An inexpensive portable router was purchased online and disassembled with off-the-shelf components. Disassembly revealed the main router board with two antennae and one chip in the center. The main chip was an MIPS processor, and theres a specific model number silk screened onto the mainboard. The board has four unpopulated pin holes, which are typically called plated-through holes or annular rings We will just refer to them as plated through holes for this exercise.”]
