6.67-inch flexible AMOLED display works with Raspberry Pi, LattePanda, and other SBCs with HDMI output

DFRobot has introduced a 6.67-inch flexible AMOLED display with a 2400×1080 resolution, designed for easy use with single-board computers such as Raspberry Pi and LattePanda. While flexible displays are common in smartphones, they are difficult to interface with SBCs, so DFRobot added a dedicated MIPI-to-HDMI driver board for plug-and-play compatibility with a wider range of platforms. The panel is just 1.2mm thick and bendable, enabling curved and space-constrained designs, while delivering 450 cd/m² brightness and 16.7 million colors. Like typical OLEDs, it offers deep blacks and high contrast without requiring a backlight, making it suitable for applications ranging from wearables and robotics to industrial HMI systems. DFRobot 6.67” flexible AMOLED Display specifications: Compatibility – Raspberry Pi, Banana Pi, Orange Pi, and most devices with an HDMI output. Display Panel Screen Size – 6.67 inches Screen Material – Flexible AMOLED Resolution – 2400 x 1080 (SPR – Sub-Pixel Rendering) Aspect Ratio […]

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

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 […]

HAUI 3Gang Touch Display is a 7-inch wall-mount Home Assistant dashboard with MQTT support

HAUI 3Gang 7-inch Display Wall Mount Dashboard WiFi

The HAUI 3Gang Touch Display is a wall-mount smart home control dashboard designed specifically to run Home Assistant, OpenHAB, Domoticz, or any other web-based home automation dashboard. Built around a Raspberry Pi 3B+ since it’s one of the cheapest options following Pi 4/5 price hikes, the HAUI (Home Assistant User Interface) replaces standard wall switches and fits into a standard single-gang electrical box, while its front panel spans roughly a three-gang footprint, hence the “3Gang” name. It runs a customized version of FullpageOS Linux distribution with a Chromium browser in kiosk mode and includes built-in MQTT integration along with SSH access for advanced users. HAUI Touch Display specifications Main Controller – Raspberry Pi 3B+ Display – 7-inch capacitive touchscreen Connectivity – Wi-Fi on Raspberry Pi (configured via initial setup wizard) Power Input Voltage – 120 VAC ±10% Maximum Current – 1 A Internal USB charger module (Line/Neutral wiring, no ground […]

ESP32-P4 security key features 2-inch touchscreen, 3,000+ password capacity (Crowdfunding)

MiixKey compact offline hardware security key and password manager

MiixKey is a compact, offline ESP32-P4-based hardware security key and password manager that securely stores passwords, passkeys, NFC cards, and smart card credentials in a single portable device. It features a 2-inch touchscreen and is designed for users, developers, enterprises, government staff, and cybersecurity professionals who need secure offline credential management without relying on cloud services or smartphone apps. Previously, we wrote about security keys like the YubiKey and Google Titan Security Key, which are great for FIDO2 and U2F login, but they don’t have a display or user interface, so managing passwords or switching credentials usually requires a phone or computer. MiixKey fixes this by adding a touchscreen and allowing the user to manage over 3,000 passwords fully offline. MiixKey specifications: Main SoC – Espressif Systems ESP32-P4 CPU Dual-core 32-bit RISC-V HP (High-performance) CPU @ up to 400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to […]

Boardcon PICOT536 SoM and EMT536 SBC feature Allwinner T536 Edge AI processor

Back in April last year, Allwinner released the T536 SoC, and since then, we’ve seen MYiR Tech and Forlinx introduce SoM and SBC based on it. The latest to join the lineup is Boardcon, which has recently launched the PICOT536 SoM and EMT536 SBC for industrial HMI, machine vision, robotics, and other edge computing applications. As a reminder, the Allwinner T536 SoC features a quad-core Arm Cortex-A55 CPU, XuanTie E907 and E902 RISC-V coprocessors, and a 2 TOPS NPU for edge AI. The module comes with up to 8GB LPDDR4/LPDDR4X memory, up to 64GB eMMC flash, an optional WiFi 6 and Bluetooth 5.4 module, and a 314-pin MXM edge connector exposing I/Os such as MIPI DSI and LVDS, camera inputs, audio inputs and outputs, Gigabit Ethernet, PCIe, USB 3.0, and more. PICOT536 System-on-Module PICOT536 specifications: SoC – Allwinner T536 CPU – Quad-core Arm Cortex-A55 at up to 1.6GHz, RISC-V XuanTie […]

AMD Versal Prime VM2152 mid-range adaptive SoC features 112 Gbps GTM Transceivers, 600Gbps Ethernet, DDR5/LPDDR5

The AMD Versal Prime VM2152 adaptive SoC is designed as a mid-range device for high-speed connectivity, with 112 Gbps transceivers and 600 GbE networking in a power-efficient package. It balances programmable logic with hardened IP blocks to simplify the design of high-throughput systems used in wired communications, aerospace, and test and measurement, without the higher power and complexity of high-end FPGAs. Compared to the AMD Versal Prime VP1902, the VM2152 focuses more on I/O performance rather than raw logic density. While the VP1902 offers more logic cells, the VM2152 adds support for LPDDR5 memory up to 6400 Mb/s and includes a 400 Gbps High-Speed Crypto engine, making it suitable for faster, more secure data processing than Agilex 7.
