Banana Pi BPI-M7 – A thin Rockchip RK3588 SBC with dual 2.5GbE, M.2 NVMe storage, HDMI 2.1, and more

Banana Pi BPI-M7 SBC is powered by a Rockchip RK3588 SoC and comes with a low profile design that reminds me of boards from Khadas such as the Khadas Edge2 or VIM4 SBCs but with a few extra ports thanks to the larger form factor. The Banana Pi BPI-M7 single board computer is equipped with up to 32GB RAM and 128GB eMMC flash and features an M.2 2280 socket for one NVMe SSD, three display interfaces (HDMI, USB-C, MIPI DSI), two camera connectors, dual 2.5GbE, WiFi 6 and Bluetooth 5.2, a few USB ports, and a 40-pin GPIO header for expansion. Banana Pi BPI-M7 specifications: SoC – Rockchip RK3588 octa-core processor with CPU – 4x Cortex‑A76 cores @ up to 2.4 GHz, 4x Cortex‑A55 core @ 1.8 GHz GPU – Arm Mali-G610 MP4 “Odin” GPU Video decoder – 8Kp60 H.265, VP9, AVS2, 8Kp30 H.264 AVC/MVC, 4Kp60 AV1, 1080p60 MPEG-2/-1, VC-1, […]

SunFounder GalaxyRVR review – An Arduino programmable Mars Rover-like robot for education

SunFounder sent us a GalaxyRVR 6-wheel robot for review. It looks like NASA’s Mars Rover robots but targets the education market with an Arduino UNO R3 compatible board and an ESP32-CAM board for WiFi connectivity and video capture. The GalaxyRVR robot kit can transmit video signals over WiFi to explore planet Earth with your mobile device or tablet and the camera can be adjusted up and down thanks to a servo motor. The robot gets its power from a solar panel coupled with a battery and features sensors such as obstacle avoidance and ultrasonic modules. NASA’s Mars Rover exploration robots NASA is currently using the Perseverance rover, also known as Percy, as the latest planetary exploration robot to land on Mars. It is designed to explore the Jezero Crater as part of NASA’s Mars 2020 mission. In addition to its scientific instruments, Perseverance also carries Ingenuity, a small experimental Martian […]

Lichee Console 4A RISC-V devkit testing – Part 2: benchmarks and features in Debian 12

Sipeed Lichee Console 4A RISC-V devkit review

When checking out the hardware of the Lichee Console 4A portable RISC-V development terminal in the first part of the review, I noted that I had some troubles with the display that did not work properly. I did a little massage to “fix” the display, but unsurprisingly it ended up not being a long-term solution. So I had to open a case a few times and ended up breaking the wires to the fan… Each time I reassembled the device, the display only worked for a few seconds or minutes if at all. So I decided to test the system by keeping it open, as the display is working reliably that way. So I won’t be able to do a proper review testing the device on the go, but I still tested all features and benchmarked the T-Head TH1520 mini laptop with Debian 12, and will report my findings in […]

Arducam PiNSIGHT – A 4 TOPS AI camera board for the Raspberry Pi 5

Arducam PiNSIGHT Raspberry Pi 5 AI Camera module

Arducam PiNSIGHT is an AI camera board designed for the Raspberry Pi 5 equipped with a 12.3MP auto-focus module and an Intel Movidius Myriad X-powered SoM delivering up to 4 TOPS and supporting Intel OpenVINO deep learning models. The PiNSIGHT “AI Mate” is mounted underneath the Raspberry Pi 5 to which it is connected through a 15-cm USB-A to USB-C cable. The case is made of metal and acts as a heatsink, and Arducam told CNX Software it dissipates heat enough to cool down the Raspberry Pi 5, and they don’t think the active cooler is needed anymore. In other words, it also acts as a fanless enclosure albeit it’s not in contact with the CPU, so whether it’s enough probably depends on your use case… Arducam PiNSIGHT “AI Mate” specifications: AI accelerator – Luxonis OAK-SoM based on Intel Movidius Myriad X vision processing unit delivering up to 4 TOPS […]

Entry-level Industrial Shields ESP32 PLC 14 sells for 100 Euros

Boot & Work Corp has just introduced an entry-level PLC based on ESP32 wireless microcontroller with the “Industrial Shields ESP32 PLC 14” that comes with seven inputs and five outputs, as well as I2C, RS485, Ethernet, WiFi, and Bluetooth communication interfaces. We first covered “Industrial Shields” automation devices in 2017 when the company introduced panel PCs based on Banana Pi, Raspberry Pi, and Hummingboard (NXP i.MX 6) SBCs, as well as a few Arduino and Raspberry Pi PLCs. Boot & Work Corp then launched a Raspberry Pi 4-based PLC in 2021, and now the company has introduced the ESP32 PLC 14 part of a larger family of PLC devices as we’ll see further below. ESP32 PLC 14 specifications: Wireless module – ESP-WROOM-32U with ESP32 dual-core wireless microcontroller @ 240 MHz with 4MB SRAM, 4MB flash, 2MB PSRAM I/Os through terminal blocks 4x Digital Outputs 12/24 V DC (can also act […]

52Pi water cooling kit keeps the Raspberry Pi 5 SBC cool at 3.0 GHz

If you like fancy, but somewhat expensive and useless things, 52Pi’s water cooling kit for Raspberry Pi 5 SBC may be right up your alley and the over-engineered cooling solution sells for $120 on Seeed Studio where we discovered the kit. We’ve already seen the active cooler and official case do a decent job at cooling the Raspberry Pi 5, but several companies have also launched fanless cases for the latest Pi single board computer. Water cooling may only make sense when attempting to overclock the Raspberry Pi 5, and 52Pi claims the Broadcom BCM2712 processor can run a 3.0 GHz at a relatively cool temperature of 55°C. 52Pi water cooling kit content: Main water cooling unit with RGB LED fan, water tank, and base Water cooling radiator (that’s the orange thing on top of the Raspberry Pi) Black heatsink 2x Silicone hoses 12V/2A power adapter (US) 4x M2.5*10 hexagonal screws […]

Vivante NPU (found in Amlogic A311D) gets its open-source driver upstreamed to Mesa

The Teflon project is an open-source TensorFlow Lite delegate that currently supports VeriSilicon Vivante NPU and aims to support several other AI accelerators over time. The project has recently been upstreamed to Mesa meaning AI inference with open-source software will work out of the box in supported hardware once Mesa 24.1 is released in May 2024. Teflon relies on the Etnaviv open-source driver better known for working with Vivante GPUs found, for instance, in NXP i.MX processors, but Tomeu Vizoso also worked on implementing Vivante NPU support since May 2022 thanks to a sponsorship from Libre Computer and documented the development progress on this blog. The VeriSilicon Vivante “VIPNano-QI.7120” 5 TOPS NPU is found in the Amlogic A311D processor, and Tomeu tested Teflon with the Etnaviv NPU drive on both the Libre Computer AML-A311D-CC Alta and Khadas VIM3 single board computers with decent performance although still slower than with the […]
