PortaRF single board SDR mixes HackRF One and PortaPack H4M hardware, adds AI voice control

Designed by OpenSourceSDRLab, the PortaRF is an open-source software-defined radio (SDR) that integrates HackRF One and the PortaPack H4M into a single device. It’s a standalone device that supports transmitting and receiving radio signals from 1 MHz to 6 GHz. Traditionally, a portable HackRF setup meant stacking a PortaPack on top of the main board. PortaRF replaces this with a single PCB, making it more compact, easier to use, and with improved signal quality. It also adds a larger display, more flash, and a bigger battery. PortaRF specifications: MCU – NXP LPC432 dual core ARM Cortex M4/M0 (LPC4320FBD144) microcontroller CPLD Xilinx XC2C64A CoolRunner-II AGM AG256SL100 RF ICs MAX2837 – 2.3GHz to 2.7GHz Wireless Broadband RF Transceiver RFFC5072 – Wideband Synthesizer/VCO with Integrated 30MHz to 6 GHz Mixer Frequency range – 1 MHz to 6 GHz (Transmit and Receive) Storage 2MB SPI Flash (W25Q16DV) provides more space for the Mayhem firmware MicroSD card slot […]

Discovery Drive – An ESP32-S3-based azimuth/elevation rotator for satellite dishes and SDR antennas (Crowdfunding)

KrakenRF, the team behind the KrakenSDR, has designed the Discovery Drive ESP32-S3-based, low-cost, fully weatherproof, automatic azimuth/elevation (Az/El) antenna rotator for their Discovery Dish or other directional antennas, such as Yagis and Wi-Fi grids, weighing up to 5kg. Compared to DIY projects like SatNOGS (which require 3D printing and hardware sourcing), the Discovery Drive is designed as a plug-and-play solution. You can simply mount it to a mast, attach the dish, connect to 12V power and Wi-Fi, and use its web UI to start tracking polar-orbiting weather satellites (like METEOR-M2 or FENGYUN), CubeSats, or amateur radio satellites. KrakenRF Discovery Drive specifications: Controller – Espressif Systems ESP32-S3-based control board Connectivity – 2.4 GHz 802.11 b/g/n Wi-Fi 4 (via ESP32) with external antenna Motor and Rotation Torque – Up to 125 kg·cm (12.25 Nm); supports antenna payloads up to 5 kg Azimuth Range – -360° to +360° Elevation Range – 0° to […]

Pironman 5 Pro Max Raspberry Pi 5 case gains 4.3-inch touchscreen, camera mount, speakers, microphone, and more

Pironman 5 Pro Max is the latest Raspberry Pi 5 case by SunFounder. The new enclosure adds a 4.3-inch capacitive touchscreen display, a 5MP camera module, a mount suitable for Raspberry Pi Camera Modules, stereo speakers, a USB microphone, and a 3.5mm audio jack. Besides the new features, its design is close to the Pironman 5 Max we reviewed with a Raspberry Pi 5, an NVMe SSD, and an Hailo-8 AI accelerator last June. That means it keeps black aluminum and semi-transparent black acrylic panels, offers two M.2 PCIe slots, an IR receiver, a power button, and the Tap-to-Wake feature for the OLED information display. Pironman 5 Pro Max specifications: Designed for the Raspberry Pi 5 and compatible SBCs Storage Pironman 5 Dual NVMe PiP supporting 2x M.2 2230, 2242, 2260, or 2280 NVMe SSDs at up to PCIe 2.0 x1 speeds due to switch used; RAID 0/1 support MicroSD […]

xSDR – A tiny M.2 2230 SDR module with Artix-7 FPGA and LMS7002M RFIC (Crowdfunding)

xSDR single sided M.2 software defined radio with 2× RX TX channels up to 3.8 GHz

Wavelet Lab’s xSDR is a tiny, single-sided M.2 2230 software-defined radio (SDR) module designed for integration into laptops, embedded systems, and edge computing devices. A successor to the company’s previous uSDR, the “x” in xSDR stands for “extended,” adding 2×2 MIMO support and a wider frequency range to the same tiny footprint. The module is built around the Lime Microsystems LMS7002M RFIC and an AMD Artix-7 XC7A50T FPGA as found in the LimeNET Micro 2.0 Developer Edition board. This combination allows for a tuning range of 30 MHz to 3.8 GHz and a sample rate of up to 122.88 MSPS, making this SDR suitable for cellular research (LTE/5G), spectrum analysis, satellite tracking, and high-speed data links (with two modules). Wavelet Lab’s xSDR specifications: RFIC – Lime Microsystems LMS7002M programmable RF (FPRF) transceiver IC FPGA – AMD Embedded XC7A50T (Artix-7) with 52,160 logic cells RF capabilities Channels – 2×2 MIMO (2x […]

VU GPSDR – A low-cost GPS-disciplined SDR expansion board for the Vivid Unit RK3399 touchscreen SBC

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 […]

PhaseLatch Mini – An STM32-based low-cost SDR digitizer with two 12-bit ADCs, 210 kS/s USB streaming

PhaseLatch Mini modular Software Defined Radio platform

PhaseLatch Mini is a low-cost STM32-based SDR digitizer for the previously released Phase Loom (tuner aboard), built in a Blue Pill–style form factor for HF, FM, and VHF experimentation. The board uses two 12-bit ADCs that sample I and Q at the same time, combine both readings into a 32-bit data word, and send the data over USB at about 210,000 I/Q sample pairs per second using just the standard USB CDC interface. It includes SMA inputs, a built-in ~100 kHz low-pass filter network, USB-C connectivity, ferrite-filtered power, and dedicated 8 MHz/32.768 kHz crystals for stable timing. Other features of the board include dynamic timer tuning, circular DMA, ISR-driven packet chaining, and a lock-free USB feed path to maintain high-rate streaming. PhaseLatch Mini specifications: Microcontroller – ST STM32F103C8 Arm Cortex-M3 @ 72 MHz USB Interface – USB-C 2.0 (Full-Speed) port; CDC class; RAW vendor class planned ADC subsystem Dual simultaneous […]

Improved HackRF Pro open-source SDR platform supports 100 kHz to 6 GHz operating frequency

HackRF Pro is an update to the HackRF (One) open-source SDR platform first launched by Michael Ossmann from the Great Scott Gadgets through a Kickstarter campaign in 2013 that attracted close to 2,000 backers at the time, and is still popular since then. Compared to the HackRF One, the HackRF Pro has a wider 100 kHz to 6 GHz operating frequency, features more RAM and flash memory, supports 16-bit samples for low sample rates, eliminates the DC spike, improves RF performance with a flatter frequency response, has been designed with better power management, and implements other small changes such as switching to a modem USB-C port. HackRF Pro specifications (preliminary): MCU – NXP LCP43xx dual-core Arm Cortex M4/M0 microcontroller Logic – Power-efficient FPGA (instead of Xilinx CPLD) Frequency Range – 100 kHz to 6 GHz operating frequency Tunable from 0 Hz to 7.1 GHz Transceiver – Half-duplex Sampling rates – […]
