A side for pin pitch size 0.8mm, it can be used for most of the QFP, TQFP, LQFP, FQFP (compatible with 32pin~64pin) to 2.54mm DIP. B side for pin pitch size 0.5mm, it can be used for most of the QFP, TQFP, LQFP, FQFP (compatible with 32pin~100pin) to 2.54mm DIP.
SO/MSOP/TSSOP/SOIC/SOP8 to DIP package PCB Transfer Board is something you can use while prototyping for rapid circuit design and testing. You can also connect the legs of the DIP package Microcontrollers in it and It will work just fine or you can use the jumper wires for it too.
