Mind xPlay display and keyboard review using Khadas Mind and Mind 2 mini PCs

Khadas xPlay connected to Crowview USB C display

In this review, I’ll report my experience with the Khadas Mind xPlay display and keyboard using the Mind and Mind 2 mini PCs, as well as a CHUWI CoreBook Air Plus 16 laptop to test it as a standard external display. Using Mind xPlay with the Mind 2 mini PC I received the Mind xPlay with the Mind 2 Meteor Lake mini PC, and I already showed how to connect it and get started in the first part of the review. So I’ll continue the review with it initially. I used the EIZO monitor test website to evaluate the display panel itself. I went through all 13 tests, including dead pixel and gradients tests. The pattern above looks fine too, so I compare the Mind xPlay monitor to the 16-inch display of the ASUS Vivobook 16 to find differences. Both were set to maximum brightness. The xPlay delivers noticeably more […]

Up to 256 MB FERRIT modular F-RAM storage device preserves critical data for up to 200 years

FERRIT F-RAM storage

Machdyne’s FERRIT is a modular USB F-RAM storage device with a capacity of up to 256 MB and capable of storing data for up to 200 years with a virtually unlimited number of writes and high-radiation resistance. It builds upon the earlier Blaustahl F-RAM storage device that only offers 8KB capacity. The FERRIT device supports 8 MB to 256 MB by combining up to 256 individual 1 MB F-RAM ICs. The prototype below is housed in a metal frame and looks like a typical cluster solution. FERRIT specifications and key features: FERRIT-CY controller based on Raspberry Pi RP2040 MCU with USB-FS Type-C port FERRIT-M8 removable ferroelectric memory cards with up to 16MB capacity using 16x 1MB F-RAM ICs (double-sided: 2x 8 chips) FERRIT-16 backplane with slots for FERRIT-CY and 16x FERRIT-M8 connected over SPI/QSPI bus Max capacity – 256 MB+ through up to 256x memory devices (16 memory cards with 16 chips) […]

Khadas Mind Graphics 2 and Mind xPlay display + keyboard review – Part 1: Unboxing, teardown, and first try

Khadas Mind 2 Graphics xPlay Review

Khadas has sent us the Mind Graphics 2 dock, Mind xPlay portable display and keyboard, as well as the Mind 2 mini PC for review. In the first part of the review, I’ll start by listing specifications, an unboxing of all three packages, a teardown of the graphics dock, and a first try of the xPlay and Mind Graphics 2 with the mini PC. While the Mind 2 will be used for testing, I won’t go into details here since it’s quite similar to the Mind 2 AI Maker Kit we reviewed last year. Instead, in the next parts, I’ll do a review of the xPlay with it, the first-generation Mind, and maybe another platform with USB-C video output. I’ll follow that by detailed testing of the Khadas Mind 2, including graphics and AI performance with the built-in NVIDIA GeForce RTX 5060 Ti 16GB card, and check all its features. […]

FalCAN Probe is an open-source, STM32-based USB to CAN/RS-485/RS-422 adapter

FalCAN Probe v0

Most USB-to-bus adapters, including tools like CANTact Pro or MeatPi’s Ollie V1 and V2, typically support either CAN or RS-485/RS-422 as fixed-function serial devices. In contrast, the FalCAN Probe by Anders B. Nielsen is a multi-protocol USB adapter based on the STM32F042 microcontroller. The FalCAN Probe is a compact open-source USB Type-C board that connects a computer to CAN, RS-485, and full-duplex RS-422 networks. Instead of using a fixed USB bridge, it exposes the MCU’s native USB interface along with SWD and GPIOs, and can also be used as a small Arm Cortex-M0 development platform. FalCAN Probe specifications: MCU – STMicro STM32F042C6Tx Arm Cortex-M0 microcontroller @ 48 MHz with 32KB flash, 6KB SRAM Host Interface – USB 2.0 Full Speed via USB Type-C port Interfaces (non-isolated) CAN bus via Texas Instruments SN65HVD230 transceiver; enumerates as a GS_USB CAN device when jumper JP4 is open RS485 and full-duplex RS422 via dual […]

Realtek RTL8159 10GbE to USB 3.2 adapters sell for about $55 and up

WisdPi WP-UT9 10GbE USB 3.2 adapter

Realtek unveiled low-cost, low-power 10GbE RTL8127 (PCIe) and RTL8159 (USB 3.0) controllers at Computex 2025. Since then, we noted that RTL8127-based M.2 and PCIe 10GbE cards had already launched for as low as $35. However, a new X post by Jeff Geerling reminded me it was time to check on those RTL8159 10GbE to USB 3.2 adapters. So let’s do that now, starting with the Wisdpi WP-UT9 mentioned in the post/tweet. Wisdpi WP-UT9 WisdPi WP-UT9 specifications: Chipset – Realtek RTL8159 Ethernet – Up to 10GbE RJ45 port; backward compatible with 5 Gpbs, 2.5 Gbps, 1Gbps, and 10/100Mbps Ethernet USB – USB 3.2 Gen2 Type-C port; backward compatible, but slower ports will impact performance; USB hubs/docks and long cables are not recommended either Misc – 2x LEDs – Amber (Link) / Green (Activity) Power Supply – Via USB-C port Dimensions – 59 x 29 x 13 mm Weight – 58.8 grams […]

Nuvoton NuMicro M3331 Cortex-M33 MCU features built-in ARGB LED controller, optional USB 2.0 OTG interface

M3333 Series MCU

Nuvoton’s new NuMicro M3331 is a series of 32-bit Arm Cortex-M33 MCUs clocked at 180 MHz that integrate an ARGB LED controller, a DSP instruction set, a single-precision FPU, and TrustZone security for smart factories, renewable energy systems, and consumer devices. In the past, we have written about other Cortex-M33 MCUs like the STM32U3B5/C5, Texas Instruments MSPM33C321A,  Nordic Semi’s nRF54LM20A, and various others, but the Nuvoton M3331 series specifically features a built-in Enhanced LED Light Strip Interface (ELLSI) and up to 10 standard LLSI channels. This allows the MCU to natively support gaming ARGB Gen1 and Gen2 LED control protocols, completely offloading the CPU to run fluid, dynamic LED effects. It comes in two variants, the M3333 series and the M3334 series, with the latter adding a high-speed USB 2.0 OTG controller with an integrated PHY. NuMicro M3331 specifications: MCU core – Arm Cortex-M33 32-bit CPU @ 180 MHz with single-precision […]
