Raspberry Pi 5-based portable AI learning platform features 41 modules, supports Arduino Nano, RPi Pico, and Micro:bit boards (Crownfunding)

CrowPi 3 is a Raspberry Pi 5-powered all-in-one portable AI learning and development platform with a 4.3-inch touchscreen display, plenty of plug-and-play electronic modules, a breadboard area, and support for Arduino Nano, Raspberry Pi Pico, and BBC Micro:bit MCU boards for expansion. It’s basically another take on the CrowPi 2 laptop based on the Raspberry Pi 4 with similar modules placed under the keyboard, but in a different form factor. The CrowPi 3 portable learning platform replaces the 11.6-inch Full HD display with a 4.3-inch display and does away with the keyboard, but is equipped with a more powerful Raspberry Pi 5 SBC capable of handling real-time AI tools such as ChatGPT and LLaMA (with smaller, distilled models). CrowPi 3 specifications: Main Board – Raspberry Pi 5 SBC Compatible MCU boards Arduino Nano boards BBC Micro:bit boards Raspberry Pi Pico boards Display – 4.3-inch IPS touchscreen display with 800×480 resolution […]

PicoEMP – A Raspberry Pi Pico-based open-source electromagnetic fault injector designed for EMFI testing and research

The PicoEMP is a compact, low-cost, open-source electromagnetic fault injector (EMFI) tool developed by Colin O’Flynn for researchers, hobbyists, and educators interested in hardware security. Unlike NewAE’s professional-grade ChipSHOUTER, PicoEMP is a bare-bones device designed to be safe, usable, and most importantly, affordable. Built around the Raspberry Pi Pico, this device generates high-voltage pulses using a transformer circuit (originally for photographic flash charging) to discharge energy from a low-ESR ceramic capacitor into a custom-made coil tip, which creates an electromagnetic field capable of injecting a little bit of power to the internals of the processors such as registers and SRAM. This can be exploited to flip bits and test the robustness of embedded systems against such attacks. ChipSHOUTER-PicoEMP specifications Main controller – Raspberry Pi Pico (RP2040 dual-core Arm Cortex-M0+ MCU @ up to 133 MHz) Purpose – Electromagnetic Fault Injection (EMFI) for testing embedded systems security Components High-voltage pulse generator circuit […]

Raspberry Pi Pico-sized RP2350 CAN development board features a clone of the MCP2515 CAN Bus controller

Waveshare has recently launched RP2350-CAN, a Raspberry Pi RP2350-powered CAN development board with onboard XL2515 CAN Bus controller and a SIT65HVD230 CAN transceiver. The board supports the CAN V2.0B protocol at up to 1 Mbps, and the XL2515 chip appears to be a clone of the popular Microchip MCP2515 CAN controller. The board includes the same 26 multi-function GPIO pins and USB-C port as found on the Raspberry Pi Pico 2. Other features include a DC-DC buck-boost converter (MP28164), BOOT and RESET buttons, a user LED, a selectable 120Ω CAN termination resistor, and CAN screw terminals. The CAN Bus board targets automotive, industrial control, and robotics applications. Waveshare RP2350 CAN specifications: SoC – Raspberry Pi RP2350A CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot OR Dual-core RISC-V Hazard3 @ 150 MHz Up to two cores can be used in any combination Memory – 520 KB on-chip SRAM […]

Openviro Axe PoE is an RP2040-based environmental sensor for server rooms and cabinets (Crowdfunding)

Openviro Axe PoE is a rack-mountable, open-source environmental sensor designed to measure the temperature and humidity (and air pressure) in server rooms or cabinets with electrical equipment. The device is based on a Raspberry Pi RP2040 board with Ethernet connectivity housed in an aluminum enclosure and equipped with two RJ12 connectors for Bosch BME280 sensors with an accuracy of +/- 0.5°C. It provides better results than sensors placed in a machine that may be impacted by the internal components’ heat dissipation. For instance, the two sensor inputs can be used to measure the temperature and humidity of the intake and exhaust in a server rack. Openviro Axe PoE specifications: Microcontroller – Raspberry Pi RP2040 dual Arm Cortex-M0+ @133 MHz with 264 KB SRAM Storage – 16 MB flash memory Network – 10/100Mbps Ethernet RJ45 port via LAN8710Ai Expansion – 2x RJ12 connector for THP Probes Misc – 3x Buttons Power […]

W6300-EVB-Pico2 board combines RP2350 MCU with WIZnet W6300 QSPI Ethernet controller for 80+ Mbps data rate

W6300-EVB-PICO2 board with Raspberry Pi RP23500 and W6300 QSPI Ethernet controller

WIZnet W6300-EVB-Pico2 is a development board that combines a Raspberry Pi RP2350 MCU with the company’s new W6300 QSPI Ethernet controller capable of 80+ Mbps data rates. WIZNet has made several 10/100Mbps Ethernet controllers over the years that connect to microcontrollers via SPI, but the speed is often limited to 15 to 70 Mbps due to a low SPI clock frequency and small buffers. The WIZNet W6300 Ethernet controller can deliver higher speed thanks to a 150MHz system clock, a QSPI interface with four data lines, 64KB SRAM, and 4KB TX/RX buffer for each of the 8 sockets. W6300 QSPI Ethernet controller W6300 features and specifications: Host Interface – High-speed QSPI (MODE 0/3), system bus with 2 address signals & 8-bit data Internal 32KB SRAM for Tx/ Rx buffers (64KB in total) 8x independent sockets with 64KB Memory 10BaseT / 10BaseTe / 100BaseTX Ethernet PHY Integrated Auto negotiation (Full and […]
