Great single board computers

Well, it's a another Pi. It's faster, they've fixed pretty much all previous shortcomings of previous models, most notably the absolutely critical tire bottleneck on the front (which made older versions very impractical to say the least). Interface bandwidth now makes sense, resources have grown, and key features have been added. HDMI is good. I had problems because of a bad cable. I'm kind of an electronics wizard, I have a very reputable and well stocked workshop that takes up half the floorโ€ฆ

Pros
  • 2-lane MIPI DSI/CSI ports for camera and display - 4-pin stereo audio and composite video port - Micro SD card slot for booting and saving the operating system
Cons
  • Annoys

Serious - not yet fixed - download errors.

RPI 4 is notorious for startup issues. If you have one of these POS, here is the PI website solution: Recovery If your Raspberry Pi 4 won't boot, the SPI EEPROM may be corrupted. To check, remove the SD card, unplug the device, and then plug it back in. If the green LED does not blink, this indicates that the EEPROM is corrupt. Raspberry Pi Imager offers an easy way to solve this problem by automatically preparing an SD card that flashes your Raspberry Pi 4's EEPROM: Locate an SD card that isโ€ฆ

Pros
  • Broadcom BCM2711 Quad-Core Cortex-A72 (ARM v8) 64-bit SoC @ 1.5 GHz --- 4 GB LPDDR4-2400 SDRAM
Cons
  • The list goes on.

Broken right out of the box.

I know sometimes you get a bad product. I'm sending mine back for a replacement or refund. It was dead when the box and board were slightly warped. The box was in good condition and showed no signs of transport or wear. It appears to have been warped prior to assembly as the USB and Ethernet ports are slightly curved in relation to the warped board. If this happened after reassembly they would match the circuit board. In any case, I will edit and increase the star rating after the board isโ€ฆ

Pros
  • 2.4GHz and 5.0GHz IEEE 802.11B/g/n/ac Wireless LAN, Bluetooth 5.0, Dual True Gigabit Ethernet
Cons
  • Unfashionable

Check your WiFi! Mine fails after 1 week

I loved it and have been building Plex servers with it . Well, in about a week the server will crash. Wi-Fi was not working and the system froze. I don't want to believe it was the nature of this article. The bottom of the box said 'Made in China' and it was a box of 14. I'm not a fan of the Element 14 brand as I've never been able to overclock them like the Pi's RS component boards. For some reason the board I received had a defect I think. After a week the wifi stopped working. It will notโ€ฆ

One of the 10 best computers of all time

Another one from the early 1980's and me have never shied away from criticizing any computing platform. I also try my best not to be religious; I'm writing this review on a MacBook Pro, but I also use Windows, Linux, Android and OpenBSD on a daily basis. However, I think the Raspberry Pi is one of the top 10 computers of all time. and that puts it on par with the likes of the original Macintosh, the original IBM PC, the Commodore 64, and the original iMac. Sometimes the best computers are theโ€ฆ

Pros
  • 2 USB 3.0 ports, 2 USB 2.0 ports --- 2 Micro HDMI ports supporting up to 4Kp60 video resolution
Cons
  • Expensive
