M5Stack Core2 gets open-source firmware to reproduce OpenAI’s Codex Micro features

IAMLIUBO has written firmware for the M5Stack Core2 IoT controller to reproduce the features of the $230 Codex Micro macro pad for OpenAI’s AI coding agent platform, enabling developers to more easily monitor and control agents. The original is neat with a CNC-milled enclosure, a rotary encoder, and a joystick, but it’s rather pricey (and now out of stock), only ships to the US, and the company has now launched pre-orders for a 25-key “Custom Alternative” going for $125. However, you can easily reproduce the same functionality with other macro pads with rotary encoders, such as the SayoDevice O3C, DuckyPad Pro, Waveshare MK10, T-Keyboard-S3 Pro, and others at a fraction of the price by simply remapping the keys. IAMLIUBO went another route with the M5Stack Core2 IoT controller since it doesn’t come with any keys. Instead, he leveraged the 2-inch touchscreen LCD of the ESP32 device with six agent keys, […]

Espressif releases SDK for Aliro smart door locks based on ESP32-C or ESP32-H SoCs

Espressif Systems has just released the SDK for Aliro, designed for smart Matter door locks and other access control solutions built around ESP32-C (WiFi) or ESP32-H (Thread) microcontroller and third-party NFC chips. We recently wrote about the Aliro vendor-agnostic digital access control standard working over NFC, Bluetooth LE, or BLE+UWB. It’s basically the equivalent of Matter, but for smart locks, instead of the broader Smart Home ecosystem. The ultimate goal is to reduce fragmentation and allow users to use compliant wallets from Google, Apple, Samsung, and others to work with Aliro-compatible devices. Espressif’s SDK for Aliro (ESP-Aliro) currently supports the following features of Aliro-over-NFC: Standard Expedited Phase Fast Expedited Phase Reader Certificate Sending via AUTH1/LoadCert Command Keyslot to Look up Access Credential Public Key Mailbox of Exchange command Step-up Phase Espressif’s solution currently only works with Aliro NFC for tap-to-unlock applications, although Bluetooth LE and Bluetooth LE + UWB support […]

pico-usb-wifi firmware converts the Raspberry Pi Pico W into a driverless USB WiFi adapter

pico-usb-wifi is an open-source firmware project that converts the Raspberry Pi Pico W into a driverless USB WiFi adapter that works with Windows, Linux, macOS, and other operating systems with USB CDC-NCM support. The Infineon CYW43439 chip found in the SBC can’t be used directly as a USB to WiFi bridge, and instead, the firmware implements a transparent Layer-2 bridge between the Pico W’s wireless module and USB interfaces. It basically works as an Ethernet to WiFi gateway/bridge, which exposes an Ethernet connection through USB (aka USB gadget mode) used to route Wi-Fi packets from the network. pico-usb-wifi highlights: Transparent Layer-2 Bridging between the Pico W’s wireless and USB interfaces Exposed as a USB CDC-NCM device IPv4 and IPv6 with no NAT, no private subnet, and no port-forwarding to configure Out-of-band management and debug consoles over CDC-ACM serial WPA2-PSK and WPA3-SAE authentication (and open networks) Throughput – Average 4.75 Mbits/sec; […]

OpenInfrared Point is an ESP32-S3 powered universal remote hub with Infrared, BLE, NFC, audio streaming (Crowdfunding)

OpenInfrared Point is a universal remote hub built around ESP32-S3 that lets users control compatible devices from a smartphone by scanning a QR code or tapping an NFC tag, eliminating the need for dedicated remote controls. Powered via USB-C, the Point hub can learn IR codes from existing remote controls and supports infrared, IP (HTTP), and Bluetooth Low Energy (BLE) device control, with RF support planned as a future add-on. Hardware features include an IR output for external emitters, an audio input for private TV audio streaming, built-in NFC, QR-code access, and support for controlling TVs, projectors, AV receivers, air conditioners, streaming devices, and other compatible equipment.

NVIDIA launches smaller, mainstream Jetson T2000 and T3000 modules for Edge AI and robotics applications

NVIDIA has just launched the Jetson T2000 and T3000 “mainstream” modules as smaller and lower cost options to the Jetson T4000/T5000 modules introduced last year for Edge AI and robotics applications. The Jetson Thor T3000 and the industrial version IGX Thor T3000, which adds functional safety, both deliver up to 865 FP4 TFLOPS of AI compute. They feature a 1536-core NVIDIA Blackwell GPU, an eight-core Neoverse Arm CPU, 32GB of LPDDR5X memory with 273GB/s bandwidth, and 25 GbE connectivity. The Jetson Thor T2000 delivers up to 400 TFLOPS of AI performance, features a 1024-core Blackwell GPU, 16GB LPDDR5 with 137GB/s bandwidth, and 10 GbE networking. Both are about half the size of the Jetson T4000/T5000 modules. Here’s a preliminary comparison between the Jetson Thor T2000, T3000, T4000, and T5000 modules. It’s preliminary because, as I write this article, NVIDIA has yet to provide the full specifications for the new T2000 and […]
