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 […]

CrowPi L is a $200 laptop shell for Raspberry Pi 4

Two years ago, we reviewed CrowPi 2 Raspberry Pi 4 laptop designed for STEM education with embedded electronics modules and Letscode software with step-by-step tutorials to learn Scratch and Python programming. I found it quite good, but many people were mostly interested in having a Raspberry Pi 4 laptop, and the price tag was a bit high at the time. That’s probably why Elecrow has now designed for CrowPi L laptop shell for Raspberry Pi 4 based on the CrowPi 2 but without all the electronics modules, and with a built-in battery to operate more like an actual laptop. CrowPi L laptop shell specifications: Compatible SBC’s – Raspberry Pi 4 Model B only Storage – Full-size SD card slot Display – 11.6-inch 1366×768 IPS screen (CrowPi 2 was 1920×1080) Video Output – HDMI output for external monitor Camera – 2MP camera Audio – Built-in microphone and stereo speaker; 3.5mm audio […]

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 […]

Wappsto:bit GO – An ESP32 board with plenty of sensors, Micro:bit compatibility (Crowdfunding)

Wappsto:bit GO is an ESP32 board compatible with BBC Micro:bit accessories thanks to a compatible edge connector, but adding WiFi to Bluetooth LE, and offering some extras compared to Elecrow Mbits ESP32-based BBC Micro:bit clone. The new board is notably equipped with a wider range of sensors including a light sensor, a magnetometer, and sound sensor beside the temperature sensor and accelerometer present in the original board, and it also exposes GPIO through a more traditional 2.54-pitch header to facilitate the integration of a wider variety of add-on boards. Wappsto:bit GO specifications: Wireless modules ESP32-WROOM-32E module with ESP32 dual-core microcontroller, 4MB flash, 2.4 GHz WiFi and Bluetooth LE connectivity, built-in PCB antenna Raytac MDBT50Q-512K Bluetooth 5.2 module based on nRF52833 with 512KB Flash MCU – NXP Kinetis KL2 Arm Cortex-M0+ microcontroller (MKL27Z256VFM4 ) with 256KB Flash (for USB port handling) Display – 25 LED matrix Sensors Temperature sensor, Light sensor […]
