You can simply prepare the iPad for a new owner by following this process:

What to do before you sell, give away or trade in your iPhone, iPad or iPod touch – Apple Support

This procedure will erase all data - and, critically, will remove the Activation Lock that will otherwise prevent reuse of the iPad. You should note that preparation of the iPad, wiping all data, will not impact your other devices.

However, if the iPad is an iPad2 - as perhaps suggested by the tags appended to your post - you need to be aware of the limitations of this iPad.

iPad2 can only be updated to iOS 9.3.5 (WiFi Only models) or iOS 9.3.6 (WiFi & Cellular models).

Apple ended update support for iPad2 in September 2016. iPad2 cannot be updated to iOS 10 or later major versions of iOS as the internal hardware does not meet the minimum technical requirements for new versions of iOS/iPadOS. This limitation cannot be bypassed; iPad2 is a 32-bit architecture device, whilst all recent versions of iOS/iPadOS are designed for 64-bit hardware platforms. iPad2 is obsolete.

Compatible Apps for your iPad are increasingly difficult to find - as third-party developers are increasingly dropping support for older versions of iOS preceding iOS11/12/13. As older versions of Apps are removed from the Apple App Store, you’ll not be able to (re)download or install them - which may severely limit the usefulness and utility of your iPad if you should you ever, as now, need reset or restore your iPad. As such, if the new owner wishes or needs to access most current Apps, requiring more recent versions of iOS, they’ll need to consider replacement of your iPad with a newer or current model.

Of current models, even the entry-level iPad8 has specifications and capabilities that will massively outperform a older model iPad - and is compatible with the vast majority of current Apps. Other models are more powerful still.

I hope this information provides helpful and succinct clarity as to your available options - and the limitations of your current iPad.

The iPad still has functionality, but with limited Apps now available, it’s utility will be limited. I described the limitations in order to set realistic expectations - so as to avoid later disappointment.
