Broadcom Introduces WICED Sense Bluetooth Low Energy Development Kit

Broadcom has recently announced a new development board for IoT applications using Bluetooth Low Energy (BLE) called WICED Sense. The kit consists of a “sense tag” powered by the company’s BCM20737S Bluetooth SIP Module with five micro-electromechanical sensors (MEMS), and Bluetooth 4.1 compatible WICED SMART software stack. The key features of WICED Sense devkit are as follows: Broadcom BCM20737 Bluetooth Smart system in package (SiP) module Five low-power MEMS sensors by ST Micro (part of the module): Gyroscope (L3GD20) Accelerometer (LIS3DSH) eCompass (LSM303D) Pressure sensor (LPS25H) Humidity Temperature sensor (HTS221) Bluetooth Smart connection covers distance of roughly 30 meters. USB – 1x micro USB connector to update applications Encryption, decryption, certificate signing, verification and various algorithms for increased privacy Secure Over-the-air (OTA) download capability to enable firmware updates from central device including smartphone, tablet and computers Misc – iBeacon, NFC, Wireless charging (Rezence A4WP) support. Power – Coin-cell battery The […]

Freescale WaRPBoard Reference Platform for Wearables is Now Available for Pre-order

Back in January, Freescale announced WaRP (Wearable Reference Platform) comprised of the WaRPboard, a tiny board based on Freescale i.MX 6SoloLite running Android, and a daughter board with KL16 Cortex M0+ MCU and several sensors. The company collaborated with Revolution Robotics for the hardware design, and Kynetics for the software, and the platform is now available for pre-order for $149, and a few more details have surfaced since my first article. The hardware specifications of WaRP are as follows: WaRPboard: SoC – Freescale i.MX 6SoloLite Cortex A9 processor @ 1GHz with 2D graphics Vivante GC355 and  GC320 GPUs. System Memory – LPDDR2 (Micron Multi-Chip Package) Storage – 4Gbit eMMC  (Same Micron MCP chip as for RAM) Connectivity – WLAN and Bluetooth 4.0 LE via Murata LBEH17YSHC Display I/F: MIPI DSI for LCD display + touchscreen EPCD for E-Ink Display Sensors – Xtrinsic FXOS8700CQ, 6-Axis Sensor with Integrated Linear Accelerometer and Magnetometer. Daughtercard: […]

AW4P’s Rezence Specifications Now Support Wireless Charging for Laptops up to 50W

At the end of last year I wrote about Rezence, one of the existing wireless charging standards using magnetic resonance, which does not require end-users to perfectly align their mobile devices to charge them properly. At the time, specifications to charge feature phones and smartphone were already available, but the Alliance for Wireless Power (A4WP) was also working on defining the requirements to charge laptops wirelessly. Work is now mostly complete, and A4WP has announced specifications supporting 50W wireless charging capable of charging your laptop, smartphones, and tablets simultaneously by simply placing the device on or close to a charging surface, without having to performance any specific alignment. The organization expects publication and upgrade to the existing Baseline System Specification and certification program by the end of 2014, and they’ve also announced over 100 companies have already joined A4WP including silicon vendors such as Broadcom, Mediatek Intel and Qualcomm, as well as devices manufacturers such as Dell, Fujitsu, Foxconn, Lenovo, Logitech and […]
