CloudBEAR BM-310 RISC-V MCU core for IoT applications

In the pool of 32-bit RISC-V microcontroller cores (E20 by SiFive, VEGA ET1031 by C-DAC), CloudBEAR showcased its 32-bit small and efficient MCU core – BM-310 at RISC-V GLOBAL FORUM 2020. CloudBEAR works on providing services like processor IP customization, support for RISC-V ISA extensions, product integration within a system-on-chip, and configurable instruction and data cache. Let’s first look into the CloudBEAR processor IP portfolio. It has three different product lines- BM series, BR series, and BI series. First, the BM series targets small and efficient MCUs cores. Second, the BR series targets fast and compact embedded cores. The third and most important BI series is about Linux capable application cores. In this article, we will look into the details of BM-310, which is the RISC-V MCU core for embedded and IoT solutions.  BM-310 Architecture As RISC-V is a modular instruction set, extensions are optional for the developer. BM-310 architecture (RV32IMCAFNB) includes many ISA extensions. It has RV32I as a […]

ODROID-HC4 low-cost dual NAS comes with 4GB RAM, supports 2.5-inch and 3.5-inch SATA drives

[Edit: Hardkernel has now updated their documentation to clarify the NAS uses ASM1061 PCIe to SATA controller instead of JMB582] It’s hard to find low-cost NAS platforms often because of the mechanism to insert drives and the enclosure add to the cost. An alternative is to use boards like Hardkernel ODROID-HC1 for 2.5-inch drives or ODROID-HC2 for 2.5- and 3.5-inch drives, but each board supports only one drive. The designs are stackable, but you’d need one Linux board per drive, so it’s not ideal. The Korean company has now launched a new model with ODROID-HC4 powered by an Amlogic S905X3 processor and shipping with a case supporting two 2.5-inch or 3.5-inch SATA drives that will start selling later this month for just $65 and up. ODROID-HC4 specifications: SoC – Amlogic S905X3 quad-core Cortex-A55 processor @ 1.8 GHz with Mali-G31 MP2 GPU System Memory – 4GB DDR4 Storage 128 Mbit SPI flash for bootloader like Petitboot UHS-1 compatible MicroSD card slot […]

Gumstix Introduces CM4 to CM3 Adapter, Carrier Boards for Raspberry Pi Compute Module 4

Raspberry Pi Trading has just launched 32 different models of Raspberry Pi CM4 and CM4Lite systems-on-module, as well as the “IO board” carrier board. But the company has also worked with third-parties, and Gumstix, an Altium company, has unveiled four different carrier boards for the Raspberry Pi Compute Module 4, as well as a convenient CM4 to CM3 adapter board that enables the use of Raspberry Pi CM4 on all/most carrier boards for the Compute Module 3/3+. Raspberry Pi CM4 Uprev & UprevAI CM3 adapter board Gumstix Raspberry Pi CM4 Uprev follows the Raspberry Pi Compute Module 3 form factor but includes two Hirose connectors for Computer Module 4. The signals are simply routed from the Hirose connectors to the 200-pin SODIMM edge connector used with CM3. Gumstix Raspberry Pi CM4 Uprev is the same except it adds a Google Coral accelerator module. Gumstix Raspberry Pi CM4 Development Board Specifications: 2x stacking board DF40-series connector for Raspberry Pi Compute Module […]

Raspberry Pi CM4 and CM4Lite Modules Launched for $25 and Up

We were expecting Raspberry Pi Compute Module 4 sometimes next year, but Raspberry Pi Trading Limited managed to launch the new module much earlier, as Raspberry Pi CM4 and CM4Lite modules have just been launched with a new, much more compact form factor incompatible with the earlier Compute Modules, an I/O board making use of the new features, and a choice of 32 models with variations in terms of memory and storage capacity, as well as the presence or lack thereof of a WiFi and Bluetooth wireless module. Raspberry Pi CM4 & CM4Lite Specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz with VideoCore VI GPU System Memory – 1, 2, 4, or 8GB LPDDR4-3200 SDRAM Storage – CM4: 4, 8, 16, or 32GB eMMC flash up to 100MB/s; CM4Lite: No storage device on module Networking Gigabit Ethernet transceiver Optional Wireless module with 802.11b/g/n/ac WiFi 5 and Bluetooth 5.0; external or PCB antenna (selectable by on-board electronic switch) […]

Intel Celeron 6305 and Pentium Gold 7505 Tiger Lake Processors Launched

Intel launched various Core i3/i5/i7 Tiger Lake processors in early September, shortly followed by more Core i3/i5/i7 UP3  Tiger Lake Embedded SoCs, so I was a little confused when Congatec launched a Tiger Lake COM Express module with of choice of processors including the usual Core processor plus an unnamed Celeron Tiger Lake processor because none were listed in Intel Ark. But a few weeks have passed, and there are now three new Celeron and Pentium Tiger Lake processors in the list namely: Pentium Gold 7505, Celeron 6305, and Celeron 6305E with the later optimized for embedded & IoT applications with a wider temperature range from 0 to 100°C. All three processors come with a 15W TDP and are manufactured using Intel’s 10nm process. As we can see from the table below both Celeron 6305 and Celeron 6305E have the exact same key features. The main difference between the Celeron and Pentium part is that the latter supports Hyperthreading and […]

NanoPi R2S & NanoPi NEO3 tested with Armbian – Thermal test, Ethernet and USB performance

In the first part of the review of NanoPi NEO3 and Nano R2S I checked out the hardware, with both tiny gateways powered by a Rockchip RK3328 processor but a different features as NEO3 includes a Gigabit Ethernet port and a USB 3.0 port, while R2S comes with dual Gigabit Ethernet ports and a USB 2.0 port. I’ve now had time to test both gateways using Armbian 20.08.1 release based on Ubuntu 20.04 Focal. Note that while NanoPi R2S is officially supported by Armbian, NanoPi NEO3 images are currently tagged as “suitable for testing“. Having that said I did not come across any specific issues on NEO3, and it may mostly mean it’s easier to get support on the forums with R2S. I flashed two microSD cards using USBImager with: Armbian_20.08.1_Nanopi-r2s_focal_current_5.8.6_minimal.img.xz Armbian_20.08.1_Nanopineo3_focal_current_5.8.6_minimal.img.xz That means Ubuntu 20.04 with Linux 5.8.6, but since Armbian is always updated, I ended the review with Linux 5.8.15. I’ll focus the review on thermal testing, as […]

Google Coral Dev Board mini SBC is now available for $100

Google Coral SBC was the first development board with Google Edge TPU. The AI accelerator was combined with an NXP i.MX 8M quad-core Arm Cortex-A53 processor and 1GB RAM to provide an all-in-all AI edge computing platform. It launched for $175, and now still retails for $160 which may not be affordable to students and hobbyists. Google announced a new model called Coral Dev Board Mini last January, and the good news is that the board is now available for pre-order for just under $100 on Seeed Studio with shipping scheduled to start by the end of the month. Coral Dev Board Mini specifications haven’t changed much since the original announcement, but we know a few more details: SoC – MediaTek MT8167S quad-core Arm Cortex-A35 processor @ 1.3 GHz with Imagination PowerVR GE8300 GPU AI/ML accelerator – Google Edge TPU coprocessor with up to 4 TOPS as part of Coral Accelerator Module System Memory – 2GB LPDDR3 RAM Storage – […]
