The RPGA Feather dev board pairs RP2040 chip with a Lattice iCE40 FPGA for sensor fusion projects
Oak Development Technologies’ RPGA Feather board integrates the Raspberry Pi RP2040 microcontroller with the iCE5LP4K FPGA from Lattice Semiconductor into a compact development board in the Adafruit Feather form factor. The iCE5LP4K FPGA is an ultra-low-power chip in the iCE40 Ultra product family designed for mobile applications such as smartphones, tablets, and handhelds, while the Raspberry Pi RP2040 microcontroller makes it much easier to program the FPGA using CircuitPython. We have seen Oak Development Technologies’ earlier forays into FPGA Feather-compatible products such as the IcyBlue board (also based on iCE5LP4K FPGA) and the Lattice FeatherWing.

$20 Zigbee & Z-Wave mPCIe module targets Home Assistant gateways
Mixtile’s “2-in-1 Zigbee & Z-Wave mPCIe module” is a relatively inexpensive way to add Zigbee and Z-Wave connectivity to a Home Assistant server without having USB dongles sticking out of the server and taking some of its spare USB ports. The module is compatible with any computer, gateway, or SBC with a spare mini PCIe socket featuring a USB 2.0 interface such as Rockchip RK3568-powered Mixtile Edge 2 Kit gateway. You’ll also need some way of mounting the antennas after connecting them to the IPEX-1 antenna connectors on the module, the Edge 2 Kit comes with multiple antenna holes. Mixtile 2-in-1 Zigbee & Z-Wave mPCIe module specifications: Wireless MCUs Silabs EFR32MG24 Arm Cortex-M33 @ 78.0 MHz with 256 kB RAM, 1536 kB flash Radio Frequency – 2.4 GHz (802.15.4 radio) TX Power – up to +19.5 dBm RX sensitivity – -105.4 dBm at 250 kbps Protocols – Zigbee, Matter, Thread […]
SONOFF Zigbee Bridge Ultra Review – eWelink app, Matter Bridge, Turbo Mode for extended range, and Home Assistant
We have received two more Zigbee smart home products from ITEAD to review. It appears that SONOFF has strategically introduced a variety of Zigbee devices in the first half of this year. The first one we will be reviewing is the SONOFF Zigbee Bridge Ultra, which we believe will eventually replace the Zigbee Bridge (2020) and Zigbee Bridge Pro (2022) and comes with additional features, such as being a Matter Bridge. The second device we’ve received is the SONOFF Micro Zigbee USB Adapter for which we’ll post a review in the next few days, But first, let’s dive into the SONOFF Zigbee Bridge Ultra review. Overview SONOFF Zigbee Bridge Ultra (Ultra for short and also called SONOFF ZBBridge-U) is a multi-functional device. Compared to its predecessor, the Zigbee Bridge Pro, the Ultra shows big improvements in features and hardware specs. It boasts a much more powerful chip (Rockship RV1109 vs. […]

GateMate Integrated Logic Analyzer (ILA) deep dive
CNXSoft: This is a guest article by Dave Fohrn, Embedded Software Engineer at Cologne Chip AG, that goes into detail about the company’s open-source integrated logic analyzer (ILA) for GateMate FPGA chips. A field-programmable gate array (FPGA) is a highly flexible integrated circuit in which complex logic circuits can be configured. They are often used as custom computing units in digital circuits because of their ability to process data quickly and in parallel using individually configured circuits. The digital circuits designed specifically for FPGAs are usually developed in a hardware description language such as Verilog or VHDL and are known as gateware. The term “gate” refers to the configurable digital logic units in the FPGA on which the individual gate circuits are implemented. An effective design can accelerate the computing process by strategically utilizing the various resources available in the FPGA, processing data in parallel, and intelligent implementing pipelining. A […]
ThingPulse Pendrive S3 ESP32-S3 USB stick comes with 128MB of storage and a capacitive spring button
The Pendrive S3 is an ESP32-S3 development board in a USB stick enclosure with 128MB of flash memory and an unusual capacitive touch button. The Espressif ESP32-S3-MINI-1 module on the board integrates an Xtensa dual-core 32-bit LX7 microprocessor with support for 2.4GHz Wi-Fi and Bluetooth 5 (low-energy). The device features a capacitive touch button that can be used to trigger actions by touching the enclosure. The capacitive button isn’t visible on the exterior of the device, which helps the device maintain a low profile. You may be interested in Dani Eichhorn’s article on how he came up with the idea of using a spring for the capacitive touch button. The Pendrive S3 stick can be used as a BadUSB device for hacking and penetration testing purposes. With the aid of SuperWiFiDuck, it can perform keystroke injection attacks. All scripts can be managed and controlled wirelessly via a web interface, and […]
LattePanda Mu review – Part 1: an Intel N100 Compute Module tested with Windows 11, carrier boards with PCIe slots
Last April, DFRobot launched the LattePanda Mu x86 Compute Module powered by an Intel N100 Alder-Lake processor with 8GB RAM and a 64GB eMMC flash along with Lite and Full function carrier boards for evaluation. End customers will typically design their own carrier board without having to take of high-speed signals for the LPDDR5 memory and other complexities during the PCB layout. DFRobot has sent us the LattePanda Mu module for review along with the Lite and Full Function carrier boards, a heatsink for passive cooling, and an active cooler so we can compare both cooling solutions. Let’s have a look at the LattePanda Mu module and accessories before testing the kit with the Windows 11 operating system, including the PCIe x4 slot. LattePanda Mu kit unboxing The parcel included three retail boxes. The smallest box housed the LattePanda Mu Compute Module, a heatsink, and an active cooler. The second […]
