"New" 3ds xl Motherboard Replacement Question

Hello all my 3ds broke and i had some questions about the repair process

i have a “new” 3ds xl Pikachu yellow edition and i was wondering if there was a certain motherboard model i need to buy or if any “new” 3ds motherboard would work

i would send it off to get repaired but i dont have a local electronics repair store near me unless someone knows of a trusty place i could send it off to otherwise i will repair it myself if possible
