Titan Mini is a smaller Renesas RA8P1-based Edge AI board for RT-Thread RTOS development

The Titan Mini is a smaller and somewhat cheaper version of the RA8P1 Titan board introduced in 2025 for AIoT applications and RT-Thread RTOS development. It still features a Renesas R7KA8P1 Cortex-M85/M33 microcontroller with an Arm Ethos-U55 NPU, but comes with lower-capacity memory and storage chips (32MB SDRAM and 8MB QSPI flash), drops the RJ45 Ethernet ports with a single FPC Ethernet connector, among other cost-saving measures. The only benefit I see besides the smaller size and slightly lower price is the presence of a microphone and a speaker connector for audio applications. Titan Mini specifications: SoC – Renesas RA8P1 (R7KA8P1) MCU cores Arm Cortex-M85 clocked at 1 GHz with Helium MVE (M-Profile Vector Extension) with 32KB I/D caches; 7300+ CoreMarks Arm Cortex-M33 clocked at 250 MHz with 32KB I/D caches GPU – D/AVE 2D drawing engine NPU – Arm Ethos-U55 NPU delivering 256 GOPS at 500 MHz Memory – […]

Linux 7.1 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 7.1 on LKML: So it’s only Sunday morning back home, but it’s Sunday afternoon where I am right now, so I’m doing the 7.1 release at the regular time – just not in the regular timezone. This obviously means that the merge window opens tomorrow, but I’ll be in yet another timezone by then, so timing will all be a bit irregular. Normally I try to front-load the merge window and do as much as possible the first few days – this time I’m not sure that will work out with my laptop and a couple of long flights without internet, but I’ve made sure that I have fetched the early pull requests (thank you – you know who you are), so I will be able to do some of it off-line. Anyway, possible slight hiccups in the merge window aside, the news today […]

Grinn ReneSOM-V2H is a tiny LGA SoM based on Renesas RZ/V2H processor for vision AI applications

Polish embedded systems company Grinn has recently introduced ReneSOM-V2H, a tiny vision AI SoM built around the Renesas RZ/V2H vision AI processor. Measuring just 42.6 x 37 mm, Grinn claims it is the world’s smallest module based on this specific Renesas MPU, and targets space-constrained Edge AI applications such as smart cameras, robotics, and industrial automation. The RZ/V2H SoC features a heterogeneous architecture with 4x Cortex-A55 cores, 2x Cortex-R8 cores, and 1x Cortex-M33 core, along with a DRP-AI3 accelerator with up to 8 TOPS. It supports LPDDR4 memory and eMMC storage, along with various connectivity options, including PCIe Gen3 (4-lane), USB 3.2, USB 2.0, and Gigabit Ethernet. It also provides four MIPI-CSI camera inputs and a MIPI-DSI display output for vision applications.

Renesas RA0E3 Arm Cortex-M23 MCU is a stripped-down RA0E1 for cost-sensitive applications

Back in 2024, Renesas first released the RA0E1, an ultra-low-power Cortex-M23 MCU designed for cost-sensitive applications, followed by the RA0E2, with extended temperature range support (-40°C to +125°C). The company has expanded its lineup with the RA0E3, a stripped-down version of the RA0E1 with less memory, fewer peripherals, and fewer GPIOs, designed for small and budget-focused applications for sensing, motor assist, safety, and basic system control. The MCU retains the same 32 MHz Arm Cortex-M23 (Armv8-M) core but now comes with 16KB flash and 2KB SRAM. It features an 8-channel 16-bit TAU timer, a 32-bit interval timer, a 10-bit ADC with a temperature sensor, a Data Transfer Controller, and serial interfaces including SPI, I²C, and UART (with LIN support). Additionally, it comes with up to 17 GPIOs, pull-ups, open-drain support, and built-in clock sources. It has an operating voltage range of 1.6V to 5.5V and supports −40°C to +125°C operation […]

Linux 6.19 Release – Main changes, Arm, RISC-V, and MIPS architectures

Linus Torvalds has just released Linux 6.19 on the Linux Kernel Mailing List (LKML): No big surprises anywhere last week, so 6.19 is out as expected – just as the US prepares to come to a complete standstill later today watching the latest batch of televised commercials. The betting man would expect them all to be AI-generated, but maybe some enterprising company decides to buck the trend? Doubtful, but there’s always a slight chance. But for anybody outside the US, maybe taking the newest kernel out for a spin instead is an option? I have more than three dozen pull requests for when the merge window opens tomorrow – thank you to all the early maintainers. And as people have mostly figured out, I’m getting to the point where I’m being confused by large numbers (almost running out of fingers and toes again), so the next kernel is going to […]
