ESP-HDMI-Bridge is an ESP32-P4-based HDMI streaming adapter based on Lontium Semiconductors’s LT8912B MIPI-DSI to HDMI bridge chip outputting MIPI-DSI video signal of ESP32-P4 to HDMI devices. It allows the user to connect a computer to an HDMI display or projector through USB, Ethernet, or WiFi, or use it directly as a digital signage player or live dashboard connected to an HDMI display. The current solution is based on the ESP32-P4-Function-EV-Board connected via its MIPI DSI connector to a 50x40mm board with the LT8912B bridge, a MIPI DSI input connector, LVDS and HDMI video outputs, and a 12-pin header with I2C, I2S audio, etc., with everything housed in a plastic enclosure. The best is to watch the video below, which shows various demos: USB to HDMI up to 720p30 or 1080p15 Ethernet to HDMI WiFi to HDMI up to 1080p40 using the ESP32-C6 2.4 GHz WiFi 6 module on the ESP-P4 [...]

CM5-DUAL-ETH-MINI-BOX is a dual gigabit Ethernet router box for the Raspberry Pi CM5
CNXSoft - Embedded Software Development par Jean-Luc Aufranc (CNXSoft) le 19/04/2025 à 06:37:00 - Favoriser || Lu/Non lu
Waveshare CM5-DUAL-ETH-MINI-BOX is a dual gigabit Ethernet router box designed for the Raspberry Pi CM5. It offers a familiar design with a metal enclosure that looks suspiciously similar to FriendlyELEC’s family of NanoPi routers powered by Rockchip processors, such as the NanoPi R2S Plus or NanoPi R3S. The router also features a microSD card slot to boot the OS on the Raspberry Pi CM5 Lite, a USB 3.0 Type-A port, a USB Type-C port for power and eMMC flash programming, power and boot buttons, and a 40-pin GPIO header accessible without opening the case (after lifting a cover). CM5-DUAL-ETH-MINI-BOX specifications: Supported SoMs – Raspberry Pi CM5 and CM5 Lite, and potentially compatible alternatives like the Raspberry Pi CM4, Orange Pi CM5, Radxa CM5, etc… Networking 2x Gigabit Ethernet RJ45 ports: one GbE exposed directly through the CM5 board-to-board connector, and the other via a RealTek RTL8111H PCIe controller WiFi 5 [...]

Openviro Axe PoE is an RP2040-based environmental sensor for server rooms and cabinets (Crowdfunding)
CNXSoft - Embedded Software Development par Jean-Luc Aufranc (CNXSoft) le 18/04/2025 à 12:47:00 - Favoriser || Lu/Non lu
Openviro Axe PoE is a rack-mountable, open-source environmental sensor designed to measure the temperature and humidity (and air pressure) in server rooms or cabinets with electrical equipment. The device is based on a Raspberry Pi RP2040 board with Ethernet connectivity housed in a plastic enclosure and equipped with two RJ12 connectors for Bosch BME280 sensors with an accuracy of +/- 0.5°C. It provides better results than sensors placed in a machine that may be impacted by the internal components’ heat dissipation. For instance, the two sensor inputs can be used to measure the temperature and humidity of the intake and exhaust in a server rack. Openviro Axe PoE specifications: Microcontroller – Raspberry Pi RP2040 dual Arm Cortex-M0+ @133 MHz with 264 KB SRAM Storage – 16 MB flash memory Network – 10/100Mbps Ethernet RJ45 port via LAN8710Ai Expansion – 2x RJ12 connector for THP Probes Misc – 3x Buttons Power [...]

Solar-powered WisMesh Repeaters extend the range of Meshtastic networks
CNXSoft - Embedded Software Development par Jean-Luc Aufranc (CNXSoft) le 18/04/2025 à 09:48:00 - Favoriser || Lu/Non lu
RAKWireless has launched two solar-powered Meshtastic range expanders/repeaters: the WisMesh Repeater with a larger battery and external solar panel, and the WisMesh Repeater Mini with a more compact design with an integrated solar panel Meshtastic open-source firmware allows LoRa nodes to be used for off-grid messaging, GPS coordinates sharing, and more. The mesh network relies on nodes to communicate with each other and relay messages to other nodes if needed. However, this does not work reliably when nodes are too far apart or one node goes offline for whatever reason. That’s when Meshtastic repeaters are needed. WisMesh Repeater / Repeater Mini specifications: WisBlock RAK4631 Core Module Wireless SoC – Nordic Semi nRF52840 Cortex-M4F MCU @ 64 MHz with 1MB flash, 256 KB RAM, BLE 5.0, pre-flashed with Meshtastic firmware LoRa transceiver – Semtech SX126x series with support for Meshtastic 8xx and 9xx MHz networks 800 MHz – RU864/ IN865/ EU868 [...]

Podcast - De l'Internet préhistorique à l'IA

Il y a quelques semaines, j’ai eu l’occasion de participer au podcast ‘Derrière La Bulle’ de Léo Pereira et c’était vraiment sympa !
On a fait un voyage dans le temps, depuis l’époque où uploader une image de 50 Ko prenait une pause café jusqu’aux IA génératives du moment et comme j’ai vécu toute cette évolution des débuts chaotiques du HTML, à l’émergence des blogs, en passant par la montée du web social, et maintenant l’ère de l’IA, j’avais plein de trucs à raconter.

VMware ESXi est à nouveau gratuit !
Korben par Korben le 18/04/2025 à 09:14:00 - Favoriser || Lu/Non lu
Vous vous souvenez quand votre ex vous a largué pour “prendre du temps pour réchéfliiiir” (oui il/elle l’a dit comme ça…) et qu’ensuite, il ou elle est revenu(e) en rampant quelques mois plus tard ?
Eh bien, VMware vient de faire pareil avec sa version gratuite d’ESXi. Après l’avoir brutalement buté début 2024, Broadcom vient discrètement de la ressusciter, comme si de rien n’était. En tout cas, c’est ce qu’on a découvert dans les notes de version de ESXi 8.0 Update 3e : “Broadcom makes available the VMware vSphere Hypervisor version 8, an entry-level hypervisor. You can download it free of charge from the Broadcom Support portal.”
