CatsPi Industrial Lite RPi CM4 carrier board features GbE, RS485, Watchdog MCU

We’ve seen a fair deal of Raspberry Pi CM4 carrier boards, and here’s another one courtesy of QwaveSystems with CatsPi Industrial Lite board following Raspberry Pi SBC form factor/dimensions, and equipped with Gigabit Ethernet, RS485, USB ports, as well as a watchdog MCU among other interfaces and features. Contrary to what the name implies, CatsPi Industrial Lite only works with Raspberry Pi CM4 with eMMC flash, but not the CM4 Lite module since there’s no MicroSD card on the baseboard. It’s not the first Raspberry Pi Compute Module 4 carrier board with RS485, however, as we previously covered CM Hunter also including CAN and 1-wire interfaces, but QwaveSystems’ solution is more compact and mostly mechanically compatible with Raspberry Pi model B SBC’s. CatsPi Industrial Lite board specifications: Compatible SoMs – Raspberry Pi CM4 with eMMC flash only Video Output – Micro HDMI port Connectivity – Gigabit Ethernet, optional 802.11b/g/n/ac WiFi […]

Rock Pi 4 Plus SBC gets Rockchip OP1 processor, eMMC flash pre-loaded with Twister OS Armbian

The low-cost Rock Pi 4 SBC was unveiled in 2018 with a Rockchip RK3399 processor, up to 4GB RAM, and Raspberry Pi 3 form factor. Rock Pi 4 Plus builds on the relatively popular single board computer with an upgrade to Rockchip OP1 processor, which is a higher performance RK3399 SoC typically used in Chromebooks and ASUS Tinker Board 2. The new board also adds 16 to 128 GB eMMC flash, instead of relying on an optional eMMC module, and will come pre-loaded with Twister OS Armbian lightweight desktop OS based upon Armbian Focal 20.04.1 LTS (aarch64) for Rockchip RK3399-based SBCs. Four variants of Rock Pi 4 Plus share most of the same specifications: SoC – Rockchip OP1 big.LITTLE hexa-core processor with  2x Arm Cortex-A72 @ up to 2.0 GHz, 4x Cortex-A53 @ up to 1.4 GHz, a Mali-T864 GPU with support OpenGL ES1.1/2.0/3.0/3.1, OpenVG1.1, OpenCL, DX11, and AFBC, and […]

Flashback: This is what the Raspberry Pi USB Computer looked like 10 years ago

The first Raspberry Pi single board computer was officially launched on February 29, 2012. Raspberry Pi Model B included a Broadcom BCM2835 ARM11 processor with 256 RAM, an HDMI port, and the familiar form factor we know today. But the very first time I wrote about the board was on May 8, 2011, exactly ten years ago, with a post entitled “25 USD ARM11 Linux Computer” showing the prototype of Raspberry Pi USB Computer that looks nothing like what was launched the next year. This just looked like a stick with an HDMI port on one hand and a USB port at the other. We did not even know it was based on a Broadcom processor at the time. Those were the preliminary specifications: CPU – 700MHz ARM11 processor GPU – OpenGL ES 2.0 capable Memory – 128MB of SDRAM Storage – SD/MMC/SDIO memory card slot Video & Audio Outputs […]

Antmicro ARVSOM offers StarFive JH71x0 RISC-V processor, Raspberry Pi CM4 compatibility

The Linux capable BeagleV SBC, now called “BeagleV Starlight”, was announced last January with a StarFive JH7100/JH7110 64-bit RISC-V processor, and developers and beta users have just started to get their hand on the board in recent days. But there’s another StarFive JH71x0 hardware in the works with Antmicro ARVSOM. The system-in-module will feature the dual-core RISC-V processor, and be compatible with Raspberry Pi CM4, and by extension Antmicro’s Scalenode server-oriented baseboard. The company did not provide the complete specifications for the module, but based on public information available, Antmicro ARVSOM should feature the following: SoC – StarFive JH7100 Vision SoC: RISC-V U74 dual-core with 2MB L2 cache @ 1.5 GHz Vision DSP Tensilica-VP6 for computing vision NVDLA Engine 1 core (configuration 2048 MACs @ 800MHz  – 3.5 TOPS) Neural Network Engine (1024MACs @ 500MHz – 1 TOPS) VPU – H.264/H.265 decoder up to 4Kp60, dual-stream decoding up to 2Kp30 […]

