40 Pin to Arduino Connector Hardware

Can any one please tell me any 40 pin to Arduino connector board.
I got this one : ARPI 600 - Raspberry Pi Expansion Board CrazyPi India , it does works but seems quiet old now.
Any alternative .
Thanks in advance !!

Seems like you are looking for a Raspberry Pi hat to Arduino UNO shield adapter. A quick Google search revealed something called gravity.

Ahh yes ,thanks , !! hope it is compatible with Raspberry PI 4B onwards as well.
