Coin cell-powered boards provide an easy way to test USB-C cables

The A2C caberQU and C2C caberQU boards enable the quick and easy testing of respectively USB-A to USB-C and USB-C to USB-C cables without external hardware. Powered by a CR2032 coin cell battery, the boards apply a voltage to all pins of a cable and measure which ones are connected to the other end. The results can be visualized immediately through various LEDS on the board. The C2C caberQU board comes with a dedicated LED for each of the 24 USB pins and the shield, and it’s possible to test the USB Type-C to USB Type-C cable in several different modes: USB 2.0/1.1 USB Power Delivery USB 3.0/3.1/3.2 Alternate Mode Debug Accessory Mode Audio Adapter Accessory Mode The A2C caberQU board has fewer pins and LEDS for testing USB-A to USB-C cables specifically, but it works the same way. Peter Traunmüller (aka petl) has shot a video showing one of […]

myCobot Pro 600 Raspberry Pi 4-based robot arm supports 600mm working range, up to 2kg payload

Elephant Robotics has launched its most advanced 6 DoF robot arm so far with the myCobot Pro 600 equipped with a Raspberry Pi 4 SBC, offering a maximum 600mm working range and support for up to 2kg payloads. We’ve covered Elephant Robotics’ myCobot robotic arms based on Raspberry Pi 4, ESP32, Jetson Nano, or Arduino previously, even reviewed the myCobot 280 Pi using both Python and visual programming, and the new Raspberry Pi 4-based myCobot Pro 600 provides about the same features but its much larger design enables it to be used on larger areas and handles heavier objects. myCobot Pro 600 specifications: SBC – Raspberry Pi 4 single board computer MCU – 240 MHz ESP32 dual-core microcontroller (600 DMIPS) with 520KB SRAM, Wi-Fi & dual-mode Bluetooth Video Output – 2x micro HDMI 2.0 ports Audio – 3.5mm audio jack, digital audio via HDMI Networking – Gigabit Ethernet, dual-band WiFi […]

Raspberry Pi Pico to Arduino Uno adapter relies on “FlexyPins” for castellated holes

Raspberry Pi Pico Arduino UNO adapter FlexyPins

Solder Party’s “Raspberry Pi Pico to Uno FlexyPin Adapter” transforms the Raspberry Pi Pico into an Arduino UNO without soldering the board directly or using headers, but instead relying on FlexyPins flexible pins to attach the Pico board to the adapter using its castellated holes. The end result is basically the same as for the WisdPi ArduPico board, except the Raspberry Pi Pico is soldered to the main PCB on the latter, but it can be easily removed from the Solder Party’s Uno adapter board to be replaced with another compatible model, e.g. Raspberry Pi Pico vs Pico W. The FlexyPins can be used with any board or module with castellated holes, but it’s obviously especially useful for castellated modules without through holes, for example, to easily program a bunch of ESP32 modules. You’ll first need to get a few FlexyPins as shown below. Then solder them to a compatible […]

SunFounder Zeus Car Kit review – A fun toy and Arduino learning tool

SunFounder Zeus Car Kit is an Arduino UNO and ESP32 Cam-based educational kit for children (and adults) that can be used to learn more about electronics, robotics, and programming. It’s a car comprised of four 6cm Mecanum wheels for omnidirectional motion and various sensors that can be controlled with an Android app enabling first-person view (FPV) thanks to the built-in camera. The company sent us a Zeus Car Kit for review and evaluation, and after assembly, we’ll use it in “Play Mode”, or in other words a toy that basically works out of the box, before checking out the “Programing Mode” and related Arduino tutorials to evaluate it’s educational potential. Zeus Car Kit Unboxing The kit comes in a nice retail package which highlights some of the capacities of the kit: FPV, Omnidrive, AI vision, compass, IR control, APP control, and RGB lights. The package itself contains four more boxes […]

SONOFF SNZB-01P/SNZB-02P Review – Zigbee wireless switch and temperature & humidity sensor tested with Home Assistant

SONOFF SNZB-01P & SNZB-02P Zigbee Review Home Assistant

SONOFF launched their 1st gen Zigbee product about a few years ago, and SONOFF have finally started to upgrade their Zigbee devices, and we received two Zigbee 3.0 devices from SONOFF for review, namely the SNZB-01P wireless switch and the SNZB-02P temperature and humidity Sensor. In a nutshell, their appearance looks more modern, with a round shape compared to the rectangular design of the previous models. Importantly, they are sturdier than before, and the battery capacity has increased almost 2x. As we anticipated, they can be used with other Zigbee Hubs from different brands as well. The main application used with both devices is still, of course, eWeLink, which many people are familiar with (a Zigbee Bridge Hub/Bridge is required). However, this review will focus more on the popular app called Home Assistant, which is widely used globally. SNZB-01P wireless switch After trying it out for a while and comparing […]
