Hello,
Yes, the
Raspberry Pi Zero W can handle an OSCam server with a small group of peers like the one you mentioned.
The
Raspberry Pi Zero W, despite its small size and cost, is quite capable. It features a 1GHz single-core CPU, 512MB RAM, mini HDMI and USB On-The-Go ports, and a 40-pin header. The "W" in its name denotes WiFi connectivity, which is an added advantage. Its processing power is more than sufficient for running an OSCam server for 7 to 10 peers, assuming ideal network conditions.
The most important aspect for running an OSCam server on the
Pi Zero W is your network. Oscam itself is fairly light on resources, but it needs a stable and reasonably fast network to perform well. The built-in WiFi of
Pi Zero W should be able to handle the load if you have a good WiFi connection.
However, do keep in mind that while the
Pi Zero W is capable of running an OSCam server, it's not the most powerful
Raspberry Pi model. If you plan to scale up your server in the future (more cards, more peers), you might need to consider a more powerful model, like the
Raspberry Pi 3 or 4.
Lastly, don't forget to use a good quality SD card for your
Pi as it will be constantly reading/writing data. A Class 10 card is recommended for its fast read/write speeds.
Hope this helps! Let us know if you have any more questions.