MPi4 NEC MediaPlayer Kit slot-in card powers 4K digital signage displays with Raspberry Pi CM4

NEC Display Solutions has been integrating Raspberry Pi Compute Modules into commercial displays used for digital signage and presentation platforms for over 5 years now. The company, now called Sharp NEC Display Solutions, has launched a new Intel Smart Display Module (SDM)-like slot-in card based on Raspberry Pi Compute Module 4 called “MPi4 NEC MediaPlayer Kit” and designed as an entry-level card alternative to the company’s Intel SDM slot-in cards designed for NEC large format 4K displays. MPi4 NEC MediaPlayer Kit specifications: SoM – Raspberry Pi Compute Module 4 “NEC Edition” with SoC – Broadcom BCM2711 quad-core Arm Cortex 72 @ 1.5GHz, VideoCore IV GPU with OpenGL ES 3.0 graphics,  H.265 (HEVC) up to 4Kp60 decode, H.264 up to 1080p60 decode, 1080p30 encode System Memory – 4GB LPDDR2 SDRAM Storage – 32 GB eMMC flash Dimensions – 55 × 40 × 4.7 mm Interface Board for Raspberry Pi Compute Module […]

Terminal Block modules for Raspberry Pi Pico come with screw or DIN rail mounting option

if you’d like to use terminal blocks with your Raspberry Pi Pico, or compatible board,  instead of soldering wires to the MCU board, HCDC’s Terminal Block Breakout Module may meet your requirements with variants for either screw or DIN rail mounting. Description/specifications: PCB mount Terminal Block with 5 mm pitch, 7mm strip length, M2.5 screws – Wire range 28AWG ~ 12AWG / 2.5mm square. FR-4 fiber glass PCB, dual copper layers. Mounting options Screw version – “Taiwan high-quality” fireproof nylon material mount carrier (“not China low-quality carrier”). DIN rail version – “High-quality Taiwan” DINKLE fireproof nylon material DIN rail mount carrier (“not China low-quality carrier”); supports 35mm wide rail. I have not mentioned it in the introduction, but after reading the specifications, it appears (Xuken) HCDC may be based in Taiwan. 🙂 The company explains its Terminal Block Breakout Module for Raspberry Pi Pico is best suited to industrial control, […]

PiMod Zero for Raspberry Pi Zero SBC broadcasts video to your older NTSC TV (Crowdfunding)

Playing retro games or watching older movies on your Raspberry Pi Zero board over a modern digital video interface like HDMI clearly ruins the experience! 😉 While it should be possible to use to 2-pin reserved for video composite on the Raspberry Pi Zero to connect to an old TV, PiMod Zero HAT allows you to get back that retro feeling even with TVs lacking RCA composite and audio inputs by broadcasting video over VHF to older NTSC compatible televisions. PiMod Zero specifications: Operating frequency – VHF channels 2 and 3 (55.25 MHz and 61.25 MHz) Broadcast format – NTSC RF output power – 0.005 mW Impedance – 75 Ω Supply voltage – 5 V Power draw – 100 mW Dimensions – pHAT form factor The expansion board supports both color and B&W video, as well as audio. There were already solutions to achieve the same results, but Isotope Engineering […]

The Tiniest Raspberry Pi RP2040 Boards – Tiny 2040 & Adafruit QT Py RP2040

The Raspberry Pi Pico officially board for RP2040 MCU has a lot of free space on the PCB. So when third parties made their own board they either added features like camera, display, and sensors as found on like on Arducam Pico4ML board, while others “cut the fat” to the minimum. Some of the tiniest Raspberry Pi RP2040 boards are Pimoroni Tiny 2040 & Adafruit QT Py RP2040, both of which come with the dual-core Cortex-M0+ MCU, a USB-C port, two buttons, some I/O ports, and not much else. Tiny 2040 Pimoroni Tiny 2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller@ up to 133Mhz with 264kB of SRAM Storage – 8MB QSPI flash USB – USB Type-C port for power, data, and programming I/Os – 2x 8-pin castellated and through holes for 12 I/Os pins including 4x analog inputs, SPI, I2C, UART, 5V, 3.3V, and GND Debugging – […]
