ESP-SDR firmware turns ESP32 into a 2.4/5 GHz Software-Defined Radio (SDR)

We have seen ESP32s used for everything from simple IoT devices to AI, audio, and vision projects. But while looking for a new project, I found out about ESP-SDR firmware, which turns the ESP32 into a native Software-Defined Radio (SDR) without additional hardware. This open-source firmware bypasses the ESP32’s fixed-function Wi-Fi and Bluetooth modems and taps directly into the internal ADC signal chain to capture raw I/Q baseband samples. It then sends these samples to a computer over USB or UART, where they can be processed and viewed as a radio spectrum or waterfall display, turning supported ESP32 chips into low-cost...

Efinix Sapphire RV64 brings 64-bit RISC-V and Linux to FPGAs

Efinix announced this week the Sapphire RV64, a configurable 64-bit RISC-V soft SoC intended for embedded Linux, edge AI and other applications requiring more memory and processing capability than the company’s existing 32-bit Sapphire architecture. The processor can be implemented across Efinix Titanium and Topaz FPGAs, as well as Trion devices from the T20 upward. […]

UUNA TEK iAuto review – A professional handwriting and drawing machine

Hello, today I am going to review the UUNA TEK iAuto, an automatic handwriting machine designed to reproduce physical handwriting using a real pen on real paper. It also supports wireless connectivity, spreadsheet-based mail merge, custom fonts, and font variation features that can make the writing look more natural. The machine can handle paper sizes up to A3 and supports pens with a diameter of up to 18 mm. The UUNA TEK iAuto works with the manufacturer’s free iAuto software, which is available for Windows on both x64 and Arm-based systems, as well as for macOS on Apple M1, M2,...

UP Xtreme PTL Edge Air Panther Lake Mini PC gets AirJet solid-state active cooling solution

AAEON has introduced a new version of its UP Xtreme PTL Edge Panther Lake mini PC with the “Air” variant featuring Frore Systems AirJet solid-state active cooling solution. The company says the AirJet passive cooling technology makes the Panther Lake mini PC 35% thinner, 43% lighter, and capable of operating silently at under 21 dBA. This is mostly achieved by removing the thick (and heavy) heatsink found on the original design. The mini PC still benefits from up to an Intel Core Ultra X7 358H with 180 TOPS of AI performance, a 40-pin GPIO header, two RS-232/422/485 COM ports, and...

Первые отечественные электронные лифты. УЛЖМ МЯУ

Приветствую всех!

В начале года я уже как‑то рассказывал про такую станцию управления лифтом как УЛЖ-10. Тогда я рассказал исключительно про работу самих плат‑ячеек, а очень многое так и осталось за кадром. Спустя много времени мне повезло раздобыть все остальные блоки из шкафов таких лифтов, а также довольно интересный артефакт: плату, при помощи которой производилась модернизация этих станций.

Итак, сегодня детально посмотрим на начинку первой массовой отечественной электронной станции. Узнаем, как всё это соединялось и работало и при чём здесь микроконтроллеры, а главное — попробуем всё это запустить. Как водится, будет много интересного.

Four-port IO-Link module for Raspberry Pi and embedded Linux systems

Pinetek Networks has developed the IOL Core4, a compact IO-Link-compatible master module for embedded systems. It connects up to four industrial sensors or actuators over IEC 61131-9 SDCI and is intended for integration into custom control, monitoring and IIoT hardware. The module uses two Analog Devices MAX14819 dual IO-Link master transceivers. The standard PT-1204 version […]

Avaota F2 – Allwinner V861 RISC-V SBC targets AI cameras with PTZ and audio support

Avaota F2 is the first SBC based on an Allwinner V861 dual-core 64-bit RISC-V SoC with 128MB on-chip DDR3 memory, support for 4K cameras, H.265 video codec, and a 1 TOPS AI accelerator. It’s an update to the earlier Avaota F1 camera board based on an Allwinner V821 SoC. The new open-source hardware F2 SBC offers several benefits, including support for both Full HD and 4K camera sensors, motor control for the PTZ (Pan-Tilt-Zoom) feature, and improved audio support through speaker (one) and microphone (two) connectors. However, the F1 also included WiFi, which the Avaota F2 lacks. Avaota F2 specifications:...

ASRock Industrial NUC 300 series – Intel Core 3 304/Core 5 320 mini PCs and motherboards

ASRock Industrial has introduced the NUC Core 300 BOX series of mini PCs and the NUC Core 300 motherboards built around Intel Core Series 3 Wildcat Lake-U processors.

LakeShark firmware turns LilyGO T-Display P4 into a handheld ESP32-P4 SDR scanner

LakeShark is open-source firmware by Samuel Reynolds (SAMS0N1TE) that turns the ESP32-P4-based LilyGO T-Display P4 into a handheld SDR scanner. Paired with an RTL-SDR Blog V3 or V4 dongle, it supports P25 Phase I trunking, analog FM/AM, POCSAG pager decoding, and 1090 MHz ADS-B reception directly on the ESP32-P4, without a PC, Raspberry Pi, or smartphone. It also includes an onboard SX1262 that supports LoRa and MeshCore applications. SDR devices like LimeSDR Micro, xSDR, UUGear’s VU GPSDR, and many others usually rely on a PC, Raspberry Pi, or smartphone for processing, but LakeShark shows that a powerful microcontroller can also handle...
