Electronic Cats’ Flipper Add-On CANBus is a new add-on board for the Flipper Zero adding CAN bus communication to the popular wireless hacking tool. Built around the MCP2515 CAN controller chip this add-on card communicates with the Flipper Zero through an SPI interface. It allows users to sniff, send, and log CAN bus packets directly from the Flipper Zero, which means now you can analyze and manipulate CAN bus traffic for vehicle diagnostics, security research, and DIY projects. Previously we have seen Flipper Zero add an RP2040-powered video game module, and before that, we noted the developers launched their own app store with open-source apps. Additionally, we have written about Flipper Zero alternatives such as the M1 multitool so feel free to check those to know more about those solutions.

IP68-rated Rockchip RK3588 embedded mini PC works underwater
Mekotronics R58X-IP68 is a Rockchip RK3588-powered embedded mini PC with an IP68 ingress protection rating that makes it waterproof and even allows it to run submerged underwater. We’ve previously covered IP68 or IP67-rated hardware platforms like IoT gateways, thermal cameras, telemetry modules, and more. Those often rely on M12 or M8 connectors for waterproofness, but the Mekotronics R58X-IP68 relies on regular connectors housed in a waterproof socket and cable. Mekotronics R58X-IP68 specifications: SoC – Rockchip RK3588 CPU – Octa-core processor with four Cortex-A76 cores @ 2.4 GHz, four Cortex-A55 cores @ 1.8 GHz GPU – Arm Mali-G610 MP4 GPU VPU Video Decoder 8Kp60 H.265 VP9, AVS2 8Kp30 H.264 AVC/MVC 4Kp60 AV1 1080p60 MPEG-2, MPEG-1, VC-1, VP8 Video Encoder – Real-time H.265/H.264 video encoding up to 8Kp30, also usable as a multi-channel encoder in parallel (at lower resolution) AI Accelerator – 6 TOPS NPU System Memory – 4GB, 8GB, or 16GB […]
Arduino to switch from Arm Mbed to Zephyr RTOS
Following Arm’s decision to stop supporting Mbed from July 2026 onwards, Arduino has now decided to use Zephyr RTOS instead of Arm Mbed for Arduino boards that rely on the latter including Arduino GIGA, Arduino Nano 33 BLE, Arduino Nano RP2040 Connect, as well as Arduino PRO boards/solutions such as the Portenta, Nicla, and Opta families. Note that Arduino UNO, MKR, and Nano families are not impacted by the change since their Arduino Core implementation does not rely on Mbed. The change is not going to happen overnight as software development takes time, and Arduino plans to release the first beta based on ZephyrOS by the end of 2024. and a rollout for various boards starting in 2025 long before Arm Mbed is phased out for good. Arduino is not new to the Zephyr project as the company became a Silver member last year, and they were aware that Arm […]
Raspberry Pi RP2040-based Pico Video4 display board features 4 composite video outputs
The Pico Video4 Display is a Raspberry Pi RP2040-powered board that supports up to 4 analog composite video display interfaces with dedicated frame buffer memory accessible via SPI. The four video outputs are sent out through an RCA connector and a VGA DB15-HD connector that uses the red, green, and blue channels to create a composite video signal. The Pico Video4 Display is based on the Raspberry Pi RP2040 microcontroller chip and the VLSI VS23S040 four-megabit static RAM device with a video display controller that can output NTSC, PAL, and VGA video from the memory array. It provides the composite video outputs with a dedicated frame buffer and other hardware. This ensures that the RP2040’s limited processing power and memory are not hogged up in generating the video signal, leaving room for other major tasks. It has 8 inputs that are voltage-compatible to the input voltage, from 5V to 12 […]
The Blette Stick relies on Bluetooth 5.0 LE for off-grid messaging with up to 1.1km range
The Blette Stick is a Bluetooth 5.0 LE USB-C dongle designed to be attached to an Android smartphone in order to provide off-grid messaging and GPS coordinates sharing capabilities with a range of up to 1.1km in case WiFi and cellular networks are down. CNX Software readers may also be familiar with Meshtastic devices relying on WiFi to connect to the smartphone with Bluetooth and to other nodes using LoRaWAN to enable off-grid messaging while trekking or during emergencies. The Blettle Stick does something similar to the Meshtastic project but with Bluetooth LE long-range communication instead of Bluetooth+LoRaWAN. While the range will be shorter and limited to around 1km (line-of-sight), the plug-and-play design will make it easier to use for typical users who are not technically savvy. Blettle Stick specifications: SoC – Nordic Semi nRF52 Bluetooth 5.0 LE microcontroller (exact part number not specified, possibly nRF52840) Wireless – Bluetooth 5.0 […]
StackyFi ESP32-S3 board features camera connector, 40-pin GPIO header for Raspberry Pi HAT (Crowdfunding)
SB Components’ StackyFi is an ESP32-S3 WiFi and Bluetooth IoT board with a 40-pin GPIO header compatible with most Raspberry Pi HAT expansion boards and a camera connector for image capture to a microSD card or machine learning applications. The Raspberry Pi Zero-sized board also comes with two USB Type-C ports, one “native” and the other for serial debugging, an IMU sensor, an RGB LED, and Boot and Reset buttons. The board can be powered through one of the USB-C ports or a LiPo battery. It partially builds upon the earlier StackPi board with a Raspberry Pi RP2040 microcontroller. StackyFi specifications: Wireless module – ESP32-S3-WROOM-1 MCU – ESP32-S3 dual-core Tensilica LX7 up to 240 MHz with 512KB SRAM Memory – TBD PSRAM Storage – TBD flash Wireless – WiFi 4 and Bluetooth LE 5 PCB antenna Storage – MicroSD card Camera I/F – FPC connector that works with OV2640 camera […]
SONOFF SWV Review – A Zigbee Smart Water Valve tested with eWelink and Home Assistant
Today, we are going to test and review another new Zigbee product from SONOFF, the SONOFF Zigbee Smart Water Valve (SWV). This is the first water valve built by SONOFF. When it comes to devices related to water control, whether watering plants or opening and closing valves in tanks or pools, many people might be familiar with the SONOFF 4CHPro model, which is a WiFi smart switch that controls solenoid valves with DC or AC power (valve sold separately). The SONOFF SWV is an all-in-one device that integrates both valve control and IoT functionality in one. It is ideal for plant watering around the house or controlling water filling into pools or tanks. Besides being able to set schedules for opening and closing valves, it also has other interesting features. Let’s look at the details. Unboxing the SONOFF Zigbee Smart Water Valve Inside the box, you will find the valve […]
SparkFun RTK EVK offers GNSS with centimeter accuracy, WiFi, Bluetooth, 4G LTE Cat 1, and Ethernet connectivity
SparkFun RTK EVK is a fully-enclosed GNSS platform designed for fixed or mobile high-precision positioning and navigation applications with centimeter accuracy thanks to RTK (real-time kinematic) technology implemented with modules from u-blox. About two months ago, Sparkfun introduced the RTK Torch waterproof GNSS surveyor with Unicore UM980 GNSS module with RTK support, ESP32 for WiFi/Bluetooth, and an STM32WLE5C LoRa SoC. The SparkFun RTK EVK (evaluation kit) may drop LoRa connectivity, but it’s a more versatile platform with WiFi, Bluetooth, Ethernet, and LTE Cat 1 cellular connectivity, besides support for L1 + L2 RTK GNSS with L-Band correction.
