myBuddy 280 dual arm robot features Raspberry Pi 4 SBC and ESP32 controllers

Elephants Robotics myBuddy 280, aka myBuddy 280 Pi, is a dual-arm collaborative robot for education with a 7-inch display powered by Raspberry Pi 4 SBC, and also features three ESP32-based M5Stack core modules that help with the internal communication between the motors and the Raspberry Pi board. It builds upon the earlier myCobot 280 Pi robot with a single arm, with the same 280mm working range, but the new robot offers two arms, and a total of 13 degrees of freedom (DoF). The robot is also equipped with two 2MP HD cameras for computer vision, a standard 3.3V expansion I/O interface, a LEGO expansion interface, and can be fitted with a variety of adapters such as suction pumps, grippers, little hands (see below), etc… myBuddy 280 specifications: SBC – Raspberry Pi 4 (2GB or 4GB RAM) single board computer to control the display and communicate with the ESP32 modules IoT […]

CrowPi L Review – Part 2: Learn programming and electronics with a Raspberry Pi 4 laptop

CrowPi L review learn programming electronics

In the first part of our review of CrowPi L Raspberry Pi 4 laptop for education, we checked the hardware and accessories such as the CrowTail starter kit with various sensors and other electronics modules, and showed how to install or remove the Raspberry Pi 4 SBC from the laptop shell. I’ve now had more time to play with the educational software, so I’ll report my experience with the laptop when learning game design and hardware control with Letscode visual programming IDE, as well as the Python lessons for more advanced students. Reinstalling CrowPi OS image It’s the rainy season here in Thailand meaning it’s both hot and humid, and even though I’m not entirely sure it’s related, I recently had to reinstall Raspberry Pi OS on one of my Raspberry Pi with a corrupted SD card. It happened again with the CrowPi L after I left it in its […]

CrowPi L Raspberry Pi 4 laptop review – Part 1: Unboxing and teardown

CrowPi L Raspberry Pi Education Laptop Review

Elecrow CrowPi L is an 11.6-inch laptop shell based on Raspberry Pi 4 designed for STEM education with optional electronics modules and tutorials. That’s an evolution of the CrowPi 2 laptop I reviewed in 2020 with a thinner design and more flexible since the electronics modules are optional, so it can serve the market of people just wanting a Raspberry Pi 4 laptop. The company has sent me a full “CrowPi L Advanced Kit” for review with the CrowPi L laptop fitted with a Raspberry Pi 4, as well as the Crowtail Starter Kit for Raspberry Pi. CrowPi L Advanced Kit Unboxing Let’s check out the laptop package first. Since in this design, the laptop comes with a battery, and mine already had a Raspberry Pi 4 installed, I could just turn it on immediately. Accessories include a wireless mouse, a 12V/2A power supply (with USB Type-C plug… this should […]

STEPFPGA FPGA board is programmable with a Web IDE (Crowdfunding)

STEPFPGA MXO2Core miniature FPGA development board is based on Lattice MXO2-4000 FPGA, and designed for education with an easy-to-use Web IDE, instead of the more traditional tools that can be frustrating to use, and detailed tutorials. The board also comes with a 2-digit segment display, some LEDs, push buttons, and a 4-way DIP switch, as well as two rows of twenty pins for I/O expansion, and a USB Type-C port used for power, programming, or mass storage. STEPFPGA MXO2Core specifications: FPGA – Lattice Semi MachXO2 X02-4000 FPGA with 4320 LUTs Display – 2-digit segment display USB – 1x USB Type-C port for power, programming (UART), and mass storage Expansion – 2x 20-pin headers with up to 36x GPIOs, SPI, I2C, 3.3V, VBUS, GND; breadboard-compatible Misc – 2x RGB LEDs, 8x red LEDs, 4-way DIP switch, 4x push buttons Power Supply – 5V via a USB port Dimensions – Small four-layer […]

Arduino Braccio++ robotic arm is designed for high-school and university students

Arduino Education has just launched the Braccio++ robotic arm for advanced students in high school or at university in order to let them experiment with a 6 DOF, industrial, assembly line-inspired robot. The new robotic arm provides an upgrade to the Tinkerkit Braccio robot and has been designed to assist in teaching real-world manufacturing techniques,topics such as physics and robotics, and concepts like motions, forces, torque, gear ratio, stability, and weight of payload. The Arduino Braccio++ is comprised of the Braccio carrier board equipped with an Arduino Nano RP2040 Connect that controls six Arduino RS485 Smart Servo Motors with specifically four SR418D servo motors for the arm joints, and two SR312 servo motors for the claw. Four lessons and two projects are included in the kit, and it’s made for up to three students. Arduino says the new robotic arm is made of recycled and eco-friendly materials with the […]

E-Ink Digital Paper Tablet is about the size of an A4 or US Letter paper

While there’s now a bunch of devices with an e-paper display, be it tablets or eReaders, it’s harder to find a model that is about the size of A4 (297 x 210mm) or US letter (279 x 216mm) papers. E-Ink Digitial Paper Tablet solves this issue with an NXP i.MX 8M Mini-powered Android 9 tablet offering a 13.3-inch display (301.1 x 222.8mm), as well as a smaller 10.1-inch display, for business applications. Both digital paper tablets feature E-Ink Carta 1250 screen technology with a higher contrast ratio and faster refresh rate, come with a digital pen supported by Wacom’s battery-free EMR technology, and are said to last about three weeks per charge for light usage. E-ink digital paper tablet specifications: SoC – NXP i.MX 8M mini quad-core Cortex-A53 processor @ up to 1.8GHz Storage – 32 GB eMMC flash including 24GB for user data, or enough for about 10,000 typical […]

Maker Nano RP2040 offers Arduino Nano, Grove and Qwiic modules compatibility

Cytron Maker Nano RP2040 is board similar to Raspberry Pi Pico but with Arduino Nano form factor, a proper reset button, two RGB LEDs, single color LEDs for some GPIOs, a buzzer, as well as two Qwicc/STEMMA QT connectors that can also be used to connect Seeed Studio Grove modules using provided conversion cables. While the board mostly aims to be an Arduino Nano/Maker Nano upgrade, there are some notable differences with the I/O voltage being limited to 3.3V without 5V tolerance, and there are only four ADC inputs (A0 – A3) instead of eight on the Arduino Nano. Maker Nano RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Arm Cortex-M0+ microcontroller @ 125 MHz with 264KB internal RAM Storage – 2MB flash Audio – Piezo buzzer with mute switch Expansion 2x 15-pin headers with 22x GPIOs, 14x of which with LEDs,2x I2C, 2x UART, 2x SPI, 14x PWM, 4x […]
