AAEON BOXER-8224AI – An NVIDIA Jetson Nano AI Edge embedded system for drones

BOXER 8224AI board AI Edge NVIDIA Jetson Nano embedded system

AAEON BOXER-8224AI is a thin and lightweight AI edge embedded system solution based on NVIDIA Jetson Nano system-on-module and designed for drones, or other space-constrained applications such as robotics. AAEON BOXER products are usually Embedded Box PCs with an enclosure, but the BOXER-8224AI is quite different as it’s a compact and 22mm thin board with MIPI CSI interfaces designed to add computer vision capability to unmanned areal vehicles (UAV), as well as several wafers for dual GbE, USB, and other I/Os. BOXER-8224AI specifications: AI Accelerator – NVIDIA Jetson Nano CPU – Arm Cortex-A57 quad-core processor System Memory – 4GB LPDDR4 Storage Device – 16GB eMMC 5.1 flash Dimensions – 70 x 45 mm Storage – microSD slot Display Interface – 1x Mini HDMI 2.0 port Camera interface – 2x MIPI CSI connectors Networking 2x Gigabit Ethernet via wafer connector (1x NVIDIA, 1x Intel i210) Optional WiFi, Bluetooth, and/or cellular connectivity […]

EVerest is an open-source software stack for car charging stations

EVerest open source car charging station software

EVerest is a software project initiated by PIONIX GmbH, but now part of the Linux Foundation’s LFEnergy initiative, whose primary goal is to develop and maintain an open-source software stack for EV charging infrastructure. EVerest supports multiple standards and it will run on any device from AC home chargers to public DC charging stations. I noticed the EVerest project in an upcoming talk at the Embedded Open Source Summit 2023 entitled ” EVerest: Electric Vehicle Chargers With Open Hardware and Software” and whose abstract reads in part: You will learn how to build your own electric vehicle charger using open hardware designs in combination with the EVerest open-source software stack for EV charging infrastructure. Following a quick introduction to EV charging technology, with explanations of the standards, protocols, and complexities involved, the talk will go into a deep dive into how you can build your own AC charging station. Reference […]

BLIKVM open-source KVM over IP works with Raspberry Pi CM4, Raspberry Pi HAT, PCIe card, and soon Allwinner H616

BLIKVM is an open-source KVM over IP software that helps you manage servers or workstations remotely regardless of the health of the target system, and currently working with Raspberry Pi CM4 hardware, a Raspberry Pi HAT, or a PCIe board, and a new model based on MangoPi’s Allwinner H616 CPU module is coming soon. We’ve previously written about the Raspberry Pi-based PiKVM DIY project, followed by the PiKVM v3 Raspberry Pi HAT from the same project, and now I can see there’s a CM4-based PiKVM V4 that was on Kickstarter last month and raised over $800,000… You’d think this kind of system would be rather a niche market, but there’s even demand to have a similar open-source project called BLIKVM offering many of the same features since it’s based on PiKVM, except for the option to use a PCIE card fitted with a CM4 module. Highlights of the BLIKVM project: […]

PicoMQTT – An MQTT Client/Broker library for ESP8266 and ESP32

PicoMQTT is a lightweight MQTT library for Arduino/PlatformIO optimized for ESP8266 and ESP32. It not only supports the MQTT Client mode like most existing solutions but also the MQTT Broker mode which transforms an ESP8266 or ESP32 board into an MQTT gateway replacing a Raspberry Pi board or an IoT gateway typically used for this task.

The library follows MQTT 3.1.1 specification, supports the publishing and consuming of arbitrary-sized messages, can deliver thousands of messages per second, and supports easy integration with the ArduinoJson library to publish and consume JSON messages.
