Tiny Seeeduino XIAO board gets Raspberry Pi RP2040 MCU

Seeeduino XIAO is a tiny Arduino Zero compatible board with battery support that was launched last year with Microchip SAMD21G18 ARM Cortex-M0+ microcontroller at up to 48MHz. Seeed Studio has now launched the XIAO RP2040 board with the same form factor but upgrading to a more powerful Raspberry Pi RP2040 dual-core Cortex-M0+ microcontroller clocked at up to 133 MHz. XIAO RP2040 specifications: MCU – Raspberry Pi RP2040 dual-core Cortex M0+ up to 133 MHz, or even 252 MHz (48MHz default) with 264 kB SRAM Storage – 2MB SPI flash USB – 1x USB type C port for power and programming Expansion I/Os 2x 7-pin headers with 11x 4x analog inputs, 11x digital I/Os / PWM, 1x DAC, SPI, UART, and I2C; 2.54mm pitch 3.3V I/O voltage (not 5V tolerant) Misc – 1x user LED, power LED, 2x LEDs for serial port downloading, Reset Button/ Boot Button, RGB LED, SWD pads […]

PGA2040 is a Compact Raspberry Pi RP2040 Breakout Board by Pimoroni

Pimoroni is known for its development boards with a small form factor. PGA2040 is another compact breakout board featuring the Raspberry Pi  RP2040 microcontroller. The board comes in the form of a Pin Grid Array (PGA) with RP2040 at its center. The PGA allows the accommodation of 48 pins around the perimeter of SoC on such a small footprint. After seeing some of the advanced RP2040 boards featuring wireless functionalities in the past few months, such as the Arduino Nano RP2040 Connect board, Pico Wireless Carrier board, and Wio RP2040 Mini development board, the PGA2040 is a simple board with only necessary components, thus making it suitable for compact, simple applications. However, this increases the complexity and efforts from users for interfacing additional components to implement advanced applications. Talking more about the necessary components on the board, it comes with a Crystal Oscillator, 8MB of QSPI flash, and a 3V3 […]

RasPad 3 Review – Part 2: A Raspberry Pi 4 mini PC with integrated display

I started RasPad 3 review last week with an unboxing of the tablet shell for Raspberry Pi 4, together with assembly instructions, and a first boot after flashing Raspad OS to the system. In the first part of the review, I mentioned that I’d probably focus the remainder of the review on Ezblock Studio visual programming IDE, as the rest of the software is almost the same as using a standard Raspberry Pi 4, the other difference being the touchscreen-friendly RasPad launcher. But Sunfounder explained to me it would be hard to check out Ezblock as it’s designed to control robots and other hardware platforms, and requires an extra HAT (see Kickstarter campaign) to allow the Ezblock APP to connect through Bluetooth (it cannot be directly linked to Raspberry Pi through the built-in Bluetooth).  Here’s an example of a robot that is compatible with Ezblock Studio: Picar-X. Finally, I was […]

Radxa Zero SBC – A powerful quad-core alternative to Raspberry Pi Zero W

Radxa Zero SBC follows Raspberry Pi Zero W form factor, but thanks to an Amlogic S905Y2 quad-core Cortex-A53 processor clocked at up to 2.0 GHz offers much higher performance, which Radxa says corresponds to about 70% of Raspberry Pi 4 CPU performance. The tiny Arm Linux board comes with up to 4GB RAM, 16GB eMMC flash, and either AP6212 or AP6256 wireless module. plus all interfaces from Raspberry Pi Zero W, but with a twist as the mini HDMI port is replaced by a micro HDMI port, and USB-C ports are used instead of micro USB ports. Radxa Zero preliminary specifications: SoC – Amlogic S905Y2 quad-core Cortex-A53 processor @ up to 2.0 GHz with Arm Mali-G31 MP2 GPU System Memory – 512MB RAM, 1GB, 2GB, or 4GB LPDDR4 Storage – MicroSD slot, optional 8GB or 16GB eMMC flash Video Output – micro HDMI port up to 4Kp60 Connectivity Ampak AP6212 […]

Banana Pi BPI-M2 Pro compact Amlogic S905X3 SBC launched for $61

Banana Pi has already designed an Amlogic S905X3 SBC with Banana Pi BPI-M5 that closely follows Raspberry Pi 3 Model B form factor, but they’ve now launched a more compact model with Banana Pi BPI-M2 Pro that follow the design of the company’ earlier BPI-M2+ SBC powered by the good old Allwinner H3 processor. BPI-M2 Pro comes with 2GB RAM, 16GB eMMC storage, HDMI video output, Gigabit Ethernet, Wifi & Bluetooth connectivity, as well as two USB 3.0 ports. Banana Pi BPI-M2 Pro specifications: SoC – Amlogic S905X3 quad-core Cortex A55 @ up to 2.0 GHz with an Arm Mali-G31 GPU System Memory – 2GB LPDDR4 Storage – 16GB eMMC flash, microSD card slot Video & Audio Output – HDMI 2.1 up to 4Kp60 with HDR, CEC, EDID support Connectivity Gigabit Ethernet Dual-band 802.11 b/g/n/ac WiFi 5 1×1 and Bluetooth 4.2 via Realtek RTL8821CU module USB – 2x USB 3.0 […]

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 […]
