Giveaway Week 2023 – WCH CH583M-R0 development board and some RISC-V microcontrollers

Early this year, WCH sent me a few of their RISC-V MCU boards and chips to thank me for writing about their products. I gave one for review with some chips but it went to review heaven, or in other words, no review was ever written. I also sold a couple locally, and since I don’t think I’ll ever have time for a review, we are now giving away the remaining boards and chips here and on CNX Software Thailand. Today’s giveaway is the WCH CH583M-R0-1v1 board, also known as CH583EVT or CH583M-EVT-R0, based on the CH583 RISC-V Bluetooth 5.3 LE microcontroller that exposes all I/Os from the chip, a few buttons, and USB ports, and also features an SWD/UART header for debugging. You’ll find the documentation, code samples, an Android app and other resources to get started on GitHub. I’ll also throw all the remaining chips I have left […]

Firefly ROC-RK3588-RT Rockchip RK3588(J) SBC comes with three 2.5Gbps/gigabit Ethernet ports

Firefly ROC-RK3588-RT is a Rockchip RK3588(J) SBC suitable for networking applications such as routers and firewalls thanks to one 2.5GbE port and two gigabit Ethernet ports and available in both commercial and industrial temperature grades. But the board is likely to be used for more complex workloads since it also comes with three video output interfaces (2x HDMI and USB-C DisplayPort), M.2 sockets for a SATA or NVMe SSD, a WiFi 6/Bluetooth 5.2 module, a 6 TOPS NPU embedded in the Rockchip processor, and a (non-standard) expansion connector with PCIe Gen 3 and other interfaces. Firefly ROC-RK3588-RT specifications: SoC (one or the other) Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76 cores @ up to 2.4 GHz, 4x Cortex‑A55 core @ 1.8 GHz GPU – Arm Mali-G610 MP4 “Odin” GPU @ 1.0 GHz Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, VP8 […]

Giveaway Week 2023 – GL.iNet GL-S200 Thread Border Router devkit

Getting Started GL-S200 Thread Border Router

It’s already day 4 of CNX Software Giveaway Week 2023 and today, we’ll be giving away GL.iNet GL-S200 Thread Border router kit that also includes three USB or battery-powered Thread development boards to experiment with various Thread topologies. The GL-S200 router comes with a Qualcomm QCA9531 MIPS router processor running a fork of OpenWrt and provides two Fast Ethernet WAN/LAN ports, 2.4 GHz Wi-Fi 4 802.11b/g/n up to 150 Mbps, and support for Thread (via an 802.15.4 radio) and Bluetooth 5.0. The development boards are based on the Nordic Semi nRF52840 microcontroller and each features a potentiometer+button, a PIR sensor, and two RGB LEDs. I reviewed the GL-S200 Thread Border router kit using the router’s dashboard interface and demo firmware provided for the three development boards. This enabled me to test star topology and mesh networking, and play around with demo scripts and code samples to display sensor and potentiometer […]

MeLE Overclock4C is an ultrathin pocket-sized mini PC powered by an Intel Processor N95 CPU

Mele Overclock4C is an Intel Processor N95 Alder Lake-N mini PC with an ultrathin (21mm) design which, as its name implies, supports “overclocking”, although what it really means here is the ability to increase the PL1 and PL2 power limits in the BIOS/UEFI in order to increase performance without actually changing the top frequency of the processor… It’s the same idea and virtually the same design as the MeLE Overclock3C which boosts the TDP of the Celeron N5095 Jasper Lake processor up to 18W instead of the 15W default. Here the TDP of the Processor N95 is likely boosted up to 20 Watts (as per Intel Ark) delivering a 33% performance improvement over the Celeron N5095. The Overclock4C is available with 16GB or 32GB DDR4, a 256GB eMMC flash, and a 256GB SSD. MeLE Overclock4C specifications: SoC – Intel Processor N95 quad-core Alder Lake N-series processor @ up to 3.4 […]
