Free Tier - EC2 MySQL or RDS MySQL

Hi,
I have created the following setup:
a. an EC2 instance such that, I'm getting the "Amazon Linux AMI Test Page" via the Public Host Name of the Instance.
b. have configured Route53 to point a test domain to the instance and it is working.

I need to create a MySQL Database that is accessible from the PHP files in my EC2 instance.

https://aws.amazon.com/free/?all-free-tier.sort-by=item.additionalFields.SortRank&all-free-tier.sort-order=asc&awsf.Free%20Tier%20Types=categories%2312monthsfree&awsm.page-all-free-tier=1
As per Free Tier Details page, one RDS db.t2.micro database & one EC2 t2.micro instance is allowed.(additionally, in my EC2 dashboard, I also see a volume of 8GB present)

It is unclear whether, I can create & use database directly in my EC2 instance, while staying within Free tier restrictions.

In order to stay within Free Tier, Should I directly create the Database via SSH in EC2 or should I create a RDS MYSQL DB with Public IP.?
