Seeeduino Lotus Cortex-M0+ is a $10 Arduino compatible Board with 12 Grove Connectors

Grove modules are cool little add-on boards that connect through 4-pin header using UART, I2C, analog or digital I/Os, and usually you’d need to buy a HAT or shield to connect them to respectively Raspberry Pi or Arduino board. But Seeed Studio has come up with a small Arduino compatible board based on Microchip  SAMD21 microcontroller called Seeeduino Lotus Cortex-M0+ that may be the cheapest “Grove” solution around as it sells for just $9.90. Seeeduino Lotus Cortex-M0+ specifications: MCU – Microchip Atmel SAMD21 Arm Cortex-M0+ microcontroller at 48MHz with 256KB Flash and 32KB SRAM as found in Arduino Zero. USB – 1x micro USB port for power and programming Expansion 12x on-board Grove connectors (6x Digital, 3x Analog, 1x UART and 2x I2C) Arduino UNO headers 14x Digital I/O Pins (10 PWM outputs) 6x Analog Inputs I/O pins are 3.3V, do not input more than 3.3V, otherwise the CPU may […]

Systems-on-Module Market Update – An Interview with Toradex CMO

I’ve been interviewing Daniel Lang, Toradex Chief Marketing Officer (CMO), over email just before Embedded World 2019, to learn a bit more about the system-on-module market, and what’s ahead. CNXSoft: We’ve already covered several Toradex systems-on-module and development kits on CNX Software, but for readers who may not know Toradex yet, could you provide a short description of what the company does in the embedded systems space? Daniel Lang: Thanks for having me. Toradex builds high reliable Arm-based System on Modules. Our focus is to make the life of developers easier and to reduce the complexity and time-to-market. We sell hardware, but most of our engineering resources focus on Software and Support. Our products are used in areas such as Industrial Automation, Medical, Transportation, Test and Measurement, Building Automation and many more. CNXSoft: Could you explain why / what type of customers go the SoM route instead of designing for […]

Cost-Optimized Rock960 Model C Board Sells for $69 and Up

96Boards compliant Rock960 board launched last year for $99 with Rockchip RK3399 processor, 2 to 4GB RAM, 16 to 32GB eMMC flash for $99 and up. However, now you can buy a Rockchip RK3399 SBC for as low as $45 plus shipping thanks to FriendlyElec NanoPi NEO4 board that comes with 1GB RAM and no built-in storage, relying instead on a micro SD card slot or eMMC socket. So VAMRS decided to design a cheaper version of their board with Rock960 model C that still benefits from being part of the 96boards ecosystem, is equipped with 1, 2 or 4GB LPDDR4 RAM, and the OS can boot from a micro SD card or an optional eMMC flash module. The 1GB version of the board is now sold for $69 on Seeed Studio with shipping scheduled for the 1st of February 2019. Rock960 model C preliminary specifications: SoC – Rochchip RK3399 […]

FOSDEM 2019 Open Source Developers Meeting Schedule

FOSDEM – which stands for Free and Open Source Software Developers’ European Meeting – is a free-to-participate event where developers meet on the first week-end of February to discuss open source software & hardware projects. FOSDEM 2019 will take place on February 2 & 3, and the schedule has already been published with 671 speakers scheduled to speak in 711 events themselves sorted in 62 tracks. Like every year, I’ll create a virtual schedule based on some of the sessions most relevant to this blog in tracks such as  open hardware, open media, RISC-V, and hardware enablement tracks. February 2 10:30 – 10:55 – VkRunner: a Vulkan shader test tool by Neil Roberts A presentation of VkRunner which is a tool to help test the compiler in your Vulkan driver using simple high-level scripts. Perhaps the largest part of developing a modern graphics driver revolves around getting the compiler to […]

Giveaway Week – Libre Computer ROC-RK3328-CC Board

What will be the prize on the fourth day of this year’s giveaway week? Libre Computer ROC-RK3328-CC, a development board based on Rockchip RK3328 processor and mostly following Raspberry Pi 3 form factor. When I reviewed the board with Debian 9 last summer, I was mostly reminded how important fast storage and proper power supply were important. I had some kernel panic when using slow storage (micro SD card), but when I switch to the eMMC flash stability improved a lot. I also had some troubles with my USB 3.0 hard drive, but switching from a 5V/2A power supply to a 5V/2.5A power adapter solved most of my problems. Once I had “solved” those two issues the board worked fairly well, and Libre Computer always aims for mainline Linux support on their board, so that’s an advantage to take into consideration. The kit offered includes the board and heatsink, so […]

Linux 4.19 Release – Main Changes, Arm and MIPS Architectures

With Linus Torvalds taking a leave from the Linux kernel project, Greg Kroah-Hartman was the one to release Linux 4.19 last Sunday: Hi everyone! It’s been a long strange journey for this kernel release… While it was not the largest kernel release every by number of commits, it was larger than the last 3 releases, which is a non-trivial thing to do. After the original -rc1 bumps, things settled down on the code side and it looks like stuff came nicely together to make a solid kernel for everyone to use for a while. And given that this is going to be one of the “Long Term” kernels I end up maintaining for a few years, that’s good news for everyone. A small trickle of good bugfixes came in this week, showing that waiting an extra week was a wise choice. However odds are that linux-next is just bursting so […]

La Frite Amlogic S805X Board Runs Mainline Linux, Goes for $5 and Up (Crowdfunding)

Libre Computer first started with their AML-S905X-CC (aka Le Potato) board powered by Amlogic S905X processor last year, and they’ve since then launched several other boards based on Allwinner or Rockchip processor. But their latest “La Frite” board – also known as AML-S805X-AC – is an even lower cost version of the “Le Potato” board, with an Amlogic S805X processor limited to 1080p60 output and video decoding, a smaller footprint based on the one for Raspberry Pi Model A+, and price starting at just $5 on Kickstarter. AML-S805X-AC “La Frite” board specifications: SoC – Amlogic S805X quad core ARM Cortex-A53 processor @ 1.2 GHz with penta core ARM Mali-450MP GPU @ 650 MHz, and Amlogic Video Engine 10 System Memory – 512 MB or 1GB DDR4 @ 2400 MHz Storage –   eMMC module connector, 128 Mb SPI NOR flash Video & Audio Output – HDMI 2.0 port Video Codecs Decoding […]

RockPro64 RK3399 Board Linux Review with Ubuntu 18.04 + LXDE

Let’s do one more RK3399 Linux review using Pine64 RockPro64 development board. After shortly checking out the hardware, I’ll test Ubuntu 18.04 “Bionic” LXDE on the board, test 3D graphics acceleration, video playback, USB storage and network performance among other things on the board. RockPro64 Board Unboxing The board came in a cardboard package, and the sticker made it clear I had received the 2GB LPDDR4 version. Even after FriendlyELEC NanoPi M4 announcement, Rockchip ROCKPro64 is still the cheapest RK3399 development board around, so it should come as no surprise that the board does not come with any accessories by default. Another way to keep the price low was not to include any built-in storage apart from SPI flash, so instead most people will either boot from micro SD card or an eMMC flash module both of which need to be purchase separately. Another cost-saving is the lack of built-in […]
