ESP-KVM – An open-source IP KVM solution based on ESP32-P4 RISC-V MCU

Earlier this month, the P4 KVM project was brought to my attention. It provides IP KVM functionality to a Waveshare ESP32-P4-WIFI6-POE-ETH board when paired with a Toshiba TC358743 HDMI-to-CSI adapter. However, it doesn’t work with the new ESP32-P4 V3.x variants featuring a proper H.264 video encoding implementation, and the developer (Jonathan Rowny) says it’s just a proof-of-concept with many bugs and no security, so I decided to skip it. The good news is that he also encouraged others to fork the project, and Evgenij Spitsyn did just that with the release of the ESP-KVM project, which supports both MJPEG and H.264 encoding and a range of other features. ESP-KVM highlights: Video capture, resolution changes, and MJPEG or H.264 encoding Keyboard, absolute and relative pointer, media keys, copy/paste Touch mode for phones and tablets (trackpad, on-screen keyboard) Multiple viewers, one in control at a time with takeover HTTPS, login, physical password […]

Macintosh emulator works on ESP32-P4 display devkits from M5Stack and Waveshare

ESP32 chips have been used for retro gaming and computing for years, but Austin McChord (Amcchord) adds to that with a Macintosh emulator ported to a couple of ESP32-P4 display devkits. His project is a full port of the BasiliskII Macintosh 68k emulator, bringing classic Mac OS (System 7.x through Mac OS 8.1) to portable ESP32-P4 embedded devices with touchscreen, USB peripherals, and WiFi support through an ESP32-C6 on the boards. The main development platform appears to be the M5Stack Tab5 equipped with a 5-inch touchscreen display with 1280×720 resolution. However, if you need something with a larger screen, the Waveshare ESP32-P4-WIFI6-Touch-LCD-10.1 is also supported, and features a 10.1-inch display with 1280×800 resolution and a 10-point capacitive touchscreen. The actual Mac OS resolutions used are 640×360 and 640×400, respectively, then scaled twice to the native resolution of the display. Highlights of the project: CPU – Motorola 68040 emulation with FPU (68881) […]

Makerfabs MaTouch ESP32-P4 10.1-inch HMI display features 4G LTE and Ethernet connectivity, a 2MP camera

Makerfabs MaTouch ESP32-P4 TFTTouch 10.1 MIPI with 4G LTE is an ESP32-P4 + ESP32-C6-based display development platform for HMI edge AI, and connected embedded applications. The development board features a 10.1-inch IPS LCD, very similar to those of Seeed Studio’s reTerminal D1001, Waveshare ESP32-P4-WIFI6-Touch-LCD, and CrowPanel Advanced 7-inch displays. However, what makes it unique compared to other devices is that it also features a SIM7670G 4G LTE modem with a SIM card slot, an RJ45 Ethernet jack, and a 2MP camera. The HMI display also comes with microphone and speaker connectors, a microSD card slot, various USB interfaces, lithium battery support, and two 2.54 mm pitch GPIO expansion headers exposing UART, I2C, SPI, and other peripheral interfaces. All these features make it suitable for HMI, edge AI, and connected embedded applications.

SCINTIX P4 ESP32-P4 Compute Module works with (some) Raspberry Pi CM4/CM5 carrier boards (Crowdfunding)

SCINTIX P4 is an ESP32-P4 RISC-V Compute Module with an ESP32-C6 for wireless connectivity that’s compatible with Raspberry Pi CM4/CM5 carrier boards, at least partially. It should be the first MCU-based system-on-module in Raspberry Pi CM4/CM5 form factor, and RELOC says the SCINTIX P4 gives access to displays, cameras, Ethernet, USB, and all the peripherals the ESP32-P4 exposes when connected to a carrier board. It can also be programmed in standalone mode through its built-in USB Type-C port. SCINTIX P4 (RM-CMP4) specifications: SoC – Espressif Systems ESP32-P4NRW32X CPU Dual-core RISC-V @ 400 MHz with AI instruction extensions and single-precision FPU Single-core RISC-V LP (low-power) MCU @ up to 40 MHz GPU – 2D Pixel Processing Accelerator (PPA) VPU – H.264 and JPEG codecs support Memory – 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM, 32MB PSRAM Storage – 128 KB HP ROM, 16 KB LP ROM Storage […]

Wireless-Tag ESP32P4C61-TINY board combines ESP32-P4 and ESP32-C61 SoCs (Crowdfunding)

Wireless-Tag has launched a Kickstarter campaign for the ESP32P4C61-TINY, a compact open-source AIoT development board based on their WT01P461-S1 module, which combines ESP32-P4 (general-purpose) and ESP32-C61 (wireless) RISC-V SoCs. Like other ESP32-P4 boards, including the ESP32P4C5 Core Board, the M5Stack Stamp-P4, or ESP32-P4-Pi-VIEWE, this one also uses a separate SoC (ESP32-C61) for wireless connectivity. Additionally, it features built-in MIPI CSI and DSI for camera and display support, along with a microSD card slot for storage, making it suitable for AIoT and edge computing applications. ESP32P4C61-TINY Specifications Wireless Module – Wireless-Tag WT01P461-S1 (25 x 25mm) Microcontroller – ESP32-P4 MCU Dual-core RISC-V microcontroller @ 360/400 MHz with AI instructions extension and single-precision FPU Single-RISC-V LP (Low-power) MCU core @ up to 40 MHz GPU – 2D Pixel Processing Accelerator (PPA) VPU – H.264 and JPEG codecs support Memory – 768 KB HP L2MEM, 32 KB LP SRAM, 8 KB TCM, 16/32MB PSRAM Storage – 128 KB HP […]

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

MiixKeyPro (previously 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. MiixKeyPro fixes this by adding a touchscreen and allowing the user to manage over 3,000 passwords fully offline. MiixKeyPro 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 @ […]
