Radxa Zero 3E SBC offers gigabit Ethernet and PoE in Raspberry Pi Zero 2 W form factor

Radxa Zero 3E

Last December, we wrote about the Rockchip RK3566-powered Radxa Zero 3W WiFi 6 SBC and noted that the Radxa Zero 3E with gigabit Ethernet and optional PoE supports would be coming soon with about the same dimensions as the Raspberry Pi Zero 2 W. “Soon” is now as the Radxa Zero 3E is now available on Aliexpress or Amazon with RAM capacities from 1GB to 8GB LPDDR4. The small SBC also comes with optional eMMC flash up to 64GB, a microSD card slot for storage, a micro HDMI video output port, a MIPI CSI connector compatible with Raspberry Pi Camera V1 and V2, two USB-C ports, and a 40-pin GPIO header for expansion. Radxa Zero 3E specifications: SoC – Rockchip RK3566 CPU – Quad-core Arm Cortex-A55 processor @ 1.6 GHz GPU – Arm Mali G52-2EE GPU with support for OpenGL ES 1.1/2.0/3.2, Vulkan 1.1, OpenCL 2.0 NPU – 0.8 TOPS […]

Waveshare Thermal Imaging Camera Module – Raspberry Pi HAT or USB-C model, 80×62 resolution, dual FOV options (45°/90°)

Waveshare Thermal-90 USB and Thermal-90 Camera HAT

The Waveshare Thermal Imaging Camera module comes in two variants, namely the Thermal-45/90 Camera Raspberry Pi HAT and Thermal-45/90 USB Camera. The main difference between the two is that the HAT is designed to be attached to a Raspberry Pi, Pi Zero, or any other SBC that features a Pi-compatible pin layout like the Sipeed Longan Pi3H, Banana Pi BPI-M4, Radxa Zero 3W SBC, and others. On the other hand, the USB module can be connected to any PC, Android, or other device with a USB connection. The camera features a shutterless design, which is why it can produce a thermal imaging video stream output of up to 25 frames per second (FPS). Additionally, Waveshare offers options for different fields of view (FOV) – a basic version with a 45° FOV and a wide-angle version with a 90° FOV, making it suitable for applications like IR thermometers, industrial temperature control, […]

Maker Uno RP2040 review with Arduino IDE using micro servo, soil moisture sensor, ultrasonic sensor, and I2C OLED modules

Maker Uno RP2040 review Arduino IDE

Today, We will review the Cytron Maker Uno RP2040 development board combining the Arduino UNO form factor with the Raspberry Pi RP2040 microcontroller that makes it programmable with the Arduino IDE (C/C++), Micropython, or CircuitPython. The board is suitable for both beginners and advanced users with a convenient port layout that includes a “Maker” connector plus six Grove connectors for sensor modules and a header for four servos besides the Arduino UNO headers. The board offers two power options: USB (5V) via the USB-C connector or a single-cell LiPo/Li-Ion battery via the LiPo connector. Cytron Maker Uno RP2040 specifications SoC – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ processor @ up to 133 MHz with 264 KB SRAM Storage – 2MB flash USB – USB-C port for power and programming Expansion Arduino UNO headers for shields 6x Grove Ports (Digital I/O, PWM Output, UART, I2C, Analog Input) 1x Maker port compatible […]

XGO-Rider is a 2-wheel self-balancing robot with an ESP32 controller plus either a Raspberry Pi CM4 or BBC Micro:bit (Crowdfunding)

XGO-Rider

XGO-Rider is a two-wheel self-balancing robot with an ESP32 controller for motor and servo control, USB-C charging, etc… and a choice between a Raspberry Pi CM4 module or a BBC Micro:bit board for display, audio, and camera (CM4-only). It’s not the first robot from Luwu Intelligence, since the company launched the XGO-Mini robot dog in 2021, followed by the XGO 2 Raspberry Pi CM4-powered desktop robotic dog with an arm which we reviewed last year. The new XGO-Rider builds on these earlier models but in a different form factor moving from four-legged robots to a 2-wheel self-balancing robot design with many of the same features including AI vision running on the Raspberry Pi CM4. XGO-Rider specifications: Host controller (one or the other) Raspberry Pi CM4 with 2GB RAM + ESP32 for main control, USB-C charging port, DIP switch BBC Micro:bit V2 + ESP32 for main control, USB-C charging port, DIP […]

