XIAO RP2350 is a tiny USB-C board based on Raspberry Pi RP2350 MCU

XIAO RP2350

The XIAO RP2350 is an upgrade to Seeed Studio’s XIAO RP2040 board with a more powerful Raspberry Pi RP2350 dual-core Cortex-M33 or dual-core RISC-V microcontroller found in the just-launched Raspberry Pi Pico 2 board. The new Raspberry Pi RP2350 USB-C board has the same form factor but adds eight more GPIOs on the bottom with pads for a total of 19 GPIOs, and we lose two LEDs for serial port connectivity. Most people will still be fine with the XIAO RP2040, but if you need a more powerful microcontroller, extra memory, a few extra GPIOs, and built-in security, then the XIAO RP2350 will be an improvement. XIAO RP2350 specifications: Microcontroller – Raspberry Pi RP2350 MCU CPU – Dual-core Arm Cortex-M33 processor @ 150MHz (Note: again RISC-V is not mentioned at all by Seeed Studio, like for the Cytron MOTION 2350 Pro board) Memory – 520KB internal RAM 8KB OTP Storage […]

$5 Raspberry Pi Pico 2 launched with Raspberry Pi RP2350 dual-core RISC-V or Arm Cortex-M33 microcontroller

Raspberry Pi Pico 2

The Raspberry Pi Pico 2 is an MCU development board based on the new Raspberry Pi RP2350 dual-core RISC-V or dual-core Cortex-M33 microcontroller with 520 KB on-chip SRAM, a 4MB flash, a micro USB port for power and programming and the same GPIO headers as the Raspberry Pi Pico board with an RP2040 dual-core Cortex-M0+ microcontroller with 264KB SRAM. The RP2350 embeds both an open-source Hazard3 RISC-V dual-core CPU and a dual-core Cortex-M33, but only one cluster can be used at a given time. Apart from the faster MCU cores and higher SRAM capacity, the RP2350 is about the same as the RP2040, albeit it also adds one extra PIO block bringing the total to three. One important new feature is built-in security when using Arm Cortex-M33 cores with Trustzone and other security features. Raspberry Pi RP2350 microcontroller Let’s have a closer look at the RP2350 microcontroller, before checking out […]

STMicro EVLDRIVE101-HPD 1.9-inch motor driver board can drive 750W BLDC motors

ST EVLDRIVE101 HPD 750W Brushless DC motors Driver

STMicroelectronics has recently revealed the reference design for “EVLDRIVE101-HPD” their homegrown BLDC motor driver board that can drive up to a 750W BLDC motor. This compact 50 mm (1.9-inch) circular PCB combines STDRIVE101 3-phase, triple half-bridge gate-driver IC with an STM32G0 microcontroller, which is responsible for driving three-phase brushless motors. The driver board supports various motor-control strategies, including trapezoidal and field-oriented control (FOC), with both sensor’ed and sensorless rotor-position detection. Additionally, it has a wide operating voltage range of 5.5V to 75V and includes STL220N6F7 60V STripFET F7 MOSFETs, which have very low Rds(on) for high efficiency. Other features of the board include ultra-low power consumption in sleep mode, a single-wire debug interface, direct firmware update capability, and protection mechanisms such as under-voltage lockout, overtemperature protection, and cross-conduction prevention. All these features make this board suitable for applications like hairdryers, handheld vacuums, power tools, fans, drones, robots, and industrial equipment […]

Building a workstation with Radxa ROCK 5 ITX (Arm) or Milk-V Jupiter (RISC-V) mini-ITX motherboard – Part 1: The hardware

Milk-V Jupiter ROCK 5 ITX mini ITX NAS enclosure

Radxa ROCK 5 ITX is a mini-ITX motherboard powered by a Rockchip RK3588 octa-core Cortex-A76/A55 processor, and the Shenzhen Milk-V Jupiter is another mini-ITX motherboard, but based on SpacemIT K1 octa-core 64-bit RISC-V processor instead. When Radxa contacted me about reviewing those, I thought it would be interesting to review a complete kit with a mini-ITX case since I had never built this type of system myself.  Yesterday, I was surprised to receive two large packages and thought maybe a company sent me a 3D printer or laser engraver kit, but instead, I got one package with the two Arm and RISC-V mini-ITX motherboards and another with a mini-ITX NAS enclosure with 6x SATA bays. Radxa ROCK 5 ITX unboxing Let’s look at the ROCK 5 ITX motherboard and accessories first. The motherboard ships with a rear panel and two screws for the M.2 module. The motherboard features the Rorkchip […]

STMicro ST4SIM-300 eSIM complies with SGP.32 GSMA eSIM Standard for IoT

ST4SIM 300 embedded SIM IC

STMicroelectronics has recently released the ST4SIM-300 eSIM, the first embedded SIM (eSIM) IC that complies with the new GSMA eSIM IoT Technical Specification (SGP.32). The chip is fully compliant with remote SIM provisioning of the GSMA eSIM IoT standards, so it works with 2G, 3G, 4G (LTE), CDMA, NB-IoT, and Cat-M networks. It is designed for small IoT devices and allows system operators to remotely program device subscriber identities over the air (OTA), making it a plug-and-play solution for seamless integration and management. Previously, we have written about Hologram’s IoT eSIM Chip that provides global connectivity and comes with 2FF, 3FF, 4FF, and Mff2- M2M form factors. We have also written about the Conexio Stratus Pro battery-powered nRF9161 development kit that supports eSIM as an option.

Panthor open-source driver achieves OpenGL ES 3.1 conformance with Arm Mali-G610 GPU (RK3588 SoC)

Panthor OpenGL ES 3.1 conformance Mali G610

Collabora has just announced that the Panthor open-source GPU kernel driver for third-generation Arm Valhall GPUs (Arm Mali-G310, Mali-G510, Mali-G610, and Mali-G710) has now achieved OpenGL ES 3.1 conformance with the Arm Mali-G610 GPU found in the Rockchip RK3588 SoC. Just a few days ago, Linux 6.10 was released with “support for Mali CSF-based GPUs found on recent Arm SoCs from Rockchip or Mediatek”, as expected from the earlier article entitled “Panthor open-source driver for Arm Mali-G310, Mali-G510, Mali-G610, and Mali-G710 GPUs to be part of Linux 6.10” published last March. But this did not say anything about the level of support for the Valhall GPU since it’s common for new hardware to be added with minimal support, and OpenGL ES 3.1 compliance means it’s ready for business… Collabora’s announcement explains this was tested on a Radxa Rock 5B single board computer: The conformance tests ran on a Rock5b board […]

Linux 6.10 Release – Notable changes, Arm, RISC-V, and MIPS architectures

Linux 6.10 Release Changelog

Linux Torvalds has announced the release of Linux 6.10 on LKML: So the final week was perhaps not quote as quiet as the preceding ones, which I don’t love – but it also wasn’t noisy enough to warrant an extra rc. And much of the noise this last week was bcachefs again (with netfs a close second), so it was all pretty compartmentalized. In fact, about a third of the patch for the last week was filesystem-related (there were also some btrfs latency fixes and other noise), which is unusual, but none of it looks particularly scary. Another third was drivers, and the rest is “random”. Anyway, this obviously means that the merge window for 6.11 opens up tomorrow. Let’s see how that goes, with much of Europe probably making ready for summer vacation. And the shortlog below is – as always – just the last week, not some kind […]
