You can now buy Nintendo Switch 2 motherboards from Chinese resellers directly from the production line for just $124 on local marketplaces like Goofish.

The Chinese resellers have shown images of a panelized PCB design, which is a manufacturing technique where multiple individual PCBs are arranged onto a single PCB during production. In the later stages, manufacturers and assemblers like Foxconn, separate or depanelize them.
The PCB that can now be purchased is identical to those in the official retail version of the Nintendo Switch 2 -- including the same market stamps which are usually applied during verification. Chinese marketplace variants are just missing some of the metallic shielding layers for important components, but that's about as close as we'll see to the official motherboards inside of the Nintendo Switch 2.
Nintendo Japan charges around $175 to repair or replace the PCB inside of the Switch 2, but this aftermarket option is definitely cheaper if you want to use third-party repair services. As Tom's Hardware points out, Nintendo could be using component-level ID verification to pair each part to a specific PCB, which could definitely be a road bump in aftermarket repairs.
The NVIDIA T239 processor inside is fabbed on the Samsung 8N process node, with an 8-core Arm-based CPU with 4M of shared L2 cache, and an Ampere GPU with 1536 CUDA cores. The CPU clocks are said to be around 1.1GHz to 1.5GHz with varying figures when the Nintendo Switch 2 is in docked mode, joined by a 128-bit memory interface using LPDDR5 memory. NVIDIA's new T239 processor inside of the Switch 2 supports NVIDIA DLSS upscaling technology, too.
