Sonata v1.0 RISC-V platform combines AMD Artix-7 FPGA and Raspberry Pi RP2040 MCU, features CHERIoT technology for secure embedded systems

lowRISC has released Sonata v1.0, a stable platform developed under the Sunburst project. Designed for embedded systems engineers, Sonata supports CHERIoT technology, enabling features like compartmentalization and enhanced memory safety. It provides a reliable foundation for building secure embedded systems. CHERIoT is a security-focused technology built on lowRISC’s RISC-V Ibex core, based on CHERI research from the University of Cambridge and SRI International. It addresses memory safety issues like buffer overflows and use-after-free errors using CHERI’s capability-based architecture. The CHERIoT capability format includes permissions for memory access, object types for compartmentalization, and bounds to restrict accessible memory regions. These features enable scalable and efficient compartmentalization, making it suitable for securely running untrusted software in embedded systems. Sonata v1.0 leverages this architecture to isolate components like network stacks and kernels within the CHERIoT RTOS. The lowRISC Sonata v1.0 specifications: FPGA – AMD Xilinx Artix-7 (XC7A35T-1CSG324C) CPU – AMD MicroBlaze soft-core based on […]

Pico W5 is a Raspberry Pi Pico 2 W alternative with RP2350 MCU, dual-band WiFi 4, 8MB flash

The Pico W5 is a Raspberry Pi RP2350 development board providing an alternative to the official Raspberry Pi Pico 2 W with dual-band (2.4GHz/5GHz) WiFi 4 and Bluetooth 5.0 connectivity through a B&T BW16 wireless module. Besides dual-band WiFi, there are a few other small changes compared to the Raspberry Pi Pico 2 W, including a USB Type-C connector, a larger 8MB flash, and a Reset button. As far as I know, it’s the first RP2350 board with 5GHz WiFi, as other RP2350 boards with WiFi, such as the Challenger+ RP2350 WiFi6/BLE5 and Pimoroni Pico Plus 2 W, only support 2.4GHz WiFi. Pico W5 specifications: SoC – Raspberry Pi RP2350 CPU Dual-core Arm Cortex-M33 @ 150 MHz with Arm Trustzone, Secure boot and Dual-core RISC-V Hazard3 @ 150 MHz Only two cores can be used at any given time Memory – 520 KB on-chip SRAM Security 8KB of anti-fuse OTP […]

4D Systems Raspberry Pi RP2350 display modules come in touch and non-touch options for embedded applications

4D Systems, an Australian company specializing in intelligent display solutions, has released Raspberry Pi RP2350-powered display modules with touch and non-touch options. The display modules are available in eight different sizes from 2.4-inch to 9.0-inch and different resolutions from 240×320 up to 800×480 pixels. They are “Powered by Raspberry Pi”-certified and leverage the Raspberry Pi RP2350’s dual-core architecture and security features for “secure, professional-grade applications that require modern UI”. 4D Systems is well-known for its high-quality displays designed for developers looking to create sophisticated user interfaces in embedded systems. There are four touch panel options for each gen4-RP2350 display module: non-touch, resistive touch, capacitive touch, and capacitive touch with a cover lens bezel (CLB). The gen4-RP2350 series also features a 30-pin FPC/ZIF socket to fit a 0.5mm pitch FFC for connecting a motherboard or accessory board. We have already covered Waveshare’s RP2350-LCD-1.28 display module but the gen4-RP2350 display modules are […]

15 Euros Olimex RP2040pc Raspberry Pi RP2040 computer board supports Apple and Oric Atmos emulation

Olimex RP2040pc is an inexpensive “all-in-one” computer board based on a Raspberry Pi RP2040 MCU with support for Apple //e, Apple ][+, and Oric Atmos emulation through the Reload emulator. The board features an HDMI port, stereo audio, four USB ports, and two UEXT expansion connectors. It’s not quite the first RP2040 retrocomputing board from Olimex, as they introduced the RP2040-PICO-PC in 2021 with an HDMI port, a 3.5mm audio jack, and a microSD card slot before launching the Olimex NEO6502, which combines a MOS6502 MCU for Apple II, Oric, and Commodore 64 emulators with an RP2040 for HDMI/DVI video output and a few other things. The RP2040pc is similar to the latter, but with more ports and features, and everything is handled by the Raspberry Pi RP2040 microcontroller. Olimex RP2040pc specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU @ 133 MHz with 264 KB SRAM Storage – 16MB […]

SenseCAP Indicator – An ESP32-S3 and RP2040-based Meshtastic LoRa device with a 4-inch touchscreen display

The SenseCAP Indicator is a 4-inch capacitive touchscreen device designed for IoT connectivity and Meshtastic applications powered by Espressif Systems ESP32-S3 and Raspberry Pi RP2040 microcontrollers. It supports Wi-Fi (802.11b/g/n) and Bluetooth 5.0 LE connectivity, as well as LoRa using the Semtech SX1262 chip. The device also provides Grove connectors for expansion and a microSD slot supporting up to 32GB. Preloaded with Meshtastic firmware, the SenseCap Indicator is ready to function as a Meshtastic desktop or car node and can be reconfigured into a LoRaWAN Single-Channel Gateway. It features a 3.95-inch RGB touchscreen with 480×480 resolution, which is larger than most other Meshtastic solutions we’ve covered. Previously, we reviewed the SenseCAP Indicator D1Pro, which shares many features with the SenseCAP Indicator. However, the D1Pro integrates tVOC and CO2 sensors, along with an external Grove AHT20 TH sensor for precise temperature and humidity measurements. With real-time air quality monitoring from the […]
