EVN Alpha is a LEGO-compatible robotics controller built around Raspberry Pi RP2040 MCU (Crowdfunding)

The EVN Alpha is a robotics project from a team based in Singapore and is aimed at roboticists seeking an advanced building platform beyond what LEGO Robotics kits offer. This robotics controller can be considered a spiritual successor to the LEGO MINDSTORMS EV3 intelligent brick. It runs on the Raspberry Pi RP2040 microcontroller with two Cortex M0+ cores running at a maximum clock speed of 133 MHz and 264KB of embedded SRAM and builds upon the rich software support available for the microcontroller. It features 64 LEGO Technic-compatible holes on five sides for easy installation into your projects and has 26 ports for I2C, UART, servos, EV3, and NXT motors. It is smaller volumetrically than the LEGO bricks and can be powered from two generic 18650 Lithium-ion cells rather than a proprietary solution (unlike the LEGO SPIKE Prime). The EVN Alpha was created as a “basecamp for students looking to […]

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, […]

Review of SONOFF SNZB-03P new Zigbee motion sensor with eWelink and Home Assistant

SONOFF continues to release new Zigbee products series including the wireless switches/buttons (SNZB-01P) and temperature and humidity sensors (SNZB-02P) that we reviewed last year. Today, we will review another new sensor, that is the Zigbee 3.0 motion sensor (SNZB-03P) and we’ll need a Zigbee Hub/Bridge/Dongle to receive Zigbee signals to make it work. The technology of this sensor remains PIR, which uses infrared waves similar to before. This is different from the Human Presence sensors that are gaining popularity, which use mmWave (millimeter wave, frequency 3-30GHz). Both types have their pros and cons. SONOFF has also recently released a Human Presence sensor, namely the SNZB-06P which we will review soon. The SONOFF SNZB-03P is suitable for applications where motion needs to be detected (staying standstill won’t work) and places where it is not feasible or practical to run power cables. The latter is advantageous compared to Human Presence sensors because […]

Quectel CC660D-LS IoT-NTN module is built for Skylo’s satellite network

Skylo Certified Quectel CC660D LS IoT NTN Chip

Quectel recently announced the launch of the Quectel CC660D-LS IoT-NTN module, created in partnership with Skylo. Designed for two-way IoT (Internet of Things) applications this model supports the latest 3GPP Release 17 standards for IoT over non-terrestrial networks (NTN). Additionally, It can operate on L-band (1 to 2 GHz), and S-band (2 to 4 GHz) frequencies, making it ideal for asset tracking, fleet management, and agricultural and maritime uses. Last year, we wrote about Qualcomm 212S and 9205S satellite modems which were also developed in collaboration with Skylo. Quectel CC660D-LS IoT-NTN Satellite Module Specifications: Module Type – NTN satellite communication module Compliance – Supports 3GPP Rel-17 IoT-NTN Frequency Bands – Operates on L-band (B255) and S-band (B256/23) Internet Protocols – Abundant embedded Internet service protocols Power Supply – Supports low voltage power supply from 2.2–3.6 V Power Consumption – Ultra-low power usage Sensitivity – Super-high sensitivity Temperature Range – Extended […]

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 […]
