USB4 Version 2.0 to enable speeds of up to 80 Gbps, introduce “active” USB cables

USB4 Version 2 80Gbps

The USB Promoter Group has just pushed a press release about the “pending release” of the USB4 Version 2.0 specification that promises up to 80 Gbps of data performance over the USB Type-C cable and connector. The group also explains both the USB Type-C and USB Power Delivery (USB PD) specifications will also be updated, and everything will be published right before the USB DevDays developer events planned for November 2022 in the US and South Korea. So that’s basically an announcement about a future announcement, but we were still provided with some highlights of the upcoming USB4 v2 specification: Up to 80 Gbps operation based on a new physical layer architecture, using existing 40 Gbps USB Type-C passive cables and newly-defined 80 Gbps USB Type-C active cables. Updates to data and display protocols to better use the increase in available bandwidth. USB data architecture updates now enable USB 3.2 […]

ESP32 board with rotary encoder gets 2-key keypad shield

T-Encoder ESP32 keypad rotary encoder

LILYGO TTGO T-Encoder, a round-shaped ESP32 board with a built-in rotary encoder, has gotten a shield with a 2-key keypad based on WCH CH552 8-bit microcontroller. Launched several months ago, the TTGO T-Encoder is a USB-powered rotary encoder with ESP32 microcontroller offering WiFi and Bluetooth connectivity, and now, you can build a keypad with rotary encoder thanks to T-Encoder shield that features two mechanical switches and keycaps with RGB LED backlight.   Since we missed it at launch, let’s check out the tiny TTGO T-Encoder board specifications first: System-in-Package (SiP) – Espressif ESP32-PICO-V3-02 with MCU – ESP32 Xtensa dual-core 32-bit Xtensa LX6 microcontroller up to 240 MHz, 448 KB ROM for booting and core functions, 520 KB SRAM for data and instructions, 2.4 GHz WiFi 4 and Bluetooth 4.2 BR/EDR + LE connectivity Memory – 2MB SPI PSRAM Storage – 8MB SPI flash Dimensions – 7×7 mm Antenna – Ceramic […]

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

HydraUSB3 board

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 […]
