Android M Preview Images & SDK and Key Changes

Google formally announced Android M (Marshmallow?) at Google I/O, and released preview images for Nexus 5, Nexus 6, Nexus 9, and the Nexus player. If you don’t own any of these devices, you can also run Android M in the emulator using the preview SDK. So what’s new in Android M? Google reports over 100 changes, but here are some of the highlights of improvements and new features: User Control of Permissions – With Android M, apps can trigger requests for permissions at runtime, and let users choose whether to allow it. For example, if your flashlight app suddenly request access to your contact list, a window may pop up and you are free to decline it. Users will also have easy access to manage all their app permissions in settings. Doze improves Battery Life – Android M will use motion detection to learn if a device has been used […]

Ambarella Unveils SL2m IP Camera Reference Design Promising up to 6 Months of Battery Life

Ambarella S2Lm IP Camera SoC features a Cortex A9 CPU core, encodes video with H.264 up to 3Mp30 / 1080p30, and targets consumer and entry-level IP Camera designs. The company recently launched a new battery-powered IP camera reference design based on the solution that promises up to 6 months battery life, and can record Full HD video in less than 500ms from wake up, making ideal for battery operated security cameras. A Linux SDK is also provided with reference implementations for low-power standby operation, wake-on-Wi-Fi and fast boot to Linux. Unfortunately, that’s about all we know about the reference design, so instead I’ll have a look at the processor, and SL2m IP camera evaluation board. Ambarella SL2m SoC specifications: CPU – ARM Cortex-A9 processor with 32KB/32KB I/D and 128 KB L2 Cache, NEON and FPU, Crypto Engine – AES/3/DES/SHA-1/MD5 DSP / VPU – Ambarella Image and Video DSPs Sensor and […]

PiJuice Battery HAT Module for the Raspberry Pi Boards Comes with an Optional Solar Panel (Crowdfunding)

The Raspberry Pi is a low power board that can be powered a few hours or a few days with batteries, and the easiest solution is probably to use a USB power bank connected to the micro USB port of the board, but the solution is not really integrated. That’s where PiJuice comes into play. It’s a HAT compatible module that connects nicely to the latest Raspberry Pi boards with 40-pin header (A+, B+ and B2), and include a 1,400 mAh battery that can be used as UPS (Uninterrupted Power Supply), an RTC, and more. Key features of PiJuice HAT: 1400 mAh Lipo battery, good enough to last up to 24 hrs in constant use. 5,000 mAh batteries are also said to be supported. Full UPS (Uninterrupted Power Supply) solution Integrated RTC (Real Time Clock) On board intelligent on/off switch Low power deep-sleep state with wake on interrupt/calendar event On […]
