Android Set-top Boxes With Digital Satellite TV Receiver (DVB-S2)

There are now plenty of Android set-top boxes or HDMI TV sticks, but if you want to watch digital satellite or terrestrial TV, the options are limited. If you already have a satellite receiver at home, you could buy an Android set-top box with an HDMI input such as Huawei MediaQ M310, or use a DVB-S2 USB adapter, but you may need to acquire both the kernel source and DVB driver to compile it for your device. So for now, the last option is currently reserved for ODM/OEM as mentioned on Geniatech store. But today, I’m going to write about an Android set-top boxes that comes with a satellite receiver (DVB-S2). They are all based on AMLogic AML8726-M1/M3, and models include: Geniatech ATV1100B Hybrid DVB Box – Multiple standards STV-502 – DVB-S2 Monolithelec MINGLE – DVB-S2 Geniatech ATV1100B Key Features: SoC – AmLogic AML8726-M1 ARM Cortex A9 @ 800MHz System […]

Rockchip Unveils RK3168 Dual Core Processor, Showcases $10 Miracast Adapter

Rockchip is currently at the Hong Kong Electronics Fair showing off their RK3188 quad core processor, and corresponding products such as tablets, gamepads, HDMI TV dongles, etc… Business seems good as they already received orders for 800k pieces in about a month, and they expect to sell 10 to 15 millions over the course of the year. The company had also a few RK3066 devices on display, but more interestingly they announced RK3168, which also a dual core Cortex A9 processor, but with lower power consumption thanks to 28nm HKMG process, instead of the 40nm process used for Rockchip RK3066. They have a tablet prototype without battery connected to a power supply to show the power consumption, and the tablet under test consumes 280mA @ 3.8V (About 1 Watt) when decoding 1080p videos with the display brightness set to about 50%. Chen Feng, Vice President at Rockchip, explains that with […]

Allwinner Showcases A20, A31 and A31s Devices: Tablets, Phablets, Mini PCs, Projectors, Laptops, Development Boards…


Charbax is now at the China Sourcing Fair in Hong Kong, meeting and interviewing lots of Chinese companies. One of the companies I’ve been following is AllWinner because of their low-cost ARM Cortex processors, found in many Android devices, which somewhat support Linux. In the video below, we first learn they have shipped 1 million A31 in the last 4 months, A31s and A20 processors have been available since the end of March for phablets, and A20 price is supposed to be very close to A10. So products based on AllWinner A10 could be upgraded to AllWinner A20 for just a few dollars more as both SoC are (nearly) pin to pin compatible. By the way, if you’re interested in the Cubieboard, you may want to see this. We then go through lots of devices based on AllWinner SoC, albeit too fast to get many details, but the list may […]

MINIX To Launch Four New NEO Set-Top Boxes: X5+, X5 Mini, X3 & X7

MINIX is a company relatively well know for its Neo G4 mini PC and Neo X5 Android set-top box based on Rockchip RK3066. They’ve now announced 4 new devices for HKTDC Electronic Fair in Hong Kong: Neo X5+ – RK3066 Set-top box based on Neo X5, but with 2GB RAM instead of 1GB RAM. Neo X5 Mini – Low cost version of the Neo X5 with 8GB NAND Flash instead of 16GB, and missing Bluetooth support. Neo X3 – Android 4.1/4.2 Set-top box powered by AMLogic AML8726-M3 with 1GB RAM, 4GB Flash, and 802.11n Wi-Fi. No word about Ethernet support.

Keil RTX RTOS is Now Available for Energy Micro EFM32 MCUs

Energy Micro has recently announced the availability of the Keil RTX real-time operating system (RTOS) as part of its Simplicity Studio tool suite. The Keil RTX has been optimized for ARM Cortex-M processors to provide flexible scheduling and high-speed operation, and has been improved to enable an ultra-low power, deep-sleep mode between tasks. Energy Micro has implemented a tickless mode in Keil RTX. This mode allows the EFM32 Cortex M3 MCUs to wake up only when needed, either at a scheduled time or on an interrupt event. This results in much lower power consumption in sleep mode compared to other SysTick implementations. The video below shows the difference between SYSTICK mode where the system consumes about 2.7mA in active mode, and 830 uA in sleep mode to the new tickless mode where the MCU still consume the same amount of energy in Active mode, but only 1uA in sleep mode, […]
