These are all prototyping platforms, each suited to a different stage of development or type of project.

Solderless BreadBoard (e.g., BPS BB830): No soldering required. Components and wires are inserted into spring contacts. Fully reusable. Best for experimenting, testing circuit ideas, and learning. Connections are temporary and can be removed for troubleshooting or new projects.

StripBoard (e.g., BPS ST1, ST2, ST3U): Stripboards are PCBs with long copper strips running in one direction. You solder components in place and cut strips to break connections where needed. Stripboards are more permanent than a solderless breadboard and good for compact, durable builds where you don't want to order a custom PCB.

PadBoard (e.g., BPS PAD1, PAD2): PadBoards are PCBs with a grid of individual solder pads, typically one per hole. With a PadBoard there are no pre-connected strips. All connections are made with point-to-point wiring or wire wrapping. PadBoards offer maximum flexibility, you're not constrained by strip orientation. PadBoards can be more time-consuming than StripBoards but suit irregular layouts and customization.

Solderable PC BreadBoard (e.g., BPS SB830, SB404, BR1): Solderable PC breadboards are PCBs that have the same hole pattern and power rail layout as BPS’s standard solderless breadboard. This allows you to transfer your proven breadboard circuit directly to the PCB using the same circuit and component layout. You can solder the circuit you designed and tested on the breadboard onto the Solderable PCB for a permanent, reliable result. The Solderable PC BreadBoard is a common next step for small batch and field testing, after designing and testing on the solderless breadboard.
