Raspberry Pi Price And Components
Raspberry Pi Models:
Raspberry Pi 1 (A+) – This is the original raspberry pi system, and was the first one to come out in 2012 when the Raspberry Pi was initially launched. This system features an ARM 700MHz CPU, 256MB of RAM, one USB port, 40 GPIO pins, but lacking an Ethernet port. The A+ Model raspberry Pi goes for just $20 now.
Raspberry Pi 2 (Model B) – The Raspberry Pi 2 Model B is a much improved Raspberry Pi unit, with a much faster, now 900MHz quad core processor, 1GB of RAM, 4 USB ports, 40 GPIO pins, a full HDMI port built right in, an ethernet port, and a micro SD card slot. This version retails at just $25, and in most cases is worth the extra $5 upgrade from the Raspberry Pi 1 model A+.
Raspberry Pi 3 (Model B) – The Raspberry Pi 3 Model B is the newest and most up to date Raspberry Pi Module that currently exists. It goes for $35 and has almost identical specifications to the Raspberry Pi 2 model B, except this one has a slightly faster now 1.2GHz quad core processor, a step up from the 900Mhz processor the Pi 2 had, built in 802.11n Wireless N wifi, built in Bluetooth 4.1, and support for BLE (Bluetooth Low Energy)
Raspberry Pi Components:
Raspberry Pi GPS: The Raspberry Pi GPS module is a very useful add on for your raspberry Pi giving it GPS location abilities, useful for creating your own GPS system for your Raspberry Pi or for simply adding a GPS tracker to your current Raspberry Pi project in order to give it location tracking features. These will typically run you around $20-40 depending on the GPS module you get
Raspberry Pi Camera Module: The Raspberry Pi camera module is a really fun and useful module that you can purchase and plug into your Raspberry Pi in order to take pictures and videos with your Raspberry Pi device. This is a cool feature to tinker around with and can be very useful for projects you build with your Raspberry Pi that involve using a camera, such as turning the Raspberry Pi into a Photo booth or using the Raspberry Pi as a webcam. These typically range for around $30.
Raspberry Pi Button Modules: Raspberry Pi button modules are an excellent choice for adding additional buttons to your raspberry pi in order to program and utilize for projects you build with the Raspberry Pi. These can go from anywhere between a couple dollars to $20, depending on how many buttons you get.
