Arduino Nano 33 BLE Sense Rev2 switches to BMI270 & BMM150 IMUs, HS3003 temperature & humidity sensor

Arduino Nano 33 BLE Sense Rev2 is a new revision of the Nano 33 BLE Sense machine learning board with basically the same functionality but some sensors have changed along with some other modifications “to improve the experience of the users”. The main changes are that STMicro LSM9DS1 9-axis IMU has been replaced by two IMUs from Bosch SensorTech, namely the BMI270 6-axis accelerometer and gyroscope, and the BMM150 3-axis magnetometer, a Renesas HS3003 temperature & humidity sensor has taken the place of an STMicro HTS221, and the microphone is now an MP34DT06JTR from STMicro instead of an MP34DT05. All of the replaced parts are from STMicro, so it’s quite possible the second revision of the board was mostly to address supply issues. Arduino Nano 33 BLE Sense Rev2 (ABX00069) specifications: Wireless Module – U-blox NINA-B306 module powered by a Nordic Semi nRF52840 Arm Cortex-M4F microcontroller @ 64MHz with 1MB […]

MediaTek Dimensity 7200 Armv9 Cortex-A715/A510 processor targets mainstream 5G smartphones

Manufactured with a 4nm processor, the MediaTek Dimensity 7200 is an octa-core Armv9 processor designed for mainstream smartphones. with two Cortex-A715 cores, six Cortex-A510 cores, a Mali-G610 MC4 GPU, as well as 5G, WiFi 6E, and Bluetooth 5.3 connectivity. So far, I had only seen Armv9 SoCs with a mix of Cortex-A510 “LITTLE” cores, Cortex-A710/A715 “big” core, and Cortex-X2 or Cortex-X3 “flagship cores” as found in the Dimensity 9200 processor,  but the Dimensity 7200 is one of the first Armv9 processors – one other being the Snapdragon 7 Gen 1 – without a Cortex-X core in order to provide a more affordable solution. MediaTek Dimensity 7200 specifications: CPU 2x Arm Cortex-A715 up to 2.8GHz 6x Arm Cortex-A510 2MB L3 cache GPU – Arm Mali-G610 MC4 with MediaTek HyperEngine 5.0 APU – MediaTek APU 650 AI accelerator DPU/VPU – MediaTek MiraVision 765 engine for display and 4K HDR video decoding/encoding Memory […]

Raspberry Pi Pico W gets Bluetooth support in SDK 1.5.0

The Raspberry Pi Pico W board was launched with a WiFi 4 and Bluetooth 5.2 module based on the Infineon CYW43439 wireless chip in June 2022, and I wrote a tutorial showing how to connect to WiFi a few days after the launch, but nothing about Bluetooth. That’s because while the Raspberry Pi Pico W hardware supports Bluetooth, we were told that Bluetooth was not enabled at the time, but might be at a later stage. Alasdair Allan, who is responsible for the Raspberry Pi documentation, said Bluetooth support was scheduled very soon, and the SDK 1.5.0 release of the Pico C SDK is now available with Bluetooth implemented using BTstack low footprint dual-mode Bluetooth stack. Bluetooth support is still considered Beta and the SDK 1.5.0 implements the following key features and updates: New libraries for Bluetooth Low Energy (LE) support. Bluetooth Classic support. Bluetooth Sub Band Coding (SBC) encoder […]

Bluetooth 5.4 adds electronic shelf label (ESL) support

The Bluetooth Special Interest Group (SIG) has just adopted the Bluetooth 5.4 Core Specification with features such as PAwR and EAD designed for Electronic Shelf Label (ESL) systems. The Bluetooth 5.3 Core Specification was adopted in August 2021 with various improvements, and Bluetooth 5.4 now follows with features that appear to be mainly interesting for large-scale Bluetooth networks with support for bi-directional communication with thousands of end nodes from a single access point, as would be the case for Electronic Shelf Label or Shelf Sensor systems. Four new features have been added to Bluetooth 5.4: Periodic Advertising with Responses (PAwR) – PAwR is a new Bluetooth Low Energy (LE) logical transport that provides a way to perform energy-efficient, bi-directional, communication in a large-scale one-to-many topology with up to up to 32,640 devices. Devices can also be allocated to groups allowing them to listen only to their group’s transmissions. An Electronic […]
