Banana Pi BPI-M5 Amlogic S905X3 SBC in the Works

Banana Pi BPI-M5 is an upcoming Amlogic S905X3 SBC following the Raspberry Pi form factor, and that is pretty similar to Hardkernel ODROID-C4 launched earlier this year with the same quad-core Cortex-A55 processor. BPI-M5 will come with 4GB LPDDR4 RAM, 16GB eMMC flash, and offers four USB 3.0 ports, one Gigabit Ethernet port, and on HDMI 2.1 output port for 4K/8K video output. Banana Pi BPI-M5 preliminary specifications: SoC – Amlogic S905X3 quad-core Cortex-A55 processor @ up to 2.0 GHz with Mali-G31 MP2 GPU @ 650Mhz System Memory – 4GB LPDDR4 Storage – 16GB eMMC flash (option up to 64GB), MicroSD slot up to 2TB Video Output – HDMI 2.1 up to 4Kp60 with HDR, CEC, EDID Audio – 3.5mm audio jack, digital HDMI audio Connectivity – Gigabit Ethernet USB – 4x USB 3.0 ports via VL817 hub controller, 1x USB-C port (for power only?) Expansion – 40-pin Raspberry Pi header with 28x GPIO, UART, I2C, SPI, PWM, and power …

How to Take a Remote Screenshot in Raspberry Pi over SSH

I recently reviewed a Raspberry Pi 4 laptop with a custom interface that made it impractical to take screenshots directly on the device. So instead I had to take screenshots remotely over SSH. It’s quite easy to do. Most of the steps can be reproduced in other Linux systems, and are not specific to Raspberry Pi. Enable SSH in Raspberry Pi First, enable SSH either with sudo raspi-config in a terminal window and selecting 5. Interface Options, then P2 SSH… If for some reason, you don’t have access to the terminal, take out the MicroSD card from the Raspberry Pi board, and from a computer create a new empty file named “ssh” in the boot partition. Now provided you have the username and password for your board, you can connect to SSH with the IP address from a terminal: or a program like Putty. Taking a screenshot remotely You’re now ready to take a screenshot as follows: scrot is the …

Raspberry Pi Zero Inspired ATMegaZero Arduino Compatible Board Launched for $24.90

When we reported about ATMegaZero, an Arduino Leonardo compatible board following Raspberry Pi Zero form factor last July it was not available for sale just yet. The good news is that the Microchip ATmega32U4 board is now available on GroupGets for $24.99 plus shipping. The group buying campaign is expected to end around September 30th, and the boards will ship right after that. Here’s a reminder about ATMegaZero specifications: MCU – Microchip ATmega32U4 microcontroller running at 16MHz with 32KB Flash, 2.5KB SRAM, 1KB EEPROM (Arduino Leonardo compatible) Storage – MicroSD card Display – 32-pin OLED display port compatible with 30-pin SSD1306 and SSD1331 based displays Wireless Connectivity – 8-pin header for optional ESP8266 ESP-01(s) WiFi module Expansion – 40-pin Raspberry Pi-inspired GPIO header with UART, SPI, I2C, analog input signals Debugging & Programming – Micro USB port, 6-pin ICSP header Misc – 4x LEDs, reset push-button Power Supply – 5V via micro USB port Dimensions – 65 x 30mm Weight …

USBImager – A Lightweight Alternative to balenaEtcher

The common way to flash OS images to SD cards used to be “dd”. But you could potentially damage your system with a wrong command, it will not do verification after writing the firmware image, and it was not available in Windows, so people had to use Win32DiskImager, and last time I check it did not do verification either. So Etcher, now called balenaEtcher, became a popular cross-operating systems tool to flash images for Raspberry Pi and other SBCs. It’s easy to use and does verification after flashing. However, the binary is rather large at around 130 MB, and the company started to show sponsors to fund the development of the program, and this was not to the liking of everyone. During my review of CrowPi2 Raspberry Pi 4  laptop, I encountered an issue with balenaEtcher, which was quickly fixed once I updated the program to the latest version. But commenters pointed out there are now better tools including USBImager, …

CarPiHat Connects Raspberry Pi to your Car with Opto GPIO, CAN Bus, 12V Outputs

OpenAuto Pro software is a Raspberry Pi-based head-unit solution that brings various features to your car including Bluetooth hands-free Profile, music streaming, integrated media player, navigation via Android Auto, screen mirroring, rear camera support, and more. But TDJ realized he needs more than just a Raspberry Pi, touchscreen display, and OpenAuto Pro software to meet his requirements, so he designed CarPiHat add-on board for Raspberry Pi providing power supply, opto-isolated GPIOs, CAN Bus, and 12V outputs. CarPiHat key features and specifications: I/Os Dedicated reverse, illumination, and aux inputs, all opto-isolated. 2x opto-isolated general-purpose inputs (for a total of 5 inputs) 2x high-current, high side switched 12V outputs (@ 1A) for switching relays, lights, etc… 1x independent CAN bus port Broken out I2C bus. Broken out one-wire for temperature sensor, etc… Misc – Real-time clock to maintain system time across reboots, EEPROM for Raspberry Pi HAT compatibility Power Supply 12V – 5V buck converter with fuse and filtering to power the …

CrowPi2 Raspberry Pi 4 Education Laptop Review

I started my review of CrowPi2 Raspberry Pi 4 Learning Kit a while ago and at the time I showed content from the kit and its first boot. I’ve now spent more time with this very special Raspberry Pi 4 laptop and will focus this review on the education part, namely CrowPi2 software, but will also look at thermal cooling under stress with and without a fan, and try to install another Raspberry Pi compatible board inside the laptop shell. CrowPi2 Education Software It’s quite important to read the user manual before getting started as there are a few non-intuitive steps you may have to take. First I assume the wireless keyboard would just connect after pressing the power button, but it did not. The user manual explains the RF dongle is inside the mouse, and once you connect it you’ll be able to use the keyboard that has some battery charge out of the box, and can be charged …

PicoRio Linux RISC-V SBC is an Open Source Alternative to Raspberry Pi Board

There’s a lot of interest/hype around RISC-V, and low-cost boards such as Longan Nano or Maixduino are already available, but those are based on microcontroller-class chips, even though it’s possible to run Linux on Kendryte K210 RISC-V board, it comes without MMU, so it’s not for everyone. Linux capable RISC-V boards do exist but cost several hundred dollars or more with the likes of HiFive Unleashed and PolarFire SoC Icicle development kit. If only there was a RISC-V board similar to the Raspberry Pi board and with a similar price point… The good news is that the RISC-V International Open Source (RIOS) Laboratory is collaborating with Imagination technologies to bring PicoRio RISC-V SBC to market at a price point similar to Raspberry Pi. The PicoRio board was presented at the RISC-V Global Forum on September 3rd. I could not find the full presentation slides yet, but there are some screenshots here and there on Twitter giving us a few more …
