Embit EMB-LR1280-mPCIe-4x is a 2.4GHz LoRa mPCIe module based on Semtech SX1280 chipset

Embit EMB-LR1280-mPCIe-4x is an mPCIe (mini PCIe) module based on four Semtech SX1280 2.4 GHz LoRa transceivers and designed for OEM gateways that can work worldwide thanks to the use of the 2.4GHz ISM band and supports ranging. We first covered 2.4GHz LoRa and the SX1280 transceiver two years ago as a solution to design region-independent products specially suited to maritime and intercontinental logistics applications. We haven’t seen it used that much although we covered an ESP32 board with SX1280 last year, and it turns out that Italian company Embit has also made a mPCIe module based on the SX1280 chipset. Embit EMB-LR1280-mPCIe-4x specifications: LoRa connectivity Chipsets – 4x Semtech SX1280 transceiver with 3x LoRa Rx Channels + 1x LoRa Tx Modulation – LoRa Spread Spectrum Frequency – 2.4 GHz ISM band Frequency Range – 2400 to 2500 MHz RF Output power – Up to +12 dBm Sensitivity -129 dBm […]

$150 Axelera M.2 AI accelerator module claims to deliver up to 214 TOPS

Axelera M.2 AI accelerator module is said to deliver up to 214 TOPS of AI inference and up to 3200 FPS with ResNet -50 in a compact M.2 2280 form factor. Few details are available at this time, but the module is based on the company’s Metis AIPU (AI Processing Unit) using in-memory computing based on arrays of SRAM memory devices used to “store a matrix and perform matrix-vector multiplications “in-place” without intermediate movement of data”. This technology is said to “radically” increase the number of operations per computer cycle with without suffering from issues such as noise or lower accuracy. The Metis AI platform delivers 50+ TOPS per core (RISC-V-controlled dataflow engine), offers FP32 equivalent accuracy, and has a 15 TOPS/W energy efficiency. The last point is impressive, but that means 214 TOPS won’t be reachable with the module shown above, since the M.2 form factor is designed to […]

Credit card-sized COM-HPC Mini modules to support PCIe Gen4 and Gen5 interfaces

PICMG has announced that the COM-HPC Mini form factor’s pinout and dimensions definitions were finalized, with the tiny credit card-sized modules able to handle PCIe Gen4 and Gen5 interfaces, of course, depending on whether the selected CPU supports those. The COM-HPC “High-Performance Computing” form factor was created a few years ago due to the lack of interfaces on the COM Express form factor with “only” 440 pins and potential issues to handle PCIe Gen 4 clock speeds and throughputs. So far, we had COM-HPC Client Type modules from 95 x 120mm (Size A) to 160 x 120mm (Size C) and Server Type modules with either 160 x 160mm (Size D) or 200 x 160mm (Size E) dimensions. The COM-HPC Mini brings a smaller (95 x 70 mm) credit card-sized form factor to the COM-HPC standard. The way they cut the size of the COM-HPC Size A form factor by half […]

Intel Horse Creek platform showcased with SiFive P550 RISC-V CPU, 8GB DDR5, PCIe Gen5

When SiFive introduced its Performance P550 64-bit RISC-V processor in 2021, we were told that Intel would use it in the Horse Creek platform with “leading-edge interface IP such as DDR and PCIe” and manufactured with Intel’s 7nm process. We now have more details about the Horse Creek platform, as a development board was showcased for the first time in public at the Intel Innovation 2022 Developer Conference, and according to a report by Wikichip, the Cortex-A75 class quad-core RISC-V processor runs at up to 2.2 GHz, supports DDR5-5600 memory and eight PCIe 5.0 lanes, and was taped out with Intel 4 process. Horse Creek platform specifications: CPU – SiFive P500 quad-core RISC-V processor @ up to 2.2 GHz with a 13-stage, 3-issue, out-of-order (OoO) pipeline, private L2 cache, and common L3 cache Memory – DDR5-5600 interface PCIe – PCIe Gen5 through Intel’s PCIe PHY with 8 lanes, Synopsys PCIe […]

Radxa CM5 – A Rockchip RK3588S module (somewhat) compatible with Raspberry Pi CM4

Radxa has been working on the ROCK 5 Compute Module (aka Radxa CM5) system-on-module compatible with Raspberry Pi CM4, but based on the more powerful Rockchip RK3588S octa-core Cortex-A76/A55 SoC. Just like the Raspberry Pi Compute Module 4, it comes in a 55 x 40mm form factor, but instead of just two high-density 100-pin board-to-board connectors, the module includes three to cater for the additional I/Os from the Rockchip processor, just like they did for the Radxa CM3 equipped with a Rockchip RK3566 processor. Radxa CM5 specifications: SoC – Rockchip RK3588S octa-core processor with 4x Cortex‑A76 cores @ up to 2.4GHz, 4x Cortex‑A55 core @ 1.8GHz Arm Mali-G610 MP4 “Odin” GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, VP8 Video encoder – 8Kp30 H.265/H.264 video encoder 6 TOPS NPU System Memory – 4GB, 8GB, or 16GB LPDDR4x‑4224 SDRAM Storage – Optional 8GB, […]

USB4 Version 2.0 to enable speeds of up to 80 Gbps, introduce “active” USB cables

The USB Promoter Group has just pushed a press release about the “pending release” of the USB4 Version 2.0 specification that promises up to 80 Gbps of data performance over the USB Type-C cable and connector. The group also explains both the USB Type-C and USB Power Delivery (USB PD) specifications will also be updated, and everything will be published right before the USB DevDays developer events planned for November 2022 in the US and South Korea. So that’s basically an announcement about a future announcement, but we were still provided with some highlights of the upcoming USB4 v2 specification: Up to 80 Gbps operation based on a new physical layer architecture, using existing 40 Gbps USB Type-C passive cables and newly-defined 80 Gbps USB Type-C active cables. Updates to data and display protocols to better use the increase in available bandwidth. USB data architecture updates now enable USB 3.2 […]
