WiFi 7 access point and client M.2 modules are cheaper than I thought

We have already seen WiFi 7 mini PCIe and M.2 modules from Compex for business customers, but I’ve recently noticed AsiaRF AW7991-AE2 M.2 module rated BE5000 offers an affordable alternative design for access points for just $58 plus shipping. But adding WiFi 7 to a consumer device can be cheaper than I expected as Intel BE200 or MediaTek MT7925-based M.2 modules can be purchased for around $20 to $30. Let’s have a look at some of the options available. AsiaRF AW7991-AE2 dual-band WiFi 7 “access point” M.2 module AsiaRF AW7991-AE2 specifications: SoC – MediaTek MT7991AV (Filogic 660?) with 32bit RISC-V MCU for Wi-Fi protocol and Wi-Fi offload Chipset – MT7976C WiFI 6 3×3 MIMO chipset System Memory – 8MB WLAN IEEE 802.11a/b/g/n/ac/ax/be compliant Frequency bands 2.4GHz – Bandwidth: 20/40MHz; 2T2R 2ss 5GHz – Bandwidth:20/40/80/160MHz; T3R 3ss Dual-Band Dual Concurrent (DBDC) Supports up to 4096-QAM Data rate of up to 688Mbps […]

Firefly’s CSB1-N10 series AI cluster servers can deliver up to 1000 TOPS of AI power with Rockchip or NVIDIA Jetson Modules

Firefly has recently introduced the CSB1-N10 series AI cluster servers designed for applications such as natural language processing, robotics, and image generation. These 1U rack-mounted servers are ideal for data centers, private servers, and edge deployments. The servers have multiple computing nodes, featuring either energy-efficient processors (Rockchip RK3588, RK3576, or SOPHON BM1688) or high-performance NVIDIA Jetson modules (Orin Nano, Orin NX). With 60 to 1000 TOPS AI power, the CSB1-N10 servers can handle the demands of large AI models, including language models like Gemma-2B and Llama3, as well as visual models like EfficientVIT and Stable Diffusion. CSB1-N10 series specifications All CSB1-N10 AI servers have the same interfaces, and the only differences are the CPU, memory, storage, multimedia, AI capabilities, and related software support. So it’s likely Firefly has made Rockchip system-on-modules compatible with NVIDIA Jetson SO-DIMM form factor, and indeed we previously noted that Firefly designed Core-1688JD4, Core-3576JD4, or Core-3588JD4 […]

Luckfox Lyra boards feature Rockchip RK3506G2 triple-core SoC, display interface, optional Ethernet port

Luckfox Lyra RK3506G2 RJ45 display interface

The Luckfox Lyra boards feature a Rockchip RK3506G2 triple-core Arm Cortex-A7 SoC with one Cortex-M0 real-time core, 128MB on-chip DDR3, a MIPI DSI display interface, and built on a 22nm process. Three versions are available with the Luckfox Lyra, Lyra B (with 256MB flash), and Luckfox Lyra Plus offering similar features, but the longer Plus model also adds a 10/100Mbps Ethernet RJ45 connector besides having 256MB SPI NAND flash. These are Luckfox’s first boards featuring the RK3506G2 processor, offering Ethernet connectivity and a display interface. But it’s not quite the first Arm Linux board from the company with Ethernet and a display interface, and we covered the Luckfox Pico Ultra micro development board all based on a Rockchip RV1106G3 SoC earlier this year. The company also introduced the similar-looking LuckFox Pico Pro and Pico Max boards powered by an RV1006G2 SoC in February, but instead of a display interface, they […]
