I don’t like that the pins are not labelled. I bought it to build my 5 year old daughter a Minecraft server. After three attempts. I pulled out my Xbox 360 and put it on that. I wanted it to play on her tablet on a server I controlled. I put the Raspberry Pi to better use. I added it to my Arduino I2C bus. May 2021, Raspbian released a 64-bit version of their OS for the Raspberry Pi. It included the 5.11 kernel. Arduino devices were ready to serve as I2C slaves. I bought the Canakit version with case, fan, etc. It is cool, you have a HDMI on it. I read I can build a NAS with it. I saw someone put a weather station on it with a battery pack. They put them in weather proof cases in the ocean. It comes in many types with different pin outs. You can get a them to build wearables to Ethernet/Wifi. My first Raspberry Pi was the newest 64-bit 8GB Raspberry Pi 4. I put a type 10 256GB SD card that was recommended in it. Check out my Raspberry Pi pages.
Pi has only 3.3V and digital pins on it. You can use a A-D converter and I can use the PWM pins to simulate analog.
It can do I2C but only at 3.3V. So you need a bi-directional logic level converter I2C bus. On one side Pi country 3.3V, ground, SDA, and SCL. On the other side Arduino country with 5V, Ground, SDA, and SCL
