You can't have just one, right?
I just discovered people are price gouging on Raspberry-Pi's up to $150!!
Years ago I bought my first one, the 2b+ for $45.
That's just the board, no SD-Card, no power-cable etc.
It had 1GB of RAM & Quad-core Broadcom BCM2836 900MHz 32-bit chip.
The CURRENT model, the 4b+ is a 64-bit Broadcom BCM2711 1500MHz with 2GB RAM, and includes WiFi & Bluetooth.
Also cost only $45 if you don't get the 4 or 8 GB's of RAM.
Don't pay gouge prices, they'll be available again.
I spent $1000 on a Radeon GPU that retailed for $800, and is now even cheaper because the availability is back.
Also I highly recommend buying the kits because you need to have a block that will deliver the right amount of power along with an micro-SD card. But most important is the mini fan and heat-sinks because the Pi-4 actually generates a considerable amount of heat.
The kit I bought was from CanaKit, and costs around US $115 I think?
Kit comes with:
- Raspberry Pi 4 Model B 4GB
- CanaKit 3.5A USB-C Power Supply with Noise Filter (UL Listed) specially designed for the Raspberry Pi 4 (5-foot cable)
- CanaKit Premium Black Case (High Gloss),
- Set of 3 Aluminum Heat Sinks
- CanaKit Fan
- Micro HDMI to HDMI Cable (6-foot cable)
- SanDisk 32GB Class 10 MicroSD Card, USB Card Reader Dongle
- CanaKit Quick-Start Guide
Bottom left is RaspberryPi 2b+ in an Adafruit case.
Bottom right is Raspberry-Pi 4b+. I have an ugly all-black CanaKit case for it, but haven't assembled it yet. I might actually get a nicer case.
Oh and the top board is the Pine64 RockPro64.
It uses the Rockchip RK3399 hexa-core. It's two ARM A72 cores + 4 A53 cores at 1800MHz and 4GB RAM. It costs a lot more than the Pi's, and the Pi-4 easily outperforms it since it has quad A72's, and lacks WIfi or Bluetooth.
Even worse it requires a REAL power block similar to a laptop, and just isn't nearly as good as a Pi-4b.