QEMU 9.0 released with Raspberry Pi 4 support and LoongArch KVM acceleration

QEMU 9.0

QEMU 9.0 open-source emulator just came out the other day, and it brings on board major updates and improvements to Arm, RISC-V, HPPA, LoongArch, and s390x emulation. But the most notable updates are in Arm and LoongArch emulation. The QEMU 9.0 emulator now supports the Raspberry Pi 4 Model B, meaning you can run the 64-bit Raspberry Pi OS for testing applications without owning the hardware. However, QEMU 9.0 has some limitations since Ethernet and PCIe are not supported for the Raspberry Pi board. According to the developers, these features will come on board in a future release. For now, the emulator supports SPI and I2C (BSC) controllers. Still on ARM, QEMU 9.0 provides board support for the mp3-an536 (MPS3 dev board + AN536 firmware) and B-L475E-IOT01A IoT node, plus architectural feature support for Nested Virtualization, Enhanced Counter Virtualization, and Enhanced Nested Virtualization. If you develop applications for the LoongArch […]

Openterface Mini-KVM is an affordable KVM-over-USB device (Crowdfunding)

Openinterface Mini-KVM

Openterface Mini-KVM compact, open-source hardware KVM-over-USB device with HDMI and audio inputs which connects over a USB-C port to the host computer. We’ve seen quite a few low-cost KVM-over-IP solutions based on single board computers over the years, but the Openterface Mini-KVM is quite different (and cheaper) as a plug-and-play and network-independent KVM-over-USB device that establishes a direct HDMI and USB connection between the host computer and the target device. It supports many of the same features as KVM-over-IP solutions except for some features such as ATX support found in the PiKVM v4 Plus or the Pi-Cast KVM with an expansion board that allows the target device to be turned off and from the host device. Mini-KVM (model LIG03D01) specifications: Control method – KVM-over-USB Video capture – Up to 1920×1080 @ 30 Hz with under 140ms latency through HDMI or VGA (the latter requires an add-on VGA-to-HDMI cable) Audio capture […]

Raspberry Pi Connect software makes remote access to Raspberry Pi boards easier

Raspberry Pi Connect

Raspberry Pi Connect software, currently in beta, aims to make remote access to the Raspberry Pi boards even easier and more secure by using a web browser and minimal configuration needed. It’s been possible to access Raspberry Pi boards remotely through VNC forever, and the X protocol used to be an option before the switch to Wayland, but both can be somewhat hard to configure especially when wanting to access the machine on a different local network or from the internet. Raspberry Pi Connect aims to change that. Under the hood, we’re told the web browser and the Raspberry Pi device established a secure peer-to-peer connection with the same WebRTC communication technology found in programs such as Zoom, Google Meet, or Microsoft Teams. The Raspberry Pi runs the “rpi-connect” daemon that listens to screen-sharing requests from the Raspberry Pi Connect website and establishes a secure, low-latency VNC instance directly between […]

$23 C790 HDMI to MIPI CSI adapter adds HDMI and audio input to Raspberry Pi SBCs

Raspberry Pi 4 HDMI Input board

C790 is an HDMI to MIPI CSI-2 board compatible with Raspberry Pi single board computers featuring a 40-pin GPIO header that adds both HDMI input up to 1080p60 and I2S audio input to the popular Arm SBC. The solution can be useful for IP KVM solutions as we’ve seen with the PiKVM v3 and PiCast portable KVM switch, or to capture video and audio from a camera that outputs HDMI with audio through the board’s MIPI CSI camera interface and I2S input signals on the GPIO header. C790 specifications: Supported SBC’s – Raspberry Pi Zero, 3B, 3B+, 4B, CM3, CM4 with MIPI CSI-2 input port (Note: Raspberry Pi 4 is limited to 1080p50 due to 2-lane MIPI CSI-2, CM4 supports 1080p60) Main chip – Toshiba TC358743XBG HDMI to CSI-2 bridge chip up to 1920×1080, 60 FPS Video and audio input – HDMI port up to 1080p60 Video Output – 2-lane […]
