Raspberry Pi 4 vs Pi 3 – What are the differences?

Raspberry Pi 4 vs Pi 3 B+

So now that the Raspberry Pi 4 model B has just been launched, it may be worth checking out the differences against the previous latest single board computer from the Raspberry Pi foundation, namely Raspberry Pi 3 model B+. Let’s get straight to the Raspberry Pi 4 vs Pi 3 B+ comparison table. Features/Specs Raspberry Pi 4B Raspberry Pi 3 B+ Release date 24th June 2019 14th March 2018 SoC Broadcom BCM2711 quad-core Cortex-A72 @ 1.5 GHz Broadcom BCM2837B0 quad-core Cortex-A53 @ 1.4 GHz GPU VideoCore VI with OpenGL ES 1.1, 2.0, 3.0 VideoCore IV with OpenGL ES 1.1, 2.0 Video Decode H.265 4Kp60, H.264 1080p60 H.264 & MPEG-4 1080p30 Video Encode H.264 1080p30 Memory 1GB, 2GB, or 4GB LPDDR4 1GB LPDDR2 Storage microSD card Video & Audio Output 2x micro HDMI ports up to 4Kp60 3.5mm AV port (composite + audio) MIPI DSI connector 1x HDMI 1.4 port up […]

Raspberry Pi 4 Features Broadcom BCM2711 Processor, Up to 4GB RAM

Raspberry Pi 4 SBC

Long expected, the Raspberry Pi 4 model B has finally launched, and it should not disappoint with a much more powerful Broadcom BCM2711 quad-core Cortex-A72 processor clocked at up to 1.5 GHz, 1 to 4GB LPDDR4, 4K H.265 video decoding and output support, a proper Gigabit Ethernet port, as well as USB 3.0 and 2.0 ports. Raspberry Pi 4 comes with all those extra features, but the form factor remains the same, and importantly the price is still $35 for the version with 1GB RAM, making Raspberry Pi alternatives suddenly much less interesting. Raspberry Pi 4 specifications: SoC – Broadcom BCM2711 quad-core Cortex-A72 (ARMv8) @ 1.5GHz with VideoCore VI GPU supporting OpenGL ES 3.0 graphics System Memory – 1GB, 2GB or 4GB LPDDR4 Storage – microSD card slot Video Output & Display I/F 2x micro HDMI ports up to 4Kp60 (Currently 1080p60 max. in dual-display configuration, although 2x 4Kp30 is […]

Raspberry Pi 3 Model B and Rock64 1GB SBCs Promotions

Raspberry Pi 3 Model B Free microSD Card

Ameridroid has some promotions for two of the most popular single board computers on the market. The Raspberry Pi 3 Model B (not B+) is now offered for $33.95, or $32.95 with CNXSUPPORTER1 coupon, with a free 16GB class 10 micro SD card pre-loaded with NOOBS. The company also discounted Rock64 board (1GB RAM model), with the same form factor as Raspberry Pi 3 Model B, but a faster Rockchip RK3328 processor, and high-speed interfaces like USB 3.0 and Gigabit Ethernet, making it one of the best alternatives to Raspberry Pi 3 board. You can now get it for $24.95, a discount of $5 compared to the normal price on Ameridroid. $24.95 also happens to be the price the board is sold on Pine64, but you may save on shipping depending on where you live. You’ll also be able to save a bit more by using one of the following […]

HKCam is a Raspberry Pi Zero W based DIY HomeKit IP Camera

HKCam Raspberry Pi HomeKit IP Cam

HKCam is an IP camera based on Raspberry Pi Zero W board and compatible with any HomeKit apps. The developer, Matthias Hochgatterer, did not make the hardware himself, and instead purchased a Raspberry Pi Zero W + camera kit sold for around $30 on Aliexpress. His main work was to design a 3D printed case and write the software running in the camera, as well as his own Home 3 smart home automation app for iOS compatible with HomeKit. The only hardware needed is the Raspberry Pi Zero W with a power supply, the official Raspberry Pi camera module with is flat cable, and a microSD card, so you could also get those locally instead of purchasing them from Aliexpress. The firmware is based on Raspbian, FFmpeg to access the camera stream, as well as hc, a lightweight framework to develop HomeKit accessories in Go. You’ll find the documentation, source […]

NODE Mini Server V2 is a Raspberry Pi Based Storage Server for the Decentralized Web

Node Mini Server V2 3D View

We’ve previously covered networked hard drive enclosures with Ethernet and/or WiFi running OpenWrt or Ubuntu that allows you to easily and fairly cheaply connect SATA drives to your local network with models such as Blueendless X3. NODE has done something similar with a DIY project featuring a Raspberry Pi 3 Model B+. NODE Mini Server V2 connects the popular SBC to a 2.5″ SATA hard drive over USB and is designed to build out the physical infrastructure for the decentralized web (e.g. IPFS) that would allow users to replace remote servers with nodes that they themselves own and operate. Having said that nothing would prevent you from using this as a simple NAS although performance will not be as optimal as the aforementioned products due to the lack of SATA or USB 3.0 interface, as well as having “Gigabit” Ethernet limited to 300 Mbps. Having said that the design could […]

E-ALE is a Free & Open Source Linux Training Program for Embedded Engineers

E-ALE official hardware kit

As I wrote about the Embedded Linux Conference 2019 schedule a few days ago, I found out one of talk planned to use E-ALE hardware kit for the session. I had never heard about this kit, but a quick search led me to e-ale.org website which explains E-ALE stands for Embedded Apprentice Linux Engineer. The training program is made for embedded engineers with experience designing firmware for microcontrollers, but now need to transition to embedded Linux. Training only happens in-person (no webinar) at existing Embedded Linux conferences and is comprised of 8 to 9 seminars over 2 to 3 days. It usually starts with a presentation on one subject, followed by lab time to practice the relevant learned skills. The training takes place on the E-ALE kit at each conference, but it does not refer to a specific hardware platform. In most conferences, the PocketBeagle and BaconBits add-on board are […]
