HydraUSB3 RISC-V MCU board combines USB 3.0 with HSPI and SerDes high-speed interfaces

Benjamin VERNOUX has launched the HydraUSB3 V1 board based on WCH CH569 RISC-V MCU as a developer platform to experiment with high-speed protocols like HSPI and SerDes through a USB 3.0 interface. It’s the third board from Benjamin we feature here, after the STM32-based HydraBUS and the HydraNFC v2 shield delivering up to 1600 mW for NFC charging and connectivity. The HydraUSB3 v1 is quite different since it does not involve NFC at all, and instead leverages the CH569’s high-speed interfaces including USB 3.0 (5 Gbps), HSPI (3.8Gbps), and SerDes (>1.2Gbps). HydraUSB3 V1 specifications: MCU – WCH CH569 32-bit RISC-V (RISC-V3A) RV32IMAC MCU @ 120MHz with 16KB 32-bit SRAM, 96KB configurable 128-bit SRAM, 448KB code flash, 32KB data flash USB – 1x USB 3.0 host/device port that supports the USB 3.0 SS built-in PHY (5Gbps) and USB 2.0 built-in PHY FS/LS/HS (480Mbps) High-speed I/Os High-Speed Parallel Interface (HSPI) up to […]

Golioth ESP-IDF SDK connects ESP32 boards to the Golioth Cloud

Golioth have released an open-source “ESP-IDF SDK” to let ESP32 hardware connect to their Golioth Cloud, extending existing support from the existing Zephyr SDK. We previously covered the Golioth IoT development platform with a Zephyr SDK supporting nRF9160 and ESP32-C3 (officially), as well as over 100 other platforms, that aims to make it easier for hardware developers to connect things to the internet without needing to know how to use AWS IoT, Azure IoT, or the other cloud services. While in theory, it would be possible to keep using the Zephyr SDK on ESP32 hardware, the ESP-IDF framework is the main tool of Espressif Systems, and they will release new code to that ecosystem first. So even though Espressif Systems have another team that is bringing many of the same features to Zephyr, the changes will be implemented in the ESP-ID framework first. The Golioth ESP-IDF SDK will be able […]

reComputer J101/J202 carrier boards are designed for Jetson Nano/NX/TX2 NX SoM

Seeed Studio’s reComputer J101 & J202 are carrier boards with a similar form factor as the ones found in NVIDIA Jetson Nano and Jetson Xavier NX developer kits, but with a slightly different feature set. The reComputer J101 notably features different USB Type-A/Type-C ports, a microSD card, takes power from a USB Type-C port, and drops the DisplayPort connector, while the reComputer J201 board replaces the micro USB device port with a USB Type-C port, adds a CAN Bus interface, and switches to 12V power input instead of 19V. The table below summarizes the features and differences between the Jetson Nano devkit (B1), reComputer J101, Jetson Xavier NX devkit, and reComputer J202. Note the official Jetson board should also support production SoM with eMMC flash, but they do ship with a non-production SoM with a built-in MicroSD card socket instead. The carrier boards are so similar that if NVIDIA would […]

LILYGO 7-5 inch E-paper Display with T5 ESP32 board

$52 7.5-inch E-paper display connects to ESP32 boards

So far LILYGO’s ESP32 boards with an E-Paper display such as the TTGO T5  or Mini E-Paper Core featured smaller displays from 1.02-inch to 2.9-inch. But the company is now offering a larger 7.5-inch display that works with most of its T5 boards excluding the one used with a 4.7-inch display. The black and white e-paper display offers a resolution of 800 x 480 pixels, is Arduino programmable and backward compatible with earlier T5 E-paper solution, and should be one of the most cost-effective to way to make a wireless E-paper display. LilyGO 7.5-inch E-paper display specifications: Panel SKU – DKE DEPG0750_U790F3 (See PDF datasheet. note non-secure link so your browser may complain) Size – 7.5-inch diagonal Resolution – 800 x 480 pixels (124 DPI) Active area – 163.2 x 97.92mm Pixel pitch – 0.204 x 0.204 mm Host interface – SPI Dimensions – 170.2 x 111.2 x 1.2 mm […]

Pinecil V2 soldering iron gets BL706 Bluetooth LE RISC-V MCU, USB PD EPR support

PINE64 is about to launch the second generation Pinecil RISC-V soldering iron with the Pinecil V2 featuring a new Bouffalo Lab BL706 RISC-V microcontroller with Bluetooth LE connectivity, optimizations for higher power levels, as well as tentative support for the new USB PD EPR standard (Extended Power Range) working at up to 28V. I don’t solder every day, but when I do, I use my Pinecil soldering iron, as it’s heating super fast and does the job, and in my case, works quite better than the TS100 soldering iron. So it should come as no surprise that the Pincel is the most popular consumer hardware from the PINE64 community (after SOPine modules), and the new Pinecil V2 is a welcome upgrading building on the same design but with Bluetooth LE connectivity and a lower tip resistance. Pinecil V2 preliminary specifications: MCU – Bouffalo Lab BL706 32-bit RISC-V microcontroller @ 144 […]

5V wireless LED lights up thanks to magnetic resonance coupling technology

Wireless power, no matter how inefficient it may be, sounds good and even looks good with the “5V remote wireless power supply LED pack” we feature in this post. It also feels magical with the LEDs lighting up thanks to magnetic resonance coupling technology. The solution comes with a coil as a transmitter and each LED bead also includes a small coil as a receiver. When the two are coupled, energy can be transferred from the transmitter to the receiver through the air, paper, or plastic casing, and the LEDs will light up. The magnetic field intensity in this technology is said to be similar to that of the Earth’s magnetic field, and it will not be harmful to human health and other devices. Specifications: Transmitter Module Input Voltage – 5 V Power – 0.5W (10 LEDs) Transmitting Coil Outer Diameter – 70mm, inner diameter 65mm, thickness 0.5mm Transmitter Board […]
