MutantC v3 open hardware DIY UMPC works with Raspberry Pi and compatible SBC’s

FOSDEM 2021 open-source developer event will take place online later this week, and yesterday we compiled a list of talks, with one entitled “MutantC PDA introduction – open source and hardware PDA shell” piquing my interest. The talk will be about the third revision of the hardware which allows you to create your own UMPC or handheld computer powered by a Raspberry Pi SBC or other compatible single board computers including Asus Tinker Board S, PINE H64 Model B, Banana Pi BPI-M4B, among others. MutantC v3 is versatile and highly customizable as can be seen from the specifications highlights: Supported SBCs – Raspberry Pi Zero, 2, 3, 4 and compatible. Arduino for keyboard – SparkFun Pro Micro 5v/16Mhz or SparkFun Qwiic Pro Micro – USB-C Display – 2.8-inch, 3.5-inch, or 4-inch “GPIO” LCD such as AdaFruit PiTFT 480×320 display Custom PCBs for display, mainboard, and thumbstick Expansion External 12-pin “docking” […]

FOSDEM 2021 Online February 6-7 – Hardware, Embedded & IoT talks

FOSDEM is an open-source developer event that takes place on the first week-end of February every year in Brussels, Belgium. Every year except this year, as due to COVID-19 restrictions, FOSDEM 2021 will take place online like most events these days. The schedule has been up for some time, and today I’ll look at some of the interesting talks mostly from the Embedded, Mobile and Automotive “virtual devroom” but also other tracks. Saturday, February 6, 2021 13:00 – 14:00 – From Reset Vector to Kernel – Navigating the ARM Matryoshka Long gone are the times of executing the OS in-place from memory-mapped flash upon reset. A modern SoC now comes with complex mask ROM firmware, with driver, filesystem, protocol and crypto support for loading… yet another bootloader. In his talk, Ahmad follows this chain of bootloaders until the kernel is started, stopping along the way for RAM setup, peripherial initialization, […]

Build a Raspberry Pi CM4 4-Bay NAS with Wiretrustee Carrier board

Wiretrustee SATA board Raspberry Pi Compute Module 4

Broadcom BCM2711 processor comes with a PCIe interface that is used for the USB ports on the Raspberry Pi 4 SBC, but that is exposed through the board-to-board connectors of Raspberry Pi Compute Module 4, aka Raspberry Pi CM4, and allows all sort of designs. So far we’ve mostly seen this PCIe interface used for M.2 expansion slots on devices ranging from industrial computers to carrier board such as Piunora or Gumstix Raspberry Pi CM4 development board. But Wiretrustee had a different idea and designed carrier board with Marvell 88SE9215 PCIe to SATA controller and offering four SATA connectors to build a 4-bay NAS with Raspberry Pi CM4 module. Wiretrustee carrier board specifications: Supported SoM – Raspberry Pi Compute Module 4 and 4 Lite Storage 4x SATA 2.0 via Marvell 88SE9215 (PCIe 2.0 x1 to 4 6Gb/s SATA ports, no HW RAID) chip tested at a write speed of ~220MB/s […]

SigmaStar SSD201/SSD202 powered 4G LTE industrial gateway made to run mainline Linux

SigmaStar SSD201 is a dual-core Cortex-A7 processor with 64MB RAM onchip that is designed for smart HD displays. We’ve previously seen it in Industio 7-inch smart display running Linux, but if you want to modify anything you’d need sign an NDA before getting the SDK. Luckily there’s an open-source community named linux-chenxing that aims to bring mainline support to those low-cost SigmaStar processor to mainline, the same way linux-sunxi is working on Allwinner processors. Daniel Palmer noticed MYZR recently launched GW300 4G LTE industrial gateway with specifications that looked familiar. GW300 specifications from manufacturer’s website: Processor – Arm Cortex-A7 dual-core processor @ 1.2GHz Memory – 64MB RAM Storage – 128MByte Flash Connectivity – Ethernet and 4G LTE with high-gain antenna Serial – RS485/ RS232 via 5-pin terminal block Misc – RTC Power Supply – 12V to 24V DC input Dimensions – 127.7 x 87.5 x 30 mm Temperature Range – […]

Hisense A7CC 5G smartphone integrates a 6.7-inch color E-Ink display

Hisense A5 was one of the first phones exclusively equipped with an e-Paper display. But following the launch of color E-Ink displays and color eReaders from other companies last year, the Chinese company has now launched Hisense A7CC 5G smartphone with a 6.7-inch color E-Ink display. The phone is powered by UNISOC T7510 octa-core processor, which appears to be based on T710 SoC with 5G modem, and comes with 6GB RAM and 128GB flash storage. Hisense A7CC specifications: SoC – UNISOC Tiger T7510 octa-core processor with 4x Arm Cortex-A75 cores @ 2 GHz, 4x Arm Cortex-A55 cores @ 1.8 GHz, and Imagination PowerVR GM9466 GPU System Memory – 6GB RAM Storage – 128GB flash Display – 6.7-inch E-Ink display with 4096 colors, 100 dpi Audio – 3.5mm headphone jack with AK4377AECB audio DAC; built-in microphone and speaker Camera – Dual rear cameras + single front-facing camera Connectivity Cellular – 5G […]

UniPi Gate RS485 Linux IoT Gateway features 600 MHz Rockchip RK3328 SoC

Based in the Czech Republic, UniPi Technology design and manufacture programmable logic controllers, gateways, sensors and systems for smart homes, building management systems, industry and automation projects. Their latest product is UniPi Gate G100/G110 Linux IoT gateway with Ethernet and RS485 interfaces. When the company contacted CNX Software about the gateway, they told us the system was based on a quad-core Cortex-A53 processor clocked at 600 MHz. Since we are not aware of such SoC, we asked, and UniPi told us it was Rockchip RK3328. That processor is normally clocked at 1.5 GHz, and it turns out the company purposely underclocked the processor to 600 MHz to extend the temperature range and reduce the heat emitted by the CPU. UniPi Gate G100 & G110 specifications: SoC – Rockchip RK3328 quad-core Cortex-A53 processor @ 600 MHz System Memory – 512MB RAM Storage – 16GB eMMC flash, MicroSD card slot Networking – […]
