LimeSDR Mini 2.0 USB SDR board gets an upgrade to Lattice Semi ECP5 FPGA (Crowdfunding)

The LimeSDR Mini is an open-source hardware full-duplex USB SDR board based on Intel Altera Max 10 Altera FGPA that was introduced in 2017 on Crowd Supply and raised close to $2 million US dollars. Since it has been used in various projects including digital TV transmitters. Lime Microsystems is now back on Crowd Supply with the similar-looking LimeSDR Mini 2.0 replacing the MAX 10 FPGA with 16K logic gates with a more powerful and capable Lattice Semiconductor ECP5 FPGA with 44K logic gates while keeping the company’s LMS7002 RF transceiver. LimeSDR Mini 2 specifications: FPGA – Lattice Semi ECP5 (LFE5U-45F) with 44K logic gates, 108 sysMEM blocks (18kb), 1,944 Kb embedded memory, 351 Kb distributed RAM bits Storage – 4 MB flash memory for data; 2x128KB EEPROM for RF transceiver MCU firmware and data RF Lime Microsystems LMS7002M RF transceiver Tx & Rx SMA connectors Frequency range – 10 […]

Turing Pi 2 mini-ITX cluster board supports RK3588 based Turing RK1, Raspberry Pi CM4, and NVIDIA Jetson SoMs (Crowdfunding)

We first covered the Turing Pi V2 mini-ITX cluster board supporting up to four Raspberry Pi CM4 or NVIDIA Jetson SO-DIMM system-on-module in August 2021. The company has now launched the Turing Pi 2 on Kickstarter with a little surprise: the Turing RK1 module with Rockchip RK3588 Cortex-A76/A55 processor and up to 32GB RAM. The board allows you to mix and match modules (e.g. 3x RPi CM4 + 1x Jetson module as on the photo below), and with SATA ports, Gigabit Ethernet networking, USB 3.0 ports, mPCIe socket, you could build a fairly powerful homelab, learn Kubernetes, or self-host your own apps. Turing Pi 2 specifications: SoM interface – 4x 260-pin SO-DIMM slots for up to four Raspberry Pi CM4 with Broadcom quad-core Cortex-A72 processor, up to 8GB RAM, up to 32GB eMMC flash (adapter needed) NVIDIA Jetson Nano/TX2 NX/Xavier NX SO-DIMM system-on-modules with up to 6x Armv8 cores, and […]

SkiffOS minimal Linux for embedded containers now supports Sipeed Nezha RISC-V board

SkiffOS minimal Cross-compiled Linux for embedded containers has just added support for Sipeed Nezha RISC-V single board computer, and work on the smaller Sipeed Lichee RV board has started. Wait… What is SkiffOS? I’ve never heard about it… That’s how the abstract from the white paper describes it: Embedded Linux processors are increasingly used for real-time computing tasks such as robotics and Internet of Things (IoT). These applications require robust and reproducible behavior from the host OS, commonly achieved through immutable firmware stored in read-only memory. SkiffOS addresses these requirements with a minimal cross-compiled GNU/Linux system optimized for hosting containerized distributions and applications, and a configuration layering system for the Buildroot embedded cross-compiler tool which automatically re-targets system configurations to any platform or device. This approach cleanly separates the hardware support from the applications. The host system and containers are independently upgraded and backed-up over-the-air (OTA). In other words, that’s […]

Amlogic T962E2 quad-core Cortex-A55 TV box board supports 4K HDMI input & output

Amlogic T962E2 is an upgrade to the Amlogic T962E quad-core Cortex-A53 SoC we first found in the Alfawise H96 Mini TV box with both HDMI output and HDMI input ports. The new processor offers similar features but comes with more efficient Cortex-A55 cores, a Mali-G31 MP2 supporting modern Vulkan and OpenGL ES 3.2 APIs, and some other improvements including 4K AV1 video playback. While mostly designed for Smart TVs, I found the Amlogic T962E processor in a TV box board with up to 4GB RAM, 32GB eMMC flash, HDMI 2.1 output, HDMI 2.1 input, Gigabit Ethernet, a wireless module, and allegedly running either Android 8, Android 9, or Android TV. TV box boards specifications: SoC – Amlogic T962E2 quad-core Arm Cortex-A55 processor @ up to 2.0 GHz with Arm Mali-G31 MP2 GPU support OpenGL ES 3.2, Vulkan 1.1 and OpenCL 2.0, 1.2 TOPS AI accelerator, 2x HiFi4 DSP System Memory […]
