Waveshare ESP32-P4-ETH development board supports Ethernet and PoE

Waveshare ESP32 P4 ETH Edge AI dev baord with ESP32 P4 and Ethernet

Waveshare ESP32-P4-ETH is a compact ESP32-P4 development board with Ethernet and PoE support, which looks very similar to the Olimex ESP32-P4-DevKit minus the pUEXT connector. However, we’ve also covered other ESP32-P4 boards with Ethernet (and other features) such as the ESP32-P4-Module-DEV-KIT, the ESP32-P4-NANO board, and the GUITION JC-ESP32P4-M3-DEV. Design wise, the board also looks very similar to the Wiznet boards based on Raspberry Pi RP2xxx microcontroller such as the W55RP20-EVB-Pico, the W6300-EVB-Pico2, and the W5100S-EVB-Pico2 boards, but you can also run multimedia workloads with MIPI camera and display interfaces, hardware video encoding, audio processing, AI speech functions, and advanced security features on the ESP32-P4-ETH board. Waveshare ESP32-P4-ETH specifications: 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 40 MHz Memory 768 KB HP L2MEM (for dual-core CPU), 32 […]

Debian 13 “Trixie” released with Linux 6.12, official 64-bit RISC-V support

Debian 13 “Trixie” has just been released with Linux 6.12 LTS, GNOME 48 desktop environment (default), GCC 14.2 compiler, and over 14100 new packages for a total of 69830 packages. This follows the Debian 12 Bookworm release in June 2023 with Linux 6.1. While we had previously tested Debian 12 on RISC-V, Debian 13 is the first release that officially supports 64-bit RISC-V. Debian 13 will serve as the base for Ubuntu, Raspberry Pi OS, and many other Linux distributions. Other Debian 13 highlights: Hardening against Return-Oriented Programming (ROP) exploits and Call/Jump-Oriented Programming (COP/JOP) attacks on amd64 and arm64 targets. HTTP Boot Support – The Debian Installer and Debian Live Images can now be booted using “HTTP Boot” on supported UEFI and U-Boot firmware. Improved manual pages translations (especially Romanian and Polish) BDIC Binary Hunspell Dictionary Support Spell-checking support in Qt WebEngine web browsers (Privacy Browser and Falkon); implemented through BDIC […]

Sipeed NanoCluster palm-sized cluster board takes up to 7 system-on-modules

Sipeed NanoCluster is a palm-sized cluster board with seven slots for Raspberry Pi CM4/CM5, Sipeed LM3H (Allwinner H618), and/or Sipeed M4N (AXera AX650N AI SoC) system-on-modules, and other compatible SoMs might also work. The board handles inter-module communication through an 8-port RISC-V-based Gigabit switch, and supports up to 60W USB-C PD or PoE (optional) power. The NanoCluster also offers independent UART and power control for each module, and is suitable as an entry-level/educational platform for HomeLab users working with distributed computing, Kubernetes, Docker, and edge computing. Sipeed NanoCluster specifications: Supported SOMs Raspberry Pi CM4 – Broadcom BCM2711 quad-core Cortex-A72 SoC @ 1.5 GHz with VideoCore VI GPU, 1GB to 8GB RAM, up to 64GB eMMC flash (optional) Raspberry Pi CM5 – Broadcom BCM2712 quad-core Cortex-A76 SoC @ 2.4 GHz with VideoCore VII GPU, 1GB to 16GB RAM, up to 64GB eMMC flash (optional) Sipeed LM3H – Allwinner H618 quad-core Cortex-A53 […]

Linux 6.16 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just announced the release of Linux 6.16 on LKML: It’s Sunday afternoon, and the release cycle has come to an end. Last week was nice and calm, and there were no big show-stopper surprises to keep us from the regular schedule, so I’ve tagged and pushed out 6.16 as planned. It’s worth noting that the upcoming merge window for 6.17 is going to be slightly chaotic for me: I have multiple family events this August (a wedding and a big birthday), and with said family being spread not only across the US, but in Finland too, I’m spending about half the month traveling. That means that I will try very hard to get most of the merge window done the first week before my travels start, and I already ended upgiving a heads-up on that to the people who tend to send me the most pull requests.

Raspberry Pi 5 gets a microSD Express HAT

Will Whang’s RPI5-SDexpress-Hat is a small HAT+ for the Raspberry Pi 5, adding a microSD Express card slot for ultrafast storage, an eject button, and two Qwiic connectors, probably because there was still some spare space on the board… As a reminder, microSD Express cards can deliver SSD performance thanks to the use of of PCIe interface and NVMe commands. The standard was first introduced in 2019, and even earlier (2018) for full-size SD cards, but manufacturers have not exactly rushed to release compatible hardware. A major change this year is the launch of the Nintendo Switch 2 portable game console, one of the first mass market devices with a microSD Express slot, and this was partially why Will created the microSD Express HAT+ for the Raspberry Pi 5. RPI5-SDexpress-Hat board specifications: MCU – WCH CH32V003 RISC-V microcontroller for hotplugging and unmount Host interface – PCIe Gen3 x1 FFC connector […]

Three high-performance RISC-V processors to watch in H2 2025: UltraRISC UR-DP1000, Zhihe A210, and SpacemIT K3

Some high-performance RISC-V processors are in the pipeline for the rest of the year 2025, namely UltraRISC UR-DP1000, Zhihe A210, and SpacemIT K3. We currently have limited information about each of those processors, but let’s see what information we can gather from the web, mostly as a result of the recent RISC-V Summit in China. UltraRISC UR-DP1000 – Octa-core 64-bit RISC-V SoC The first SoC is the UR-DP1000 octa-core from UltraRISC (the website loads slowly, and I could not find anything about the UR-DP1000 there). It will be used in Shenzhen Milk-V Technology’s Titan mini-ITX motherboard, and Sipeed also posted the slide above on X. Preliminary UR-RP1000 specifications: CPU 8x 64-bit RISC-V UR-CP100 “RV64GCBHX” cores up to 2.0 GHz Two 4x core cluster design with 4MB L3 cache each, and a total of 16MB cache. SPECCPU2006 single-core INT @ 10.4/GHz; single-core FP @ 12/GHz Fully RVA22 compliant, and “Compliant with […]

$14 development board features GUITION ESP32-P4 + ESP32-C6 module

JC ESP32P4 M3 DEV ESP32 P4 evolution board

While searching Aliexpress for new products, I found out about the JC-ESP32P4-M3-DEV from the Maker Go AliExpress store, another ESP32-P4 development board with features very similar to the ESP32-P4-Function-EV-Board or the Wireless Tag WT99P4C5-S1 board, but built around the GUITION JC-ESP32P4-M3-C6 module, which combines ESP32-P4 and ESP32-C6 into a single package instead of having separate chips or modules on most other designs. Features include 32MB of PSRAM and 16MB of flash on the GUITION module, a microSD card slot for storage, a built-in microphone, speaker output via the ES8311 audio codec, and an audio amplifier. The board also offers a 10/100Mbps Ethernet RJ45 port, an RS-485 terminal block, a GPIO header, and expansion connectors for both the ESP32-P4 and ESP32-C6 chips. Additionally, there are three USB ports: two USB-C and one USB-A for power, data, and debugging, along with a few buttons and LEDs. JC-ESP32P4-M3-DEV evolution board specifications: Core module […]
