LilyGO T-PicoC3 board merges RP2040 & ESP32-C3, integrates color display

LilyGO T-PicoC3 is a small development board combining Raspberry Pi RP2040 dual-core microcontroller with ESP32-C3 RISC-V MCU to add WiFi and Bluetooth LE connectivity and adds a 1.14-inch color display to the mix, plus several I/Os. We had previously other designs merging ESP32 and RP2040 with UDOO KEY, Arduino Nano RP2040 Connect, or the Pico Wireless Pack among others, but as far as I know, the T-PicoC3 board is the first to use Raspberry Pi RP2040 and ESP32-C3 RISC-V processor. LilyGO T-Pico3 specifications: Microcontrollers Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with 264 KB of embedded SRAM Espressif Systems ESP32-C3 RISC-V processor with WiFi 4 and Bluetooth 5.0 LE connectivity Storage – 4MB SPI flash connected to RP2040 Display – 1.14-inch full-color IPS LCD Display (ST7789V SPI controller) with 240 x 135 resolution USB – USB Type-C port for power and programming (RP2040 / ESP32-C3) Expansion – 15-pin + 12-pin expansion […]

Turing Smart Screen – A low-cost 3.5-inch USB Type-C information display

“Turing Smart Screen” is a low-cost 3.5-inch USB-C display that connects to systems with a USB port, and works with Windows, Linux (including Raspberry Pi), MacOS, and other operating systems that support Python3. But contrary to my initial assumptions, it does not exactly act as a second monitor, and instead, it is an information display, originally designed to show resource utilization, e.g. CPU and memory usage, in Windows, and controlled through commands send to the USB port. Turing Smart Screen specifications: 3.5-inch IPS display with 480×320 resolution, portrait and landscape support MCU – WCH CH552T 8-bit E8051 core MCU for USB devices Host interface – USB Type-C interface Auto start on power on Dimensions Product: 85 x 55 x 8 mm Display area: 74 x 49 mm The manufacturer says it works with Windows only using its own software, and not AIDA64. The Windows software features functions to change the […]

Axzez Interceptor carrier board for RPi CM4 gets 8-port PoE+ board

The features-rich Axzez Interceptor carrier board for Raspberry Pi CM4 has gotten the Interceptor PoE board with eight PoE+ ports for connecting up to sixteen PoE IP cameras making it usable as a network video recorder. We first wrote about the Interceptor last January noting its impressive I/O capabilities with five SATA ports, four Gigabit Ethernet, two HDMI ports, RS-485 terminal block, and more. It also had two 40-pin FFC connectors “for future expansion”. Those connectors have now found a “meaning to life” with the Interceptor PoE board, as up to two can be connected to the FFC connectors. Some of the features of the new Interceptor PoE Board include: 8x fast PoE+ ethernet ports IEEE 802.3AF-2003 and 802.3AT-2009 compliance Each port has activity/link and status LEDs Input voltage range – 44-57V Optional 48V power boost that can support up to two Interceptor PoE+ boards (Powered from 12V ATX power […]

Ubuntu 22.04 LTS “Jammy Jellyfish” released

Canonical has just released Ubuntu 22.04 LTS “Jammy Jellyfish” right on schedule. The new version of the Linux operating system provides cloud confidential computing, a new real-time kernel for industrial applications, Arm optimization, support for Raspberry Pi SBCs, as well as support for enterprise Active Directory, PCI-DSS, HIPAA, FIPS, and FedRAMP compliance. Confidential Computing aims to improve data protection and privacy in public clouds without requiring any changes to existing application deployments, and Ubuntu 22.04 supports Azure Confidential VMs. Speaking about cloud computing, Canonical also says they optimized Ubuntu 22.04 LTS images for AWS Graviton for greater performance on Arm servers. The new real-time PREEMPT_RT kernel is currently in beta and available for both x86 and Aarch64 architectures. It is designed for telco (5G gateways) as well as other latency-sensitive applications such as industrial automation and robotics. Ubuntu 22.04 LTS is also the first long-term support release with Ubuntu Desktop […]

FOMO (Faster Objects, More Objects) enables real-time object detection on low-end embedded systems

FOMO used to stand for “Fear Of Missing Out” in my corner of the Internet, but Edge Impulse’s FOMO is completely different, as the “Faster Object, More Objects” model is designed to lower the footprint and improve the performance of object detection on resource-constrained embedded systems. The company says FOMO is 30x faster than MobileNet SSD and works on systems with less than 200K of RAM available. Edge Impulse explains the FOMO model provides a variant between basic image classification (e.g. is there a face in the image?) and more complex object detection (how many faces are in the image, if any, and where and what size are they?). That’s basically a simplified version of object detection where we’ll know the position of the objects in the image, but not their sizes. So instead of seeing the usual bounding box while the model is running, the face position will be […]
