The Zero-to-Pi3-Adapter (A) has onboard 4-ch USB Interface, Fast Ethernet Port and HDMI Port. The GPIO is on the Zero board, whose position is consistent with the actual height of the 3B series, so you can easily connect to the expansion boards used in 3B series boards or other development projects. Raspberry Pi Zero To 3B Adapter is an alternative for Raspberry Pi 3 Model B/B+, supporting Zero and Zero 2W.
Zero can be easily attached via specially designed connectors
Easily compatible with the interfaces of Raspberry Pi 3B / 3B+ boards
The same GPIO header height as 3B, easily connecting with 3B series HATs or development projects
Onboard 4-ch USB ports, compatible with USB 2.0 / 1.1 transmission
Onboard RTL8152B Ethernet chip, support 1-ch RJ45 Ethernet port, 10 / 100 M adaptive
