of Bluetooth LE connection. However, we’ve seen not all Bluetooth 5 solutions will provide all features in a comparison between Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Bluetooth 5 ready SoCs, as while all three platforms will handle the higher bandwidth just fine, only the nRF52840 will extend the range up to 4 times. That’s why you want want to make sure you get recent hardware capable of fully handling Bluetooth 5, and U-blox has just announced NINA-B3 Bluetooth 5 module series, based on nRF52840 SoC, that will both provide longer range and higher bandwidth. U-blox NINA-B3 module comes in two family flavors: NINA‑B31, comes pre‑flashed with u‑blox’s Connectivity Software, eliminating the need for embedded programming. Support for AT command set, and u-Blox low energy serial port service NINA‑B30 using nRF52840’s ARM Cortex-M4F as an “Open CPU” that allows […]

Nordic Semi nRF52840 vs nRF52832 vs nRF52810 Comparison for Bluetooth 5 Applications

Bluetooth 5 was formally introduced earlier this year with promises of four times the range, and twice the speed. Several companies offer chips that are compatible with the new standard, and among them Nordic Semi offers Bluetooth 5 ready solutions via nRF52840, nRF52832, nRF52810 Bluetooth SoCs. However, if you thought – like I did – that all three would provide the same Bluetooth 5 support with just some differences in memory, storage and performance, a comparison table put together by Raytac Corporation will show that among the three SoCs only nRF52840 will support the longer range, while the two older SoC only support the extra bandwidth offered by Bluetooth 5. I could find a blog post about a long range demo that confirms the above: Two nRF52840 Preview Development Kits (PDK) or nRF52832 Development Kits. A combination of the two different kits can also be used. Notice that if the […]

Nordic Thingy:52 Bluetooth 5 IoT Sensor Development Kit Targets Mobile & Web App Developers

Some developers may be interested in providing solutions for the Internet of Things, but they may not have the skills or interest in making their own hardware, and/or develop firmware, and just want to create demos or prototypes quickly, focusing on app development instead. Nordic Semiconductors has recently launched Thingy:52 IoT Sensor Kit with Bluetooth 5 & NFC connectivity, and various sensors for those developers. Nordic:52 IoT Sensor development kit (nRF6936) hardware specifications: MCU – Nordic Semi nRF52832 ARM Cortex-M4F Bluetooth 5 System on Chip (SoC) Connectivity – Bluetooth 5 LE and NFC Sensors Temperature,Humidity, Air pressure, Air quality (CO2 and TVOC), color and light intensity 9-axis motion sensing – Tap detection, orientation, step counter, quaternions, euler angles, rotation matrix, gravity vector, compass heading, raw accelerometer, gyroscope, and compass data Audio Speaker for playing prestored samples, tones, or sound streamed over BLE (8-bit 8 kHz LoFi) Microphone streaming (ADPCM compressed […]

Aconno Bluetooth 4.0 & 5 IoT Development Board Features an nRF52832 or nRF52840 Module, an e-Paper Display, Sensors and More

Bluetooth 5 is the latest iteration of Bluetooth with up to four times the speed and twice the range of Bluetooth 4.0 LE, and so far apart from Puck.js and Nordic Semi nRF52840 devkit, I had not seen many Bluetooth 5 IoT modules or boards. Aconno, a German startup, has designed ACD-52832 Bluetooth 4.0 / Thread / ANT+ IoT development board based on their own nRF52832 module, and equipped with some goodies like a black & white e-Paper display, a joystick, sensors, I/Os, etc… They’ve also launched an updated module with Bluetooth 5 using nFR52840 SoC. I don’t have the full details about the new module, but the nRF52832 module and devkit is interesting to look at, especially features should be similar. Aconno ACD-52832 board specifications: Wireless Module – ACN52832 based on Nordic Semi nRF52832 ARM Cortex-M4 @ 64 MHz SoC with Bluetooth Smart, ANT+, Thread, NFC, and 2.4 GHz […]

$24 Winkel Arduino Compatible Board Includes WiFi, Bluetooth, 2.4 GHz RF, and an RTC (Crowdfunding)

There are plenty of Arduino compatible boards with WiFi based on ESP8266 WiSoC going for around $5 to $10, and with ESP32 processor, we are starting to have $15 to $20 boards with both WiFi and Bluetooth, but while ESP-IDF SDK has been progressing nicely, some parts of Bluetooth functionality are still not implemented. Winkel board offers an interesting alternative by offering WiFi, Bluetooth, 2.4GHz ISM, and an RTC for $24. Winkel board specifications: MCU – Microchip/Atmel ATmega128 MCU @ 16 MHz with 128KB flash memory, 4KB SRAM, 4KB EEPROM Connectivity WiFi 802.11 b/g/n via ESP12E module based on ESP8266 Bluetooth 2.0 + EDR via HC-05 module RF Radio – NRF24l01 2.4 GHz ISM radio. (Note: It might be possible to use it for Bluetooth LE connection, see here and there). I/Os (through both Atmel MCU and ESP8266) 38x Digital I/Os 7x PWM Digital I/Os 8x Analog Inputs USB – […]
