Quartz64 Model B SBC revealed, Model A gets hit by production delays

Pine64 unveiled the Quartz64 SBC powered by Rockchip RK3566 processor a few months ago. More specifically they provided details about Quartz64 Model A at the time, a featured-rich variant with SATA, PCIe, multiple display outputs, etc… During the announcement, Pine64 also indicated a Raspberry Pi-sized Quartz Model B was in the works but did not have a prototype to showcase just yet. In the latest Pine64 April update, the community showcased the new board, reported software progress, and information about production delays for Model A. Quartz64 Model B Specifications: SoC – Rockchip RK3566 quad-core Cortex-A55 processor up to 1.8 GHz with Arm Mali-G52 GPU supporting OpenGL ES 1.1/2.0/3.2, OpenCL 2.0, Vulkan 1.1, 0.8 TOPS NPU for AI acceleration System Memory – 2GB to 8GB LPDDR4 Storage 128 Mbit SPI Flash optional eMMC module from 16GB up to 128GB capacity bootable SDHC/SDXC MicroSD card up to 2TB Video Output / Display […]

reTerminal – A Raspberry Pi CM4 based 5-inch HMI Terminal

Seeed Studio has just unveiled reTerminal HMI terminal that reminds me of the company’s Wio Terminal based on Microchip SAMD51 Arm Cortex-M4F microcontroller with a 2.4-inch display. But as we’ll look into the details, reTerminal is quite a different beast as a Linux-capable device powered by a Raspberry Pi CM4 module with up to 8GB RAM, equipped with a 5-inch capacitive touchscreen display, and supporting plenty of connectivity options from GIgabit Ethernet to WiFi to LoRaWAN. reTerminal specifications: SoM – Raspberry Pi Computer Module 4 with Broadcom BCM2711 quad-core Cortex-A72 processor @ 1.5 GHz, up to 8GB RAM, up to 32GB flash Display – 5-inch capacitive touchscreen display with 1280×720 resolution Video Output – Micro HDMI port up to 4Kp60 Camera I/F – 2-lane MIPI CSI inteface Connectivity Gigabit Ethernet with optional PoE support 802.11 b/g/n/ac WiFi and Bluetooth 5.0 BLE (on Raspberry Pi CM4 module) Optional 5G, 4G LTE, […]

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 – […]

Arducam Pico4ML Board – TinyML on Raspberry Pi RP2040 with QVGA Camera & Display

A few months ago, ArduCAM demonstrated person detection on Raspberry Pi Pico with Arducam camera using TensorFlow Lite, and later we noted more work was being performed to bring machine learning to RP2040 platforms, notably with the development of Arducam Pico4ML board with a built-in camera and display. At the time, i..e last month, all we had were some renders of the board, but now Arducam Pico4ML pre-orders have launched for $49.99 on UCTRONICS and Tindie stores. Shipping is scheduled to start at the end of the month, so let’s have a closer look. Arducam Pico4ML TinyML devkit specifications: Microcontroller – Raspberry Pi RP2040 dual-core Cortex-M0+ MCU with 264 KB of embedded SRAM Storage – 2MB SPI flash Display – 0.96-inch LCD SPI Display (ST7735) with 160 x 80 resolution Camera – HiMax HM01B0 QVGA camera (320×240 @ 60fps) Audio – Built-in microphone Sensor – IDK ICM-20948 9-axis IMU (gyroscope, […]

Arduino Core mbed 2.0 supports Raspberry Pi Pico & Arduino Nano RP2040 Connect

Last week, we noted and tried the unofficial Raspberry Pi Pico Arduino Core that works on RP2040 boards, including Raspberry Pi Pico. Everything was super early to set up and the blink sample worked just fine. But Arduino recently tweeted about the Arduino Core mbed 2.0 release that adds for Raspberry Pi RP2040 boards including Arduino Nano RP2040 Connect and Raspberry Pi Pico boards. Arduino first used mbed for their Arduino Nano 33 BLE board as they didn’t have an official Arduino core for the Nordic nRF52840 Cortex-M4 microcontroller, and it appears they’ve done the same for Raspberry Pi RP2040 whose mbed implementation itself relies on the C SDK. Let’s have a try, how hard can it be? We can find the release and changelog on Github with some instructions on the main Github. First, we can clone the repo in the sketchbook directory (See Arduino IDE’s preferences) which in […]

Olimex RP2040-PICO-PC “computer” to feature RP2040-Py Raspberry Pi Pico compatible module

We previously wrote it was possible to create a Raspberry Pi RP2040 board with HDMI using DVI and programmable IOs to output video up to 640×480 at 60 Hz with the microcontroller’s Cortex-M0+ cores clocked at 252 MHz. At the time, we also noted Olimex was working on such a board with RP2040-PICO-PC designed to create a small Raspberry Pi RP2040 computer with HDMI/DVI video output. The Bulgarian company has now manufactured the first prototype, but due to supply issues with the Raspberry Pi Pico board, they also designed their own RP2040-PICO module since they’ve got a reel of Raspberry Pi RP2040 microcontrollers. RP2040-PICO-PC small computer board Specifications: Support for Raspberry Pi Pico board Storage – MicroSD card Video Output – HDMI port with DVI signal (note no audio through this interface) Audio output – 3.5mm audio jack Expansion UEXT connector with UART, SPI, I2C, 3.3V, and GND to attach […]

DIY Raspberry Pi Compute Module 4 NAS supports up to four drives

We previously noted it was possible to build a Raspberry Pi CM4 NAS using Wiretrustee carrier board with a built-in Marvell 88SE9215 PCIe to SATA controller and four SATA connectors. But Mebs just created his own Raspberry Pi Compute Module 4 four-bay NAS with his own carrier board equipped with a PCIe socket used to insert a PCIe SATA card, as well as a neat 3D printed enclosure that took 6 days to print. This carrier board design is actually derived from the official Raspberry Pi CM4 IO board with only the interfaces needed for the NAS to make it smaller and fit within the width of a standard 3.5″ hard drive. It was also made as simple as possible because it was Mebs’ first PCB design. This leaves the board with Gigabit Ethernet, one HDMI port, a USB 2.0 port, the PCIe 2.0 socket, as well as some headers […]

Eyecam open-source webcam will make you feel spied on

Most people will use webcams connected to a computer or integrated into a laptop without thinking about the possibility of being spied on, but Eyecam will certainly raise awareness and make you feel like somebody is truly watching. The open-source webcam is shaped like a human eye and acts like one thanks to a Raspberry Pi camera and an Arduino board controlling six servos for eyeball, eyelids, and eyebrows movements. The project was conducted at Saarland University in Germany, and Eyecam looks amazingly realistic – and creepy – with the eyeball and eyelids moving, especially when face tracking is enabled, and expressions are possible with servos controlling the eyebrows. The webcam is comprised of 3D printed parts, a Raspberry Pi camera connect to Raspberry Pi Zero recognized as a USB webcam from the host, and an Arduino Leonardo Pro Micro to control the 6 servo motors. On the software side, […]
