Seen on eBay, a motherboard from the 2020 ARM development kit, the DTK.
The seller states that the board contains a development version of the M1 chip rather than an A12Z (visually, it’s quite surprising). They also mention that it has been drilled (like most boards seen for sale), but again, this is not very noticeable. However, as is often the case, the NAND chips have been desoldered.
