qomu board

Qomu Cortex-M4F & FPGA USB board is programmable with Symbiflow open-source toolchain (Crowdfunding)

We’ve seen several tiny “omu” USB boards that are the size of a USB connector in the past, starting with Tomu based on Silabs EFM32 Arm-Cortex-M0+ MCU, then Fomu enabling Python programming and RISC-V softcore on a Lattice ICE40 FPGA, and finally Somu FIDO2 security key. There’s now the new Qomu board based on Quicklogic EOS S3 Cortex-M4F MCU with embedded FPGA. Just like its predecessor, the board almost completely fits in a USB connector except for the touch pads, and also happens to be programmable with Symbiflow that dubs itself as the “GCC of FPGAs”, as well as other open-source tools. Qomu specifications: SoC – QuickLogic EOS S3 Arm Cortex-M4F MCU @ up to 80 MHz with 512 KB memory, embedded FPGA with 2,400 effective logic cells and 64 Kbits of embedded RAM Storage – 16 Mbit flash Misc – Four capacitive touch pads, 1x RGB LED Power – […]

Raspberry Pi Pico Rust RT-Thread FreeRTOS

Raspberry Pi Pico Gets supports for Rust, RT-Thread OS and FreeRTOS

In January end, we saw the launch of Raspberry Pi Pico equipped with an RP2040 dual-core Cortex-M0+ microcontroller working up to 133 MHz with official support for MicroPython and C. In this feature, we will be discussing the Raspberry Pi Pico’s flexible software support compatible with RP2040 MCU, apart from the MicroPython, C/C++, and upcoming Arduino IDE software support. We will specifically be focusing on Rust, RT-Thread OS, and FreeRTOS support for Raspberry Pi Pico. Rust Code Running on Raspberry Pi Pico Rust language is considered fast, reliable, and secure when it comes to IoT gateways. It also opens up the option for writing extremely low-level code, such as operating system kernels or microcontroller applications.  Porting Rust with RP2040 for working with Raspberry Pi Pico was seen in Jonathan Pallant’s Twitter Feed. The RP2040 comes with an external QSPI flash. The internal mask-ROM reads the programs from the external flash […]

LoRa 2.4 GHz

LoRa 2.4GHz is now supported by The Things Network

Semtech brought LoRa to 2.4 GHz through their SX1280 & SX1281 transceivers to enable hardware manufacturers to design region-independent products, rather than region-specific products in the 433, 868, and 915 MHz bands a few years back. Things Industries announced support for LoRa 2.4GHz in The Things Network community network and its open-source stack at The Things Conference 2021 last week. However, switching to 2.4 GHz has a cost since range, one of the key selling points of LoRa, will be reduced compared to sub-GHz frequency, and that makes it most suitable for applications that work in different regions such as maritime and intercontinental logistics applications. Wilhelmsen has partnered with The Things Industries (TTI) and selected Semtech’s LoRa devices as the foundation for its new global 2.4GHz maritime IoT of the Seas platform to deliver an ecosystem of cost-effective, robust and proven IoT solutions and make them available to its diverse […]

really tiny USB-C boards

Some really tiny USB-C boards – MangoGeek dual serial USB board and Ant2 LiPo Charger

The most touted advantages of the USB Type-C port are that it is reversible, enables more reliable and faster charging, and extra features like DisplayPort alt mode. But it’s also about as small as the micro USB port, and yesterday I came across two really small board with a USB-C connector: Ant2 LiPo charger board and a TTL to USB debug board from MangoGeek with two serial ports. MangoGeek dual serial to USB board One the dual row header, with eight pins in total, is solder to the board, it’s about as big as a MicroSD card. The board is based on Silicon Labs CP2105 USB to dual UART bridge controller., and provides two Tx/Rx interfaces, DTR, RTS, 5V, and GND signals on the top and bottom of the board. One of the UART ports could be used to access a Linux serial, and the other to transmit data. The […]

Wiretrustee SATA board Raspberry Pi Compute Module 4

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

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 […]

Edge computing boards with new Intel Atom x6000E processors (Elkhart Lake) – Sponsored

A highly reliable performance boost for the edge The new Intel Atom® x6000E Series, Intel Celeron®, and Pentium® N & J processors (code name Elkhart Lake) impress with twice the graphics speed of their predecessors and 50% more multi-thread performance on up to 4 cores. congatec is now making these processors available on the 2.5-inch Pico-ITX form factor, leveraging their industrial quality for the most reliable performance boost possible. With growing digitization and the IoT trend, even the smallest edge computers are expected to meet high-reliability requirements today. Start-ups, makers, and spin-offs from big industrial companies increasingly deploy them in massively distributed applications to implement their new business models and IoT-supported services. They all face a similar challenge: Their apps are approaching market-readiness but their hardware platforms, which often originate from the maker board scene, lack reliability since they were not designed for large series and harsh environments. Industrial edge […]
