Olimex RVPC is a one Euro RISC-V computer kit with VGA and PS/2 connectors

Olimex RVPC is one Euro RISC-V computer powered by a WCH CH32V003 RISC-V microcontroller and equipped with a VGA port for video output and a PS/2 connector to connect a keyboard. You won’t be able to do much with this device as an end-user, but it does not matter since the RVPC open-source hardware board mostly targets the education market and is offered as a kit to be soldered to lower the selling price and to serve as a soldering learning kit. Olimex RVPC specifications: MCU – WCH CH32V003 32-bit RISC-V2A microcontroller up to 48 MHz with 2KB SRAM, 16KB flash (SOP8 package with 6x GPIOs) Video Output – VGA connector (3x GPIO used for Vsync, HSync, and RGB) Keyboard port – PS/2 connector (2x GPIO used) Programmer port – 2-pin header for CH32V003 programming through a board such as ESP32-S2-DevKit-LiPo-USB Misc – Buzzer (1x GPIO) and Red power LED […]

ESP32-C6 WiFi 6 and Bluetooth 5.0 USB-C development board integrates 1.47-inch TFT LCD Display

Waveshare has introduced the ESP32-C6-LCD-1.47 development board powered by an ESP32-C6 RISC-V microcontroller with WiFi 6 and Bluetooth 5 connectivity and equipped with a 1.47-inch display with a 172×320 resolution. With a 4MB flash, an RGB LED, and a microSD card slot for extra storage, this board is suitable for projects that need a compact display, low power consumption, and wireless connectivity such as AIoT applications and human-machine interfaces (HMI). Earlier this month, we covered the ESP32-S3 USB dongle, another development board from Waveshare designed for HMI applications with the same 1.47-inch display with a 172×320 resolution, but a USB Type-A port instead of the USB-C port found in the model covered today. In the past, we’ve written about other ESP32-based development boards for HMI applications, including the LILYGO T-HMI, ESP32-S3-Touch-LCD-4.3B, and Waveshare’s ESP32-S3 LCD Driver Board supporting both square and round displays. Feel free to check them out if […]

Linux 6.11 Release – Notable changes, Arm, RISC-V and MIPS architectures

Linux 6.11 is out with Linus Torvalds’ announcement on the Linux kernel mailing list (LKML): I’m once again on the road and not in my normal timezone, but it’s Sunday afternoon here in Vienna, and 6.11 is out. The last week was actually pretty quiet and calm, which is nice to see. The shortlog is below for anybody who wants to look at the details, but it really isn’t very many patches, and the patches are all pretty small. Nothing in particular stands out – the biggest patch in here is for Hyper-V Confidential Computing documentation. Anyway, with this, the merge window will obviously open tomorrow, and I already have 40+ pull requests pending. That said, exactly _because_ I’m on the road, it will probably be a fairly slow start to the merge window, since not only am I on my laptop, there’s OSS Europe starting tomorrow and then the […]

LicheePi 3A – A SpacemIT K1 RISC-V development board with SoM and carrier board

Sipeed LicheePi 3A is a development board comprised of the LM3A system-on-module based on SpacemIT K1 octa-core RISC-V SoC and the same baseboard as found in the earlier LicheePi 4A equipped with a T-Head TH1520 quad-core RISC-V “LM4A” system-on-module instead. The LicheePi 3A is currently offered with a 32GB eMMC flash and 8GB or 16GB LPDDR4x memory. The carrier board provides a microSD card, two M.2 PCIe sockets for storage or other expansion, two gigabit Ethernet ports, a WiFi 6 and Bluetooth 5.2 module, HDMI and MIPI DSI display interfaces, two MIPI CSI camera interfaces, four USB 3.0 ports, and a 20-pin GPIO header for expansion. Sipeed LicheePi 3A specifications: Sipeed LM3A SoM SoC – SpacemiT K1 CPU – 8-core X60 RISC-V processor @ 1.6 GHz GPU – Imagination IMG BXE-2-32 with support for OpenGL ES3.2, Vulkan 1.2, OpenCL 3.0; 20 GFLOPS VPU – H.265 and H.264 1080p60 decoding/encoding NPU […]

DietPi 9.7 and Armbian 24.8 released with improved support for Rockchip, Amlogic, and Allwinner SBCs

Armbian and DietPi are two separate projects that provide Linux-based OS images optimized for Arm-based single board computers. The last time we had a look at both projects was in June with the release of Armbian 24.5.1 and DietPi 9.4, but there have been several updates since then including the releases of the latest DietPi 9.7 and Armbian 24.8 Yelt just a few days ago. So let’s check out the latest changes. DietPi 9.7 DietPi is a lightweight Debian-based Linux distribution for SBCs and server systems that ships as a minimal image but users can install any packages they want, including the ones required for desktop environment, to match the requirements of the applications. It’s notably used by the Linamp project – a Raspberry Pi 4-based project that brings WinAMP to real life – that we covered a few weeks ago. DietPi 9.7 was released on August 25, 2024 with […]

Using RISC-V cores on the Raspberry Pi Pico 2 board and RP2350 MCU – From blinking an LED to building Linux

Raspberry Pi Pico 2 RP2350 RISC-V review

Raspberry Pi Pico 2 was released last month with a Raspberry Pi RP2350 microcontroller equipped with two Arm Cortex-M33 cores and two 32-bit RISC-V “Hazard3” cores with up to two cores usable at any time. So in this guide, we’ll show how to use the RISC-V cores on the RP2350 MCU, compare their performance against the Arm Cortex-M33 cores, and even build Linux for RISC-V for RP2350 boards that have PSRAM. Apart from the extra memory and more powerful cores, plus new features related to security and the HSTX interface, the Raspberry Pi Pico 2 and Pico will be very similar to the end user and the instructions in our article “Getting Started with Raspberry Pi Pico using MicroPython and C” remain valid. I don’t think there’s a MicroPython RISC-V image yet, so we’ll focus on running C programs on the RISC-V cores. A quick check with the Arm cores […]
