Waveshare RP2040-PiZero board is a Raspberry Pi Zero lookalike that features a Raspberry Pi RP2040 microcontroller instead of a Linux-capable application processor. But RP2040 board comes with the same layout as the Raspberry Pi Zero and similar ports including two USB Type-C ports, a mini HDMI/DVI connector, a microSD card slot, and a 40-pin GPIO header, but also adds support for LiPo batteries with a 2-pin connector and a charging circuit. RP2040-PiZero specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ microcontroller @ 133 MHz with 264 kB of embedded SRAM Storage – 16MB SPI flash, microSD card slot Video – Mini HDMI port that can output DVI signals USB – 1x USB Type-C port for data using PIO-USB host/device implementation Expansion – 40-pin color-coded header with 2x SPI, 2x I2C, 2x UART, 4x 12-bit ADC, 16x PWM, 8x Programmable I/O (PIO) state machines for custom peripheral support Misc – […]
Ollie v2 USB to UART/CAN/RS485/RS232 converter gets USB-C port, plastic enclosure, and more (Crowdfunding)
Ollie v2 is an improved version of the Ollie USB to isolated UART, CAN Bus, RS232, and RS485 converter that gains a USB-C port, a plastic case, the ability to set the voltage from the target board, and various other minor improvements. Like the first version, the Ollie v2 is a portable tool designed for hackers and field engineers that allows them to work with a single device instead of a bunch of USB converters, each handling a single protocol, and isolation makes sure the host, such as a laptop, is protected from high voltages. Ollie V2 specifications: Serial chip – WCH CH344 quad-serial port chip (instead of XR21V1414 in the first design) Host interface – USB Type-C port Isolated interfaces (all with ESD protection) 2x UART ports up to 6 Mbps with 1.8/3.3/5 V or target voltage levels (set by slide switch) CAN 2.0A/B up to 1 Mbps bus […]
Intel N100 mini PC offers eight USB ports, NVMe and SATA storage
We’ve already written about many mini PCs powered by the Intel Processor N100 SoC and other SKUs part of the Alder Lake N-series family, but the HUNSN BM34 is a bit different as it offers eight USB ports, with two USB 3.0 and six USB 2.0 ports that should remove the need for an external USB hub for most use cases. The fanless mini PC ships with up to 16GB DDR4 memory, supports one mSATA SSD, one NVMe SSD, and one 2.5-inch SATA drive, and offers two HDMI ports and DisplayPort video output, plus dual GbE, WiFi 5, and two audio jacks for speaker and microphone. HUNSN BM34 specifications: SoC – Intel Processor N100 quad-core Alder Lake-N processor @ up to 3.4 GHz (Turbo) with 6MB cache, 24EU Intel HD graphics @ 750 MHz; TDP: 6W System Memory – Up to 16GB DDR4 via SO-DIMM socket Storage 1x mSATA socket, […]
Thunderbolt 5 to deliver up to 120 Gbps bandwidth, support multiple 8K monitors
Intel has just announced Thunderbolt 5 and demonstrated it with a prototype laptop and dock (see the video embedded at the end of this post) with up to 120 Gbps bandwidth when using “Bandwidth Boost”. Thunderbolt 5 will deliver 80 gigabits per second (Gbps) of bi-directional bandwidth and the top 120 Gbps bandwidth is achieved through “Bandwidth Boost” to support multiple 8K monitors, which means three times the bandwidth of Thunderbolt 4 topping at 40 Gbps. Thunderbolt 5 builds upon Thunderbolt 4 with several improvements and features: Two times the total bi-directional bandwidth, and up to three times (120 Gbps) for video-intensive usage Double the PCI Express data throughput for faster storage and external graphics. Compatible with USB4 V2, DisplayPort 2.1, and PCI Express Gen 4 Double the bandwidth of Thunderbolt Networking for high-speed PC-to-PC connections. PAM-3 signaling technology to deliver increases in performance with today’s printed circuit boards, connectors, […]
SMLIGHT SLZB-06M Zigbee 3.0 PoE adapter gets Silabs EFR32MG21 microcontroller
