Raspberry Pi 4 Just Released: Faster CPU, More Memory, Dual HDMI Ports

The Raspberry Pi 4 was just released. This is the newest version of the Raspberry Pi and offers a better CPU and more memory than the Raspberry Pi 3, dual HDMI outputs, better USB and Ethernet performance, and will remain in production until January, 2026.

There are three varieties of the Raspberry Pi 4 — one with 1GB of RAM, one with 2GB, and one with 4GB of RAM — available for $35, $45, and $55, respectively. There’s a video for this Raspberry Pi launch, and all of the details are on the Raspberry Pi 4 website (link will be updated when available).

A Better CPU, Better Graphics, and More Memory

The CPU on the new and improved Raspberry Pi 4 is a significant upgrade. While the Raspberry Pi 3 featured a Broadcom BCM2837 SoC (4× ARM Cortex-A53 running at 1.2GHz) the new board has a Broadcom BCM2711 SoC (a quad-core Cortex-A72 running at 1.5GHz). The press literature says this provides desktop performance comparable to entry-level x86 systems.

Of note, the new Raspberry Pi 4 features not one but two HDMI ports, albeit in a micro HDMI format. This allows for dual-display support at up to 4k60p. Graphics power includes H.265 4k60 decode, H.264 1080p60 decode, 1080p30 encode, with support for OpenGL ES, 3.0 graphics. As with all Raspberry Pis, there’s a component video port as well tucked inside the audio port. The 2-lane MIPI DSI display port and 2-lane MIPI CSI camera port remain from the Raspberry Pi 3.

Smooth VU Meter Output on Two Tiny OLED Screens

Music can soothe the soul… or something like that, but adding visual feedback in the form of a VU meter, according Adam Ples, brings “a little magic to any audio equipment.” His setup allows you to add this effect without dealing with actual physical needles that bounce back and forth to the tunes, instead subbing in a pair of OLED modules with SSD1306 or SH1106 drivers.

Look inside the 3D-printed Mars home that NASA awarded $500,000

When you think of future Martian habitats, what do they look like? A squat, half buried, windowless dome? A glorified fallout shelter? Or … how about … this? This is Marsha. Designed by AI SpaceFactory. It has windows, multiple floors, private rooms, and even a skylight. But best of all? NASA loves it.

The rocket scientists and engineers at NASA are pros when it comes to landing robots on Mars. And they’re figuring out how to get humans there next. But when it comes to living on Mars? Well, they decided to ask the public for help. In the 2010s, NASA launched its 3-D Printed Habitat Challenge. Over the years, its held multiple stages of the phases of the challenge that started with virtual designs and has since progressed to full-fledged 3-D printed models.

ATOMIC Pi – A high power alternative to RPi

We’re RPi lovers, and the UP board is nice… but it’s about price and performance.  We feel there’s a market for a $34 Atom maker board.  Thus was born the ATOMIC Pi. 

  • Genuine Intel Atom x5-Z8350 quad core with 2M Cache. Runs up to 1.92GHz with a 480MHz GPU.  Eats RPi for dessert.  Beats some desktops.  
  • Loaded with memory: 2GB DDR3L-1600, 16GB eMMC, slot for SD expansion (up to 256Gb)
  • Full HDMI port with Intel HD Graphics & audio out
  • USB 3.0 and USB 2.0 ports
  • Fast dual band WiFI b/g/n 2.4 & 5GHz WiFi RT5572 IPX connectors on board
  • Bluetooth 4.0 CR8510 
  • Gigabit hardwired RJ45 Ethernet RTL8111G 
  • 9-axis inertial navigation sensor with compass BNO055 
  • TTL serial debug and expansion serial ports up to 3.6Mbps
  • Real time clock & battery
  • JST style connectors and a 26-pin header for power & GPIO. 
  • Runs on 5V. Typically 4-15 watts.
  • Legitimate licensed BIOS boots from SD, USB, or Ethernet. Linux comes preloaded… Yes, it’ll run Win10 64 bit.
  • Optional breakout shield with screw terminals for easy wiring
  • Well documented, find specs & files here. 
  • Our campaigns aren’t fancy, but we ship on schedule. Check out our feedback. 
  • What will you make with it?
