A modular smartphone is a smartphone designed for users to upgrade or replace components and modules without the need for resoldering or repair services.[1] The most important component is the main board, to which others such as cameras and batteries are attached.[1] Components can be obtained from open-source hardware stores.[2]
This design aims to reduce electronic waste, increase the phone's lifespan, and lower repair costs.[1] However, modular smartphones are generally bulkier and slower than their non-modular counterparts which may make them less attractive for most consumers.[3]
