Standard GPS receivers only achieve around two-meter accuracy, which is insufficient for precise robotic navigation. RTK (Real-Time Kinematic) GPS solves this by using a base station at a known location to transmit phase-angle correction data to a mobile receiver, enabling centimeter-level accuracy. GreatScott! demonstrates this on a tracked robot platform, placing the base station on a fence post and the RTK receiver on the robot. While the RTK system itself proved accurate enough, the robot's steering hardware and algorithms became the limiting factor for hitting centimeter-sized targets. The setup demonstrates practical applications like autonomous lawn mowing and amateur land surveying.

Bảng phát triển RP2350B Bells&Whistles tích hợp sẵn bộ gỡ lỗi RP2040 (Picoprobe), cổng HDMI (qua PicoDVI), khe cắm thẻ microSD, PSRAM 8MB tùy chọn, flash SPI 4MB, 46 chân GPIO và hai cổng USB-C. Bo mạch hỗ trợ nguồn mở (KiCad, sơ đồ trên GitHub) với giá 29,95 USD trên Tindie.
Lập trình viên muốn phát triển ứng dụng trên RP2040 nhưng gặp khó khăn với việc debug và mở rộng hệ thống cần tìm hiểu cách tích hợp RP2350B để tiết kiệm chi phí và tăng hiệu năng với các tính năng như debug built-in, HDMI, và lưu trữ MicroSD.
OpenC6 BIOS is an open-source project that brings PC BIOS-like architecture to the ESP32-C6 microcontroller. Instead of combining hardware setup and application code into a single firmware image, it separates the base system from application payloads (2–10 KB). Key features include dynamic CPU frequency scaling, a System Call Interface (ABI) for Wi-Fi/crypto/math access without full ESP-IDF, PXE-like network boot over Wi-Fi, A/B OTA updates with rollback, a web-based BIOS setup interface, LP-Core health monitoring using the ESP32-C6's low-power RISC-V core, and Aura Sync RGB support. The project targets ESP32-C6 boards with at least 8MB flash and is available on GitHub under the MIT license.
The Gea stack enables developers to write CSS and TypeScript for ESP32 microcontrollers, compiling it into native C++ firmware. A demo shows a smooth 3D cube animation running at up to 60 FPS on a 410×502 AMOLED screen with full color and transparency support. It's not a full browser engine — limitations include no hover states, rasterized fonts, and a 512-node UI tree cap — but it lets web developers leverage familiar skills for embedded UI development without major performance loss.

Iridium Communications has launched the 9604 module and development kit, a hybrid IoT platform combining satellite (SBD), LTE-M cellular, and GNSS into a single compact module (16×26×2.4 mm). Built on the u-blox SARA-R5 platform, it can reduce board space by over 60% versus discrete implementations. The module supports GPS, GLONASS, Galileo, and BeiDou, offers independent subsystem management for custom failover strategies, and provides a unified AT command interface with an SDK. It targets industrial monitoring, transportation, maritime, and remote asset tracking applications where terrestrial networks may be unavailable.
Tombot has closed a $7 million Series A3 round to scale manufacturing of Jennie, its autonomous robotic Labrador puppy designed as a companion for people with dementia, cognitive impairment, anxiety, loneliness, autism, and PTSD. Investors include healthcare and aging-services backers such as Caduceus Capital Partners and the Lutheran Foundation for Long Term Living. The company reports over 23,000 pre-orders and waitlist sign-ups ahead of a planned Fall 2026 commercial launch — its first shipments to paying customers. Jennie mimics the behavior of an 8-to-10-week-old puppy and is pitched as delivering companionship benefits without the care burden of a live animal.
General Intuition has raised $320 million at a $2.3 billion valuation to scale AI agents trained on hundreds of millions of hours of video game footage. The key differentiator is action-labeled gameplay data — records of button presses and timing — rather than video alone, which the company argues enables richer causal understanding. The same model powering a Fortnite-playing agent also drives a quadrupedal robot that required only 8 minutes of real-world fine-tuning. The round was led by Khosla Ventures with participation from Jeff Bezos, Eric Schmidt, and Google DeepMind researchers. General Intuition plans to sell its agentic model as a foundation for gaming, simulation, and robotics use cases via an API, while also launching Nerve, a jobs marketplace letting gamers earn income through data labeling and robot teleoperation.
Orange Pi 6 is a new compact SBC (90x90mm) powered by the CIX P1 (CD8180) 12-core Arm Cortex-A720/A520 SoC with up to 32GB LPDDR5 RAM. Compared to the larger Orange Pi 6 Plus, it features 2.5GbE instead of 5GbE networking, drops LiPo battery support, and comes in a smaller form factor. Key specs include dual M.2 PCIe Gen4 x4 slots, multiple display outputs, a 28.85 TOPS NPU, and support for Debian, Ubuntu, Android, Windows 11, and OpenHarmony. Pricing starts at $239 for the 8GB model, reflecting the high cost of LPDDR5 RAM, making it significantly pricier than typical Orange Pi boards.
Geoffrey Wells designed ChillPoint, a handheld iButton reader built around an ESP32-C6 microcontroller, aimed at modernizing cold chain logistics data retrieval. The device uses a 1-Wire probe to read iButton temperature data loggers on contact, stores data on internal flash, and hosts a web UI over its own WiFi access point for easy access from any smartphone, tablet, or laptop. Both hardware and software will be open source, with a CrowdSupply campaign planned for release.
