8*16 LED matrix display with bluetooth low energy to connect to any smart phone. By Nitesh:
This LED matrix is a heart shaped circuit which you can make/buy(from me) and gift to your valentine or crush and spread your love. It can be worn as a necklace or as a badge. It has got BLE so you can display any text message on the necklace using a smart phone.
Acknowledged as the UK’s leading source of advanced embedded technology, Solid State Supplies Ltd. now offers the world’s smallest Bluetooth® Low Energy (BLE) SiP module from Silicon Labs. With a package size of 6.5mm x 6.5mm x 1.4mm the BGM11S Blue Gecko SiP (System in Package) module targets applications where ultra-small size, reliable high performance RF, low power consumption, full modular certification and easy application development are key requirements.
This highly integrated SiP solution is a complete Bluetooth subsystem with on-board radio transceiver, antenna, serial interfaces, core processor, memory, clock management, I/O, timers, triggers, hardware security and power management. (more…)
The new STM32WB from STMicroelectronics is a new wireless supporting System on a chip (SoC) that comes with a fully-featured ARM Cortex-M4 (@ 64 MHz) based microcontroller to run the main computing processes. It also has an ARM Cortex-M0+ core (@ 32 MHz) to offload the main processor and offer real-time operation on the Bluetooth Low Energy (BLE) 5 and IEEE 802.15.4 radio. The SoC can also run other wireless protocols as OpenThread, ZigBee® or other proprietary protocols. It opens many more options for connecting devices to the Internet of Things (IoT).
The Cortex-M4 combined with a Cortex-M0+ for network processing makes sure the STM32WB to be the latest ultra-low-power microcontroller to combine superior RF performance with longer battery life. The SoC also combines essential circuitry for connecting to the antenna. It also packs right amount user and system memory, hardware encryption, and customer-key storage for brand and IP protection.
These days, only a few manufacturers offer similar dual-processor wireless chips capable of managing the user application and the radio separately for maximum performance. Alternative chips typically utilize entry-level ARM Cortex-M industry-standard cores, which introduce technical limitations and very low amount of onboard flash memory.
The robust and low-power 2.4GHz radio consumes only 5.5mA in transmit mode of this new STM32WB and as little as 3.8mA when receiving. This device also include STM32 digital and analog peripherals that are engineered for low power consumption and complex functionalities, including timers, ultra-low-power comparators, 12/16-bit SAR ADC, a capacitive touch controller, LCD controller, and industry-standard connectivity including crystal-less USB 2.0 FS, I2C, SPI, SAI audio interface, and a Quad-SPI supporting execution in place.
STM32WB devices will be available in an array of 48-pin UQFN, 68-pin VQFN, or 100-pin WLCSP with up to 72 general-purpose I/Os (GPIO). Each can be specified with any of three memory configurations, giving a choice of 256KB Flash and 128KB RAM, 512KB-Flash/256KB-RAM, or 1MB-Flash/256KB-RAM.
Adding components from Ambiq Micro and Talent Highland, Fujitsu Electronics Europe has increased its Bluetooth Low Energy portfolio.
The additional products offer customers high integration, low power consumption and flexibility, says Fujitsu Electronics Europe (FEE), and it has produced the ClickBeetle reference platform (pictured) to facilitate the integration of Bluetooth Low Energy products into applications.
Ambiq Micro’s Bluetooth Low Energy components make Bluetooth Low Energy applications more powerful and efficient, claims FEE. The Cortex M4 in Apollo 2 operates at up to 48MHz at only 10-microA/MHz with a deep-sleep current of two micro A. Apollo 1 operates at up to 24MHz at 34-micro A/MHz and has a deep-sleep current of 143-nanoA. Additional components offer the possibility of lowering the deep-sleep current to 22-nanoA. Depending on the requirements, Ambiq Micro offers different bundle packages to combine its Apollo 1 and Apollo 2 microcontrollers or real time clocks with an EM9304 BLE communication chip. Combinations of microcontroller and Bluetooth Low Energy chips are suitable for high-performance applications, while combinations of real time clocks and Bluetooth Low Energy are ideal for cost-sensitive Bluetooth Low Energy beacons. Packages range from BGA, CSP and QFN packages. For very small applications, Ambiq Micro also offers a SoC that combines the Apollo 2 microcontroller and EM9304 BLE in a 4.0 x 4.0mm LGA package with 64 pins.
