→Which Raspberry Pi to buy
|
== Now research how the various models relate to your needs ==
You can look up online what features are included in the various Pi models, and how they differ in power consumption, and cost. But your decision also needs to consider what you need. Here, I won't describe all the different models, but concentrate on just 2 for simplicity. The model Zero W is appealing as it has low power consumption, but has limited speed, it runs the various threads MX uses sequentially, and has limited interfaces for peripherals. The model Three B plus is appealing as it has medium power consumption, but can cope better with the multiple threads that MX starts, and has more interfaces built in, such as 4 USB 2 ports. Obviously, the model Four has more capability, but is less appealing as it also consumes more power.
*Raspberry Pi Three B Plus
** This faster Pi is NOT needed for running Cumulus MX, but it will cope better if you are asking MX to do lots of processing.
** Pi Three B Plus has a socket for an external power supply, Ethernet socket (supports wired link); a HDMI socket for audio/video to TV, or computer monitor; a standard audio socket for external microphone, or speakers; 4 standard USB 2 sockets for weather station, mouse, keyboard, USB stick, or other storage device; plus other connections (e.g. camera).
** This might be better if you also want to run a web server, or are on a remote site so you do want to be able to plug in a monitor and other peripherals.
== What else to buy ==
This obviously depends on your PI model and on your weather station connection type.
You may want to buy a case. A case specifically designed for your Pi model will have cut-outs in the right place for each interface connection and will have sufficient ventilation for the electrical components to not over-heat.
You may need a power supply.
You may need to buy connection leads. You may need a HDMI lead to connect your PI to your TV or a spare computer monitor. You may need a USB lead to connect to your weather station (the model Zero requires a micro USB, the model 3 requires a standard A end USB) which probably has a USB A end connection. If your weather station connects by Ethernet, you will need one lead to connect the station to the router and possibly another to connect the hub or router to the Pi.