SMLIGHT SLZB-06M is a Zigbee 3.0 to Ethernet, PoE, USB, or WiFi adapter designed to work with multi-vendor software systems such as Zigbee2MQTT and Home Assistant ZHA. This will let you integrate any supported Zigbee devices into smart home automation systems like Home Assistant, OpenHub, or HomeSeer. The SLZB-06M is a variant of the SLZB-06 Zigbee PoE adapter introduced last year with the main difference being the Zigbee chip as the new model is equipped with Silicon Labs EFR32MG21 microcontroller instead of Texas Instruments СС2652Р. An ESP32 WiFi and BLE chip is still used to work with peripherals such as the LAN8720 Ethernet chip and a CP2102N USB/UART converter chip. SMLIGHT SLZB-06M specifications: Wireless SoCs Silicon Labs EFR32MG21 Arm Cortex-M33 microcontroller @ 80 MHz with 352KB flash, 1024KB ROM for protocols and library functions, 96KB SRAM, integrated power amplifier, Bluetooth 5.2 Low Energy and 802.15.4 radios (Zigbee and Thread) Espressif […]
Linux 6.5 release – Notable changes, Arm, RISC-V and MIPS architectures
Linus Torvalds has just announced the release of Linux 6.5 on the Linux Kernel Mailing List (LKML): So nothing particularly odd or scary happened this last week, so there is no excuse to delay the 6.5 release. I still have this nagging feeling that a lot of people are on vacation and that things have been quiet partly due to that. But this release has been going smoothly, so that’s probably just me being paranoid. The biggest patches this last week were literally just to our selftests. The shortlog below is obviously not the 6.5 release log, it’s purely just the last week since rc7. Anyway, this obviously means that the merge window for 6.6 starts tomorrow. I already have ~20 pull requests pending and ready to go, but before we start the next merge frenzy, please give this final release one last round of testing, ok? Linus The earlier […]
Orbbec Femto Bolt 3D depth and RGB USB-C camera supports Microsoft ToF technology
Orbbec Femto Bolt is a 3D depth and RGB USB-C camera developed in collaboration with Microsoft and integrating the same ToF (Time-of-Flight) technology as found in the Microsoft Azure Kinect camera module and HoloLens 2 mixed reality head-mounted display. The new model follows the launch of the fully integrated Femto Mega featuring an NVIDIA Jetson Nano module introduced in January with the same ToF technology, so the new USB-C camera simply allows a wider selection of hosts. Orbbec has also launched the Femto Mega I variant with an IP65 metal enclosure. Orbbec Femto Bolt specifications: Cameras Depth camera 1 Mega Pixel ToF sensor 850nm wavelength 0.25 to 5.45m range depending on the depth mode Up to 1024×1024 @ 15 fps (WFoV) or 640×579 @ 30 fps (NFoV) FoV Wide – H: 120°; V: 120° Narrow – H: 75°; V: 65° RGB camera 4K resolution up to 3840×2160 @ 25 fps […]
RTL-SDR Blog V4 dongle launched with Rafeal R828D tuner chip
RTL-SDR has just launched the RTL-SDR Blog V4 dongle for software-defined radio (SDR) enthusiasts based on the Rafael R828D tuner chip with three switchable inputs instead of the R860 chip used in RTL-DSR Blog V3 dongle. The new model still features the Realtek RTL2832U demodulator found in all previous versions of the SDR USB dongles but adds basic input filtering, integrates an improved LDO for the power circuity leading to fewer heat emissions, and improves HF reception thanks to a built-in upconverter. The main RTL-SDR Blog V4 dongle improvements include: Improved HF Reception thanks to a built-in upconverter instead of using a direct sampling circuit. Some positive consequences are that there’s no more Nyquist folding of signals around 14.4 MHz, improved sensitivity, and adjustable gain on HF. Improved filtering thanks to the three inputs of the R828D tuner chip found in the V4 dongle. Three bands (HF, VHF, and UHF) […]
