XRF16 Gen3 SOM features Xilinx Zynq UltraScale+ ZU49DR RFSoC with up to 6GHz bandwidth

We’ve written about Xilinx Zynq UltraScale+ MPSoCs that combine Arm Cortex-A53/R5 cores and Mali-400 GPU with Ultrascale FPGA fabric several times over the course of a few years. But AMD-Xilinx also offers the Zynq UltraScale+ RFSoC single-chip adaptable radio platforms that support up to 7.125GHz analog bandwidth. The topic came to my attention because of an upcoming ZU49DR SoM from iWave Systems that seems to be under development but also noticed Avnet had launched a solution last year with the XRF16 Gen3 SoM featuring the same third-generation Zynq Ultrascale+ ZU49DR RFSoC with 16 RF-ADC, 16 RF-DAC channels, and 6GHz RF bandwidth. Avnet XRF16 specifications: Main chip – Xilinx Zynq UltraScale+ Gen3 ZU49DR RFSoC with Quad-core Arm Cortex-A53 processing subsystem Dual-core Arm Cortex-R5F MPCore up to 533MHz 16x ADCs, 14-bit up to 2.5 GSPS 16x DACs, 14-bit up to 9.85 GSPS (10 GSPS Available) 1 GbE, PCIe Gen1/2, SATA, USB2/3 UltraScale+ […]

Libre Computer ROC-RK3328-CC now supports Ubuntu 22.04 with Linux 5.18.2

Libre Computer’s latest Ubuntu 22.04 desktop and server images for ROC-RK3328-CC board are based on Linux mainline, namely Linux 5.18.2, and other boards from the company, based on Allwinner H2+/H5 processor or Amlogic S905X, have gotten the same treatment. Some companies will churn out boards regularly but provide limited software support. Libre Computer seems to have taken a different approach, as they released most of their board in 2017 and 2018, starting with AML-S905X-CC “Le Potato” board based on the Amlogic S905X processor, followed by ALL-H3-CC “Tritium” SBC with Allwinner H2+, H3, or H5 processor, and finally ROC-RK3328-CC “Renegade” board, but still release updated OS images in 2022. I reviewed ROC-RK3328-CC SBC with Debian 9 and Ubuntu 18.04 using Linux 4.4 in July 2018, and four years later, you might have thought such boards could have become abandonware, but Libre Computer just released Ubuntu 22.04 Desktop and Server image with […]

CANDuino v3 – A Microchip ATmega168PA board with CAN bus, Arduino Nano form factor

CANduino v3 is the third revision of MassiveButDynamic’s CAN bus board with Arduino Nano form factor based on Microchip ATmega168PA 8-bit AVR microcontroller, Microchip MCP2515 CAN controller with an SPI interface, and Microchip MCP2551 CAN transceiver suitable for 12V and 24V systems. The CANDuino v3 board is now slightly narrower in order to give access to two rows on each side when installed on a breadboard, comes with a USB Type-C port to reduce the number of cables needed, and the CAN bus function can be deactivated via a jumper in order to use the CANduino as a normal Arduino Nano. CANDuino v3 specifications: MCU – Microchip ATmega168PA 8-bit AVR microcontroller @ up to 16 MHz with 16KB flash, 512 bytes EEPROM, 1 KB SRAM CAN Bus CAN L/H header and CAN bus termination Microchip MCP2515 CAN controller connected to the AVR microcontroller over SPI. Supports CAN V2.0B at 1 […]

YD-CH32V307VCT6 RISC-V MCU board comes with Ethernet and plenty of I/Os

At the beginning of the year, we wrote about WCH CH32V307 RISC-V microcontroller and a development board with 8 UART ports controlled over Ethernet. I’ve now been informed of a similar, but much more compact by VCC-GND Studio named “YD-CH32V307VCT6”. Besides the 144 MHz RISC-V microcontroller, the board features a 10Mbps Ethernet port, two USB Type-C ports, SPI flash, EEPROM, a microSD card socket, and four rows of 24 pins each for a total of 96 pins exposing all pins out of the LQFP100 package. YD-CH32V307VCT6 board specifications: MCU – WCH CH32V307VCT6 32-bit RISC-V microcontroller @ 144 MHz with 256K Flash, 64K SRAM Storage – 32Mbit SPI NOR flash (W25Q32), 64kbit EEPROM (24C64), MicroSD card slot Networking – 10 Mbps Ethernet USB – 1x USB 2.0 Type-C port (High Speed: 480 Mbps), 1x USB 2.0 Type-C port (Full Speed: 12 Mbps) Expansion – 2x 48-pin headers with 2 x 12-bit […]

Raspberry Pi Pico clone: WeAct RP2040

WeAct RP2040 board adds 16MB flash, USB-C port to Raspberry Pi Pico form factor

If the Raspberry Pi Pico’s 2MB of QSPI flash is not quite sufficient for your needs, and you’d not quite a fan of micro USB ports, the WeAct RP2040 “clone” comes with up to 16MB flash and a USB Type-C port for power and programming. Another improvement is the addition of a reset button, which can be convenient for flashing UF2 firmware, and the pinout remains mostly the same. The price is not quite as low as the original Raspberry Pi Pico, but the board sells for an affordable $5.99 with 2MB flash, while the 16MB flash variant goes for $8.99 with shipping included in both cases. WeAct RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller @ 133 MHz (overclockable to 250+ MHz) with 264KB SRAM Storage – 2MB to 16MB QSPI flash USB – 1x USB 1.1 Type-C port used for power and programming Expansion 2x 20-pin […]

UP 4000 SBC is a Raspberry Pi lookalike with an Intel Apollo Lake processor

AAEON has unveiled the UP 4000 single board computer with a form factor and ports arrangement similar to Raspberry Pi 2/3, but powered by a choice of x86 processors, namely the Intel Atom E3900 series, Celeron N3350, or Pentium N4200 all parts of the Apollo Lake family. The first UP Board was introduced in 2015 as a device offering an x86 alternative to the Raspberry Pi 2 with an Intel Atom x5-Z8300/Z8350 “Cherry Trail” processor, but later “UP bridge the gap” boards from the company used larger “Squared” (85.6 x 90 mm) or “Xtreme” (122 x 120 mm) form factors. The UP 4000 SBC brings us back to the original business card form factor but with a boost in performance and various specifications improvements. UP 4000 vs UP Board specifications   AAEON says the new board is able to deliver 30% faster CPU performance and twice the 3D graphics performance […]
