WCH RISC-V microcontrollers can now be programmed with the Arduino IDE

WCH has launched some interesting RISC-V microcontrollers in the last year or so, including the “10 cents” CH32V003 RISC-V microcontroller with 2KB SRAM and 16KB flash or the CH32V307with more resources (up to 64KB SRAM and 256KB flash) and additional peripherals. So far they were programmable in C language using MounRiver IDE or an open-source toolchain, but WCH has now announced Arduino support for many of those RISC-V microcontrollers which should enable more people to get involved. The core library for CH32duino works with OpenOCD through WCH-LINKE hardware to download the firmware and debug WCH chips and a riscv-none-embed-gcc toolchain that supports custom RISC-V instructions (half-word and byte compression instruction extensions and hardware stack push/pop functions) found in WCH RISC-V microcontroller. The following evaluation kits are currently supported with ADC, DAC, USART, GPIO, EXTI, SysTick, I2C, and SPI peripherals: CH32V003F4P EVT board CH32V203G8U EVT board CH32X035G8U EVT board CH32V103R8T6_BLACK EVT […]

Radxa X2L Intel Celeron J4125 SBC goes for as low as $39

Radxa X2L is an inexpensive Intel Celeron J4125 Gemini Lake Refresh single board computer (SBC) that ships with 2GB to 8GB RAM, an M.2 socket for SSD storage, another M.2 socket for a wireless module, and offers a range of ports such as dual HDMI, gigabit Ethernet, four USB port, and a 40-pin GPIO header. The price starts at $39, a price point that reminds me of the Atomic Pi SBC introduced a few years ago with an Atom X5 Cherry Trail processor, but the Radxa X2L is easier to use, offers better performance and modern features, as well as a low-profile form factor that’s about the size of a smartphone, just a bit thicker. Radxa X2L specifications: SoC – Intel Celeron J4125 quad-core Gemini Lake Refresh processor @ 2.0 / 2.7 GHz (Turbo) with Intel UHD Graphics 600 @ 250/750 MHz; 10W TDP MCU – Raspberry Pi RP2040 microcontroller […]

Maxtang MTN-FP750 review – Part 2: Windows 11 Pro on an AMD Ryzen 7 7735HS mini PC

In the first part of the Maxtang MTN-FP750 mini PC review, we looked at the hardware with an unboxing, a teardown, and a first boot to the pre-installed Windows 11 Pro. We’ve now spent more time testing the Maxtang MTN-FP750, also called NUC-7735HS-A16, and we will report our experience with the AMD Ryzen 7 7735H mini PC in Windows 11 Pro with a software overview, features testing, benchmarks, storage and network performance testing, cooling performance, fan noise, power consumption, and more. Software overview and feature testing The Maxtang MTN-FP750 shipped with Windows 11 Pro 22H2, but we updated it to 23H2 (and somehow entered the Windows Insider program) before starting our test. The System->About window confirms the update and that we have an FP750 PC powered by a 3.2 GHz AMD Ryzen 7 7735HS SoC with 32GB of RAM. HWiNFO64 provides some details about the AMD Ryzen 7 7735HS 8-core/16-thread […]

Sipeed Tang Primer 25K board features 23,040 Logic Cells for FPGA prototyping and development

Sipeed Tang Primer 25K Features 23,040 Logic Cells for Efficient FPGA Prototyping and Development

Sipeed has recently introduced the Tang Primer 25K, an FPGA board powered by Gowin Semi GW5A-LV25MG121 chip. This board features 23,040 LUTs, USB Host capability, and an optional SDRAM module that unlocks vintage gaming. We have previously covered many FPGA boards like Sipeed Tang Mega 138K Pro, Fudan Micro JFM7K325T, ILYGO T-FPGA, and many other development boards by Sipeed including the Sipeed Tang Nano 20K with a Gowin GW2A FPGA. You can check those out if interested. The Tang Primer 25K development board is divided into the 25K SoM Board and the 25K Dock Board together they offer a comprehensive set of features: GW5A-LV25MG121 specifications: 23040 LUT4 23040 Registers (FF) 28x 18×18 Multipliers 6x PLLs Memory/Storage: 64Mbit NOR Flash 180K Distributed S-SRAM 1008K B-SRAM (bits) 56 Number of B-SRAM I/O Interfaces: 3x PMOD 40-pin header 2x buttons 8x I/O banks 75x General IO MIPI IO – 4lane Data USB Ports: […]

Chatreey AM08 Pro (Ryzen 9 7940HS) mini PC review – Part 2: Windows 11 Pro

I checked out the hardware of the Chatreey AM08 Pro mini PC using an AMD Ryzen 9 7940HS CPU with an unboxing, a teardown, and the first boot in the first part of the review. Now it’s time for the 2nd part which will focus on Windows 11 Pro testing on the AM08 Pro. As previously said, I have received a version with a PCIe 3.0 NVMe SSD, which I have replaced with a 1TB Samsung 990 Pro NVMe SSD, so a Windows 11 reinstall was needed (I could also use Linux and dd one drive to another, but I had a Windows 11 ISO). Since the installation lacks a WiFi driver, I had to use the command oobe\BypassNRO to complete the installation. You can skip that step if you connect an Ethernet cable. The license was activated after connection to the Internet, so reinstallation is not a problem. Table […]

EXT-2.5GE-RK3588-RT is a quad 2.5GbE Ethernet expansion board for ROC-RK3588-RT SBC

Rockchip RK3588 SBC Seven Ethernet ports

In a recent article, we covered the ROC-RK3588-RT SBC, one of its main features was its three ethernet ports: one 2.5GbE and the other two standard ethernet ports. This setup made this board ideal for routers and firewalls. To enhance its capabilities, Firefly recently launched the EXT-2.5GE-RK3588-RT, a 2.5GbE Ethernet Expansion Board, which adds four more 2.5GbE ports to the ROC-RK3588-RT Rockchip RK3588 SBC. We’ve previously covered many SBCs, mini PCs, and motherboards from Firefly, such as their Rockchip RK3588 SBCs with 32GB RAM, the Firefly AIO-1684XQ motherboard, and the Firefly Station P3D mini PC. Feel free to check them out if you’re interested. While searching, I found limited documentation, but upon closer inspection, I discovered that the board uses the RTL8125BG IC for Ethernet control and the PI6C557-05 IC as a spectrum clock generator. There is also some kind of PMIC on the board recognizable by the big inductor, […]

Tillitis Tkey is an open-source RISC-V security key in a USB-C case

Tillitis’ TKey is a small, simple security key in a USB-C form factor, and described as a “new type of flexible USB security token” that is inspired by DICE (Device Identifier Composition Engine) and measured boot powered by a simple 32-bit RISC-V core, the PicoRV32, in a Lattice iCE40 UP5K FPGA. While we have covered hardware security modules in the past, this is the first security key we have seen that is based on an FPGA running a RISC-V core. The security token lacks persistent, onboard storage, unlike alternatives such as Yubikey Neo. Apps need to be loaded onto the key every time it is connected to a host device. It uses measured boot to generate a unique identifier for each application and is more secure than the alternatives since private keys are not stored on the device. Also, the hardware and software for the TKey are completely open-source for […]
