Raspberry Pi 3 Compute Modules CM3 and CM3L Launched for $30 and $25

We all knew Raspberry Pi Compute Module 3 were about to be launched soon, as the Raspberry Pi foundation announced a partnership with NEC displays last October, and the datasheet for two version of the Broadcom BCM2837 based system-on-module, CM3 and CM3L (Light), was released shortly after. The good news is that the modules have officially been launched for $30 and $25 for respectively Compute Module 3 with 4GB flash, and Compute Module 3 Light with the SD card signals exposed via the SO-DIMM connector. The foundation has also lowered the original compute module price to $25. Here are Compute Module 3 specifications as a reminder: SoC – Broadcom BCM2837 quad core Cortex A53 processor @ 1.2 GHz with Videocore IV GPU System Memory – 1GB LPDDR2 Storage CM3L – SD card signals through SO-DIMM connector CM3 – 4GB eMMC flash 200-pin edge connector with: 48x GPIO 2x I2C, 2x SPI, […]

ASUS Tinker Board is a Raspberry Pi 3 Alternative based on Rockchip RK3288 Processor

Regular readers may remember MQMaker MiQi board, a $35 (and up) development board powered by Rockchip RK3288 quad core ARM Cortex A17 processor, based on Raspberry Pi 3 form factor, but much faster according to benchmarks. Sadly, the board’s crowdfunding campaign was not that successful, possibly because of the “its’ a 2-year old processor” syndrome. But now, Minimachines has found that ASUS has designed a very similar board, dubbed Tinker Board, with an extra WiFi and Bluetooth LE module, audio jack, MIPI DSI connector, and a few other modifications. Asus Tinker Board specifications (bold highlights and strike-through show differences with MiQi board): SoC – Rockchip 3288 quad core ARM Cortex A17 up to 1.8 GHz with Mali-T764 GPU supporting OpenGL ES 1.1/2.0 /3.0, and OpenCL 1.1 System Memory – 2GB LPDDR3, dual channel Storage – 8 or 32 GB eMMC flash + micro SD slot Video output & Display I/F 1x HDMI 2.0 up to 3840×2160@60p […]

Ten Most Popular Posts of 2016 on CNX Software and Some Stats

The last day of the year is a good time to look back at what the year brought us, and I have to say it has been a fun and interesting year on CNX Software. The TV boxes news cycle has been dominated by Amlogic products, but most products have now switched to 64-bit ARM SoC, with 4K and HDMI 2.0 support, and price have kept going down, so you can now get a 4K TV box for as low as $20, although many people will prefer spending a bit more for extra memory and support. Intel based Bay Trail & Cherry Trail mini PCs have continued to be released with Windows, and in some cases Ubuntu, but the excitement seems to have died off a bit, maybe with the expectation of upcoming Apollo Lake mini PCs that should be more powerful. The year have been especially fruitful in the […]

SonikTech e-Paper Shield Starter Kit Relies on Teensy LC MCU Board

Soniktek Electronics has designed the “e-Paper Shield Starter Kit” featuring Pervasive Displays’ E2215CS062 e-paper screen, and an adapter board to connect it to Teensy LC (Low Cost) board powered by NXP Kinetis L ARM Cortex M0+ microcontroller @ 48 MHz, or other 3.3V MCU boards supporting SPI. Adapter board & display specifications: Supports Pervasive Displays 2.15″ E2215CS062 e-paper screen with 208 x 112 resolution, no backlight required, fully sunlight-readable Communication protocol – SPI @ 3.3V Sensor – On-board thermometer with I2C interface Dimensions – Screen: 48 mm x 26 mm; adapter board fits into Teensy-LC module (36x18mm) The advantages of e-Paper display are that they don’t require power to maintain an image, and they can be read in sunlight, just like actual paper. I can’t remember having seen many – if any – low cost e-Paper development kits so far, and the project is open source hardware with design files and […]

Android Things OS for the Internet of Things Supports Raspberry Pi 3, Intel Edison, and NXP Pico Boards

Google introduced Project Brillo a little over a year ago, an operating system based on Android, but with a smaller footprint optimized for Internet of Things applications. Brillo has now just become Android Things OS, with Google releasing a developer preview of Android Things working on Raspberry Pi 3, Intel Edison, and NXP Pico boards. The company has also updated the Weave platform to simplify connection of all types of devices to the cloud, and interaction with services like the Google Assistant. The Weave Device SDK currently supports schemas for light bulbs, smart plugs, switches, and thermostats, with more type of device supported in the future, as well as a mobile app API for both Android and iOS. Using an Android based OS instead of a pure Linux OS should make it easier for Android app developers to create smart devices thanks to the use of familiar Android APIs and […]

Linux 4.9 Release – Main Changes, ARM and MIPS Architectures

Linus Torvalds released Linux 4.9 on Sunday: So Linux 4.9 is out, and the merge window for 4.10 is thus open. With the extra week for 4.9, the timing for the merge window is obviously a bit awkward, and it technically closes in two weeks on Christmas Day. But that is a pure technicality, because I will certainly stop pulling on the 23rd at the latest, and if I get roped into Xmas food prep, even that date might be questionable. I could extend the merge window rather than cut it short, but I’m not going to. I suspect we all want a nice calm winter break, so if your stuff isn’t ready to be merged early, the solution is to just not merge it yet at all, and wait for 4.11. Just so you all know (I already bcc’d the main merge window suspects in a separate mailing last […]

Raspberry Pi 2 Gets an Upgrade to 64-Bit Broadcom BCM2837 Processor with PCB Version 1.2

With the launch of Raspberry Pi 3 based on Broadcom BCM2837 quad core Cortex A53 processor earlier this year, sales of Raspberry Pi 2 boards have suffering meaning the demand for Broadcom BCM2836 quad core Cortex A7 processor has also been reduced, and it appears the Raspberry Pi foundation has now launched Raspberry Pi 2 V1.2 with the faster BCM2837 processor. The new Raspberry Pi 2 v1.2 runs BCM2837 CPU cores up to 900 MHz, instead of 1.2 GHz on RPi 3, and includes 1 GB RAM. The main difference with Raspberry Pi 3 is the lack of the WiFi and Bluetooth module, which may also prevent some UART issues if you want to access the serial console or use an add-on board with UART. Since both boards cost the same ($35), most people should probably stick with Raspberry Pi 3, unless you’d rather not have any wireless module on […]