Customers who would like to integrate Bluetooth Low Energy further can also use a Talent Highland SIP. Components such as a DA14580 with ARM Cortex M0 16 MHz and 42kbyte RAM, 1Mbit SPI flash, crystals, passive components and antenna are bundled in a package measuring only 7.0 x 7.0mm. Thanks to the internal DC/DC converter, the small module also supports three and 1.5V batteries. Depending on the requirements, FEE customers can also create their own package with their own components.
FEE offers its reference platform, ClickBeetle, for application-oriented evaluation and development. It measures just 16 x 26mm and uses a hardware-independent fixed pin layout, making it easy to replace and evaluate Bluetooth Low Energy components, says Fujitsu.
Particle, which has been known for its collection of IoT focused development boards, and its Internet of Things (IoT) platform (Particle Cloud) has launched a new set of mesh network-enabled IoT development kits called Particle Mesh. Particle Mesh is expected to provide developers more insight into implementing mesh networking technology. They help to collect sensor data, exchange local messages, and share their connection to the cloud.
Particle Mesh features a new family of mesh-ready devices with Wi-Fi, BLE and LTE connectivity and also integrated with the Particle device cloud. Particle mesh consists of three main boards: The Argon, The Boron, and the Xenon. Each of these Particle Mesh boards has at least one form of outside connectivity option (LTE/3G/2G, Wi-Fi or Bluetooth) and an onboard mesh network hardware to facilitate setting up a mesh network for local communications between sensors and other particle mesh boards. All three devices are built around the Nordic nRF52840 MCU + BLE + mesh radio and follow the Adafruit Feather specification making it compatible with most Adafruit FeatherWing hardware accessories.

PIXO Pixel uses an ESP32 to control a matrix of 256(16×16) RGB LEDs. It is an IoT device that can display information via Wifi and BLE.
The PIXO Pixel is an open source RGB display that uses the very cool, APA102-2020 Addressable LED in a 16 x 16 array. These LEDs are very fast, bright, and tiny; only 2mm x 2mm! Controlling the LED matrix is an ESP32 which is a WiFi and BLE connected microcontroller than can be programmed using the Arduino IDE(Or MicroPython!). Together these make up a very cool desktop display that you can program to do pretty much anything you want. There is also an added proto board for if you want to add more components like an accelerometer, thermometer, light sensor, potentiometer, anything!

by Alice Matthews@ electronicspecifier.com discuss about MBN52832 a BLE module:
A Nordic-based BLE module has been released by Murata. The latest MBN52832 device consists of Nordic Semiconductor’s nRF52832 IC, a 32MHz crystal for timing, and an on-board antenna. Additionally, it contains pins for an off-board omni-directional antenna and a NFC antenna. The module provides a Serial Port Interface (SPI) and UART interface to Nordic’s nRF52832 ARM Cortex M4 processor.
Module provides BLE connectivity between tablets and cloud – [Link]
Electronut Labs recently released their open source Nordic nRF52832 development board that can be used for your next BLE project. This tiny board can be plugged on a breadboard or soldered on a PCB and provides additional value from just using the BLE module directly as it includes the necessary passive components, buck converter, RGB Led and push button. The board is available for sale on Tindie for 20 USD.
hackaBLE uses the Nordic nRF52832 which in turn is based on an ARM Cortex-M4 core. So you can really program it with any ARM compatible programmer. We do have a convenient solution though, in the form of our Bumpy blackmagic probe compatible SWD debugger and our PogoProg.
A smartwatch with fall and location detection, reminders and more, designed to help you or your loved one with Alzheimer’s!
When I saw Infineon’s Sensor Hub Nano, it appeared to be a good candidate in such a project, because of its very small size and BLE capabilities. With the accurate pressure sensing, it could be used to detect if the patient has fallen and also tell where exactly the patient is in the house.
