Pyboard MicroPython ARM Cortex M4 Board is Now Available for $45

MicroPython is both a lightweight implementation of Python 3.4 programming language, and a board, aka pyBoard, based on STMicro STM32F4 ARM Cortex M4 micro-controller running Micro Python. The project had a successful Kickstarter campaign in 2013, and they’ve completed shipment of the perks to their backers last June. The company has now launched its own store, so let’s see the progress of the project. The board has been re-designed since Kickstarter campaign, but the specifications remains the similar, but with some extra I/Os exposed: MCU – STMicro STM32F405RG micro-controller @ 168 MHz with 1MB flash, 192KB RAM, and an FPU. External Storage – Micro SD card slot, supporting standard and high capacity SD cards Expansion Headers: 24x GPIO on left and right edges and 5x GPIO on bottom row, plus LED and switch GPIO available on bottom row 3x 12-bit analog to digital converters, available on 16 pins, 4 with […]

Rikomagic Announces MK902II LE Ubuntu Mini PC Powered by Rockchip RK3288 SoC

Rikomagic announced their MK902II mini PC based on Rockchip RK3288 in May, and which has started shipping recently for about $130. The company have now announced MK902II LE (Linux Edition) based on the same hardware, but instead of running Android 4.4, it’s running Xubuntu 14.04 with some virtualization technique that allows it to run x86 Linux programs such as Skype, and it can even support Wine to run Windows programs. MK902II LE specifications: SoC – Rockchip RK3288 Quad Core Cortex A12/A17 up to 1.8GHz with ARM Mali-T764 GPU supporting OpenGL ES1.1/2.0/3.0, Open VG1.1, OpenCL, DirectX11 System Memory – 2GB (Dual channel 64 bit DRAM controller) Storage – 16GB Internal eMMC with Xubuntu 14.04 preinstalled + micro SD card slot Video Output- HDMI (1080p), and AV output Audio Output – HDMI, AV output, optical output, or external USB audio card (not included) Connectivity – Gigabit Ethernet, 802.11 b/g/n Wi-Fi.

Performance Comparison of Amlogic S805 and S802 Processors

Amlogic S805 is a quad core Cortex A5 processor for entry levels Android media players, S802 is a quad core processor with faster Cortex A9 cores clocked @ 2.0 GHz, and S812 is an upcoming upgrade of S802 with HEVC/H.265 hardware video decoding, and Gigabit Ethernet support. I’ve already written about the features differences between AML8726-MX, S802, S805, and S812, but since I now have some devices I can make direct comparison between S802 and S805. It’s quite clear on paper than S802 should be significantly faster than S805, so the only question to answer is by how much, but I’ve been asked to do it, and it could be a fun exercise. The hardware devices used for the comparison are two Android media players: EM6Q-MXQ for S805 and Probox2 EX for S802, and I used the results from three Android benchmarks: Antutu 5.1, Vellamo 3.x, and 3Dmark Ice Storm […]

Rockchip RK3126, RK3128, and “MayBach” Octo-core Cortex A53 Processor Could Be Found in Tablets in Q4 2014

T-chip, the company behind Firefly-RK3288 development board and HPH NT-V6 media player, has sent me their latest company brochure this morning. The brochure mentions the company history since 2005, various tablets solutions they have done over the year, and new and upcoming products. One of the slides particularly caught my attention. RK3288 is pretty popular right now, but I had never heard about RK3126 and RK3128 SoC with four ARM Cortex A7 core with a Mali GPU supporting HEVC decoding up to 1080p resolution. Both processors are manufactured using 40nm technology, so I’d guess these target ultra low cost tablets, which should become available in October and November 2014. Even more interesting is the mention of “MayBach” Tablets. I’ve been told MayBach, which could just be a temporary codename, is an upcoming Rockchip SoC. Based on the information in the slide, it should be an Octa-core Cortex A53 processor with […]
