UUGear’s VU GPSDR is a low-cost GPS-disciplined SDR expansion board designed specifically for the Vivid Unit, a palm-sized Rockchip RK3399-based touchscreen SBC we covered back in 2024. The VU GPSDR is built around the RTL2832U ADC and Rafael Micro R860 tuner, but what makes it different from SDRs like the PhaseLatch Mini and DeepRad SDR  is the integration of a u-blox NEO-M8N GPS module. This module provides a GPS-disciplined 24 MHz clock reference to the Si5351 local oscillator, which ensures high frequency stability and timing accuracy that is typically only found in much more expensive SDR hardware. VU GPSDR specifications: Supported Platform – UUGear Vivid Unit via Vivid Unit Extender Gen 1/2 (See details below) MCU – STM8S003F for board-level controls RF Tuner – Rafael Micro R860 ADC – Realtek RTL2832U Frequency Range – 500 kHz to 1.766 GHz Bandwidth – Up to 3.2 MHz (2.4 MHz recommended for stability) HF […]

Designed by HoneyHoneyTrading, the ESP32 Marauder 5G – Apex 5 Module is an ESP32-C5-based hacking and penetration testing tool for the Flipper Zero, with dual-band WiFi 6 (2.4GHz and 5GHz), two Sub-GHz radios (868MHz and 433MHz), an NRF24 radio, and a built-in GPS. This new Flipper Zero module can be considered an upgrade from the ESP32 Marauder – Double Barrel 5G, as it does not rely on a dual-chip configuration for 5 GHz operation, leveraging the ESP32-C5 dual-band capabilities instead. A microSD card slot handles storage, and the device can also save data directly to the Flipper Zero’s microSD card. It also features five antennas, including WiFi, Sub-GHz, nRF24, and GPS, along with dedicated LED indicators for the Sub-GHz radios and nRF24 activity. There is also a hardware button to toggle 433 MHz and 868 MHz Sub-GHz operation, a USB-C port, and a side button for power management and firmware […]

Open Stack is a standalone 4G LTE IoT connectivity board designed to run RTOS-based C applications directly on the Quectel EC200U series LTE module, meaning you don’t need an external MCU like Arduino, ESP32, or Raspberry Pi. By removing the MCU, the board reduces power consumption, bill-of-materials (BOM) cost, and physical footprint. The board supports multi-band LTE with GSM fallback, GNSS, and Bluetooth 4.2, as well as IPv4/IPv6 client and server modes. It also includes a USB Type-C port, a Nano SIM card slot, LTE/GNSS/BLE antenna connectors, an OLED information display, status LEDs, control buttons, and a 40-pin Raspberry Pi HAT-compatible GPIO header. Networking support includes TCP/UDP, SSL/TLS, HTTP/HTTPS, MQTT, LwM2M, CoAP, FTP/FTPS, and PPP, making it suitable for asset tracking, industrial monitoring, BLE-to-LTE gateways, remote infrastructure, and always-connected IoT deployments without additional controller hardware. Open Stack specifications: Cellular Module – Quectel EC200U-CN series (EC200UCNAA-N05-SGNSA) module Cellular Connectivity: LTE FDD […]

Radix UI is an open-source library of React components. Its “headless” primitives handle the complex logic and accessibility concerns—like dialogs, dropdowns, and tabs—while leaving styling completely up to the developer. The project emphasizes usability, accessibility, and composability and has become a vital part of modern web dev, in part because it forms the foundation of

Python’s popularity in data science and backend engineering has made it the default language for building AI infrastructure. However, with the rapid growth of AI applications, developers are increasingly looking for tools that combine Python’s flexibility with the rigor of production-ready systems. Pydantic began as a library for type-safe data validation in Python and has

Maybe you’ve heard: Memory is expensive now. The price of RAM has tripled, quadrupled, even sextupled depending on the type of chip, all because AI companies are gobbling it up. But maybe you’ve thought: I don’t buy memory sticks! I don’t build my own PCs! It won’t affect me, right? I’m here to tell you […]

Google has updated the iPhone version of its photo editing app Snapseed with its own camera, including a suite of manual controls and retro film emulation effects. It’s the second major update to the app in less than 12 months, after it had previously been left to languish by Google for years. The Snapseed camera […]
