PicoPD Pro – An open-source RP2040 development board with USB PD support up to 30V

PicoPD USB PPS/AVS development board

The PicoPD Pro is an open-source Raspberry Pi RP2040 development board that integrates USB PD support up to 30V, and features like voltage negotiation and power delivery while still retaining the Raspberry Pi Pico functionality. It features the AP33772S USB-C PD3.1 sink controller from Diodes Incorporated. The AP33772S supports the full USB-C PD 3.1 specification, including Extended Power Range (EPR) / Adjustable Voltage Supply (AVS) up to 28V and Programmable Power Supply (PPS) up to 21V. The PicoPD Pro USB PPS/AVS development board is ideal for powering devices with specific requirements, such as motor control boards, LED drivers, custom battery chargers, and other high-power applications. It also features a 5V rail output for less demanding applications. It can also be used as an AP33772S evaluation board. We have previously seen other USB-C PD solutions like the Spark Analyzer, YULC LED Controller, and USB Insight Hub which may serve a similar […]

Luckfox Pico WebBee – A Rockchip RV1103 USB & Ethernet development board for web servers, scripting, and Smart Home applications

Luckfox Pico WebBee Rockchip RV1103 development board

Luckfox has launched the Pico WebBee, a Linux-based micro development board powered by the Rockchip RV1103 Cortex-A7 SoC with 64MB of on-chip RAM. Externally, the Pico WebBee resembles a USB dongle enclosed in an ABS case with a USB Type-A port and a 100Mbps Ethernet RJ45 port. Additionally, it includes an internal microSD card slot and a boot button. The board is designed for applications such as lightweight web servers, USB scripting tools, and smart home devices. It’s not quite the first Rockchip RV1103 solution from Luckfox, as we previously covered the Luckfox Pico Mini Arm Linux camera board and the Luckfox Pico Plus camera board with an Ethernet port. The Pico WebBeee is quite different in its form factor (it’s a complete device), and it also lacks a camera interface. Luckfox Pico WebBee specifications: SoC – Rockchip RV1103 G1 CPU – Single-core Arm Cortex-A7 processor @ 1.2GHz + RISC-V […]

SignalSDR Pro is a high-performance software-defined radio (SDR) in Raspberry Pi form factor (Crowdfunding)

Raspberry Pi SDR board with AMD Zync 7020 SoC FPGA

The SignalSDR Pro is a Raspberry Pi-sized SDR that brings a credit-card-sized twist to software-defined radios (SDRs). It is a compact, streamlined device suitable for tasks ranging “from signal processing and spectrum analysis to communication systems and beyond.” The SignalSDR Pro builds on the Analog Devices AD9361 radio transceiver and the AMD Zync 7020 SoC into a credit-card format reminiscent of Raspberry Pi single-board computers. The Raspberry Pi-sized SDR also features a 40-pin GPIO header for expansion with other hardware components and added functionality. The device offers a 70MHz – 6GHz tuning range, 12-bit sample rate, 61.44MHz RF bandwidth, and two full-duplex TX/RX channels via four I-PEX antenna connectors. It is also capable of emulating other SDR hardware such as the ADALM-PLUTO and USRP B210, making it easier to integrate into pre-existing workflows. The SignalSDR Pro is a mid-range alternative to entry-level SDR options such as the AntSDR E200, KrakenSDR, […]

Sanwa Supply unveils a mouse with receiver acting as a USB/HDMI dock, and a 360-degree USB-C cable

Sanwa Supply wireless mouse USB dock HDMI

Japanese company Sanwa Supply has introduced two unusual devices to the market. First, a wireless mouse with an RF receiver that also acts as a USB dock with HDMI output, followed by a 360-degree USB-C cable to facilitate cable management. Sanwa Supply RF mouse with USB/HDMI dock Sanwa Supply 400-MAWBT209BK (black and silver) and 400-MAWBT209BK2 (black and blue) wireless mice come with a rather large USB Type-C 2.4GHz RF and Bluetooth receiver that not only allows the user to connect the mouse to a computer but also acts as a USB dock with an HDMI output port supporting up to 4Ko60 resolutions for monitors or projectors. The dock also exposes a 5 Gbps USB 3.2 Gen 3 USB Type-C port with PD support up to 100W (90W available to peripherals) which allows the users to connect peripherals such as USB SSD enclosures, memory sticks, and keyboards. Tom’s Hardware reports the […]

T-Keyboard-S3 Pro 4-Key USB mechanical keyboard adds rotary encoder, support for daisy-chaining up to six keyboards

LILYGO T-Keyboard-S3 Pro

Last year, we featured the T-Keyboard-S3, a USB mechanical keyboard with ESP32-S3, and four mechanical keys each fitted with a 0.85-inch color display. The upgraded T-Keyboard-S3-Pro adds a rotary encoder and four magnetic interfaces on each side controlked by an STM32G030 MCU to daisy-chain the host keyboard with up to 5 slave keyboards in a 3×2 grid. Previously, we featured the ANAVI Macro Pad 12, Macro Pad 10, and Macro Pad 2 programmable keyboards. Feel free to explore those as well. LILYGO T-Keyboard-S3 Pro specifications: Wireless module – ESP32-S3-WROOM-1 used in the host model only MCU –  ESP32-S3R8 dual-core LX7 microprocessor @ up to 240 MHz with Vector extension for machine learning Memory – 8MB PSRAM Storage – 16MB SPI flash Connectivity – WiFi 4 and Bluetooth 5 with LE/Mesh PCB antenna Secondary MCU – STMicro STM32G030F6P6 for I2C magnetic connectors CPU – Arm 32-bit Cortex-M0+ CPU, frequency up to […]

ORICO COM2-T3 review – A 40Gbps SSD enclosure tested with a 7000MB/s M.2 NVMe SSD

ORICO COM2-T3 40Gbps SSD enclosure review

ORICO sent me a COM2-T3 SSD enclosure capable of 40 Gbps speeds for review along with the company’s 1TB O7000 NVMe SSD rated at up to 7000MB/s read speed which converts to about 56 Gbps and should be plenty enough to test 40 Gbps SSD enclosure. Thunderbolt 4 and USB4 are not always equivalent But before going into the review itself, here’s some background information. When I test the USB-A and USB-C ports in mini PC reviews, I rely on an ORICO M234C3-U4 NVMe SSD enclosure with an Apacer SSD. That enclosure was falsely advertised as a “USB4″ enclosure but still works at 40Gbps with an Intel JH7440 Thunderbolt 3 chip that works with 40 Gbps USB Type-C ports and a JMS583  “USB 3.1 Gen 2 to PCIe NVMe Gen3” bridge for USB 3.0 ports up to 10 Gbps. I always assumed a 40Gbps USB-C peripheral would always work with […]
