Intel Smartwatches are Hot! So Hot, They May Burn Your Skin

Low power in constrained spaces is a tricky business, even for ARM based SoCs with the Qualcomm 810 overheating saga a few months ago. Now it’s time for Intel to feel the heat, as the company has has to recall Basis Peak smartwatches / fitness trackers due to potential overheating causing skin burns. Josh Walden – senior vice president and general manager of the New Technology Group at Intel Corporation – stated: On behalf of the Basis Science team, I want to personally apologise for this situation, we know that many of you love using your Basis Peak watches and have made them part of your daily lives, and we are very sorry for the disruption this will cause you, we had hoped to update the software on your watch to address the problem, unfortunately, despite our best efforts, we aren’t able to develop such a solution without completely compromising […]

Thunderboard Wear is a $75 Smartwatch Development Board by Silicon Labs

A few days ago I watched an ARMDevices.net’s video about an ARM’s smartwatch reference design running mbed OS 3.0, powered by a Silicon Labs EFM32 Giant Gecko Cortex M3 MCU, and promising up to 2 months battery life on a 160 mAh battery. While I could not find the full details about the reference design, I noticed Silicon Labs also launched a development board called Thunderboard Wear, based on the same platform, just quite bigger, and still wearable… (Sort of) Thunderboard Wear specifications: MCU – Silicon Labs EFM32GG995F1024 ARM Cortex-M3 MCU up to 48 MHz with 128 kB RAM,1 MB Flash External Memory – 256 kB external SRAM External Storage – micro SD card slot Display – 128×128 pixel Memory LCD from Sharp Connectivity – Bluetooth 4.1 smart module (Silicon Labs BGM111), upgradeable to Bluetooth 4.2 Sensors Ambient Light Sensing (ALS) and Proximity/Gesture via Silicon Labs Si1141.
