Checking Out Dodocool DC30S USB type C Hub with USB 3.0 Ports, Power Delivery, HDMI Output, and Card Reader

I reviewed Vorke Z3 Android mini PC last month, the first mini PC I’ve received with a USB type C port capable of handling video output too. I could see support for dual HDMI displays in the firmware, but at the time I did not have a USB type C hub with HDMI output. But Dodocool sent me their DC30C USB type C hub so I’ve finally been able to give a try. Dodocool DC30S Specifications USB Input – 13 cm USB 3.1 Type-C cable USB Outputs – 3x USB 3.0 type A ports up to 5 Gbps; 1x USB 3.1 Type-C PD charging port Video Output – HDMI port Storage – SD & Micro SD card reader Dodocool DC30S Unboxing First the package which gives basic info about the USB hub. The device comes with a warranty registration card, and a multi-language user manual. One side comes with the […]

USB 3.2 To Bring 20 Gbps Transfer Rate to Existing USB type C Cables

The USB 3.0 Promoter Group has recently announced the upcoming USB 3.2 specification that defines multi-lane operation for compatible hosts and devices, hence doubling the maximum theoretical bandwidth to 20 Gbps. Only USB Type-C cables were designed to support multi-lane operation, so other type of USB cables will not support USB 3.2, and stay limited to 10 Gbps. USB 3.2 will allow for up to two lanes of 5 Gbps, or two lanes of 10 Gbps operation, so if you want to achieve 20 Gbps transfer rate, you’ll need a USB Type C cable certified for SuperSpeed USB 10 Gbps, beside hosts and devices that comply with USB 3.2. Anandtech explains that two high speed data paths are available in USB type C connector as shown above, which are also used for alternate modes, and the USB 3.1 standard makes use of one of those paths for 10 Gbps transfer, […]

USB type C to HDMI Cables Coming Soon thanks to HDMI Alt Mode for USB Type-C

Some devices already support video output over a USB type C connector, but they normally rely on DisplayPort over USB type C, so you’d either need a monitor that supports DisplayPort, or some USB Type C to HDMI converter. A DisplayLink dock is another solution, but again it converts video and audio signals. But soon you’ll be able to use a simple USB type C to HDMI cable between a capable device (camera, phone, computer, TV box…) and any HDMI TV or monitor. This is being made possible thanks to HDMI Alt Mode for USB Type-C  that supports all HDMI 1.4b features including: Resolutions up to 4K (@ 30 Hz) Surround sound Audio Return Channel (ARC) 3D (4K and HD) HDMI Ethernet Channel (HEC) Consumer Electronic Control (CEC) Deep Color, x.v.Color, and content types High Bandwidth Digital Content Protection (HDCP 1.4 and HDCP 2.2) There’s no video or audio conversion inside […]

Qualcomm Announces Audio Platforms for Smart Speakers, Headphones, and Hearables

Smart speakers are getting a lot of buzz recently with products like Amazon Echo or Google Home, and many home automation products are advertised with Amazon’s Alexa support, so that they can be controlled by voice commands. Qualcomm is now going after this market, and others audio markets via 5 new platforms for streaming audio, high resolution audio, wireless audio, USB -C audio devices – due to the “death” of the 3.5mm headphone jack -, and hearables. The five platforms include: Bluetooth and BLE Audio SoCs such as Qualcomm CSRA68100 for premium wireless speakers and headphones. The SoC comes with flash, DSP, a 2-ch audio CODEC, USB & I/Os interfaces. Qualcomm QCC3xxx entry-level Bluetooth audio SoC for mid to low-cost Bluetooth headsets and speakers. Qualcomm WHS9420 (192kHz/24-bit audio) and WHS9410 (entry-level) USB-C audio SoC for USB-C headphones Qualcomm DDFA Digital Amplifier Technology with CSRA6xxx amplifier Smart Speaker Platform shown above […]

Intel To Make Thunderbolt 3 Royalty-free, Release Specifications

Intel Thunderbolt 3 is a single port connect that supports multiple standards (Thunderbolt, USB 3.1, DisplayPort, PCIe), leverages USB-C connector, and offers up to 40 Gbps throughput. So far, it’s mostly found in higher end computers and laptops, but Intel has now announced plans to make it royalty-free, and “release the  specifications to the industry” (so maybe not completely free/public) in order to increase adoption of the standard. Thunderbolt-3 main features: Thunderbolt, USB, DisplayPort, and power on USB-C USB-C connector and cables (small, reversible) 40 Gbps Thunderbolt 3 – double the speed of Thunderbolt 2 Bi-directional, dual-protocol (PCI Express and DisplayPort) 4 lanes of PCI Express Gen 3 8 lanes of DisplayPort 1.2 (HBR2 and MST) Supports two 4K displays (4096 x 2160 30bpp @ 60 Hz) USB 3.1 (10 Gbps) – compatible with existing USB devices and cables DisplayPort 1.2 – compatible with existing DisplayPort displays, devices, and cables […]

This $8 USB Transceiver Can Add 433 MHz Device Support to your Home Automation Gateway

With the advent of WiFi and Bluetooth IoT, 433 MHz devices are becoming less popular but are still used for doorbells, motions sensors, windows/door sensors, etc… If you have such devices at home, one way to integrate those into your home automation system is to use an ESP8266 WiFi to 433 Mhz bridge between your gateway and 433 MHz capable products. However, you don’t even need the middleman if you use a USB 433 MHz transceiver connected directly to the gateway. Nathan Chantrell found such USB dongle on Banggood for about $8, and managed to make it work with his Debian Gateway using Node-RED. 433 MHz USB dongle and features: Connectivity 433 MHz transceiver Range – up to 30 to 100 meters (Line of Sight) Tx and Rx for PT2262, PT2260, PT2264, PT2240, EV1527, HS2303-PT codes Can transmit multiple signals independently Control interface – Serial over USB @ 9600 bps […]

$59 HDFury Universal PSU Doctor Supports Power Monitoring via iOS or Android

We’ve recently covered Cambrionix PowerPad 15S, a high-end 16-port USB hub that can deliver 5V/2.1A on each port, integrates power monitoring function, and an API to control and monitor each port individually. That’s a very cool device, but it’s also expensive at around $600, and even the cheaper PowerPad 15C without data pins, come at $200. If you don’t need the complete set of features offered by Cambrionix devices, but you’ll like to get a reliable multi-port USB charger with power monitoring function, HDFury Universal PSU Doctor could be an interesting option. HDFury Universal PSU Doctor specifications: MCU – Renesas RL78 16-bit MCU USB – 3x USB ports with 2x 5V ports up to 5V/2.14A, 1x USB QC 2.0 port supporting 5V/2.14A, 9V/1.6A or 12V/1.2A output ADC – Up to 11 channels, 10-bit resolution for power monitoring Sensor – n-chip temperature sensor Power Supply Built-in 100 ~ 240V AC with […]

Selecting a Micro USB Cable to Power Development Boards or Charge Phones

Yesterday one person contacted me on Facebook asking me whether there was any chance of me doing a “which usd-micro usb cable is best”, as there’s not much clear information on the Internet. His purpose was to charge his phone, but many development boards come with a micro USB port, and I’ve read many comments about powering the board. It also happened to me, and the main cause can either be the power supply which does not work as rated (usually 5V/2A), or the micro USB cable which may have a resistance a little to high leading to voltage drops. You’ll know you may have a power problem when the board refuses to boot, and usually boot loop, or randomly reboots especially under high load. The first solution is to get a power supply that provide the right voltage and amperage, and you can test that with USB Charger doctor […]
