Product Overview
Dual-sided layout converts surface-mount 28-pin integrated circuits into a standard breadboard-friendly DIP-28 footprint. One side routes a 0.65 mm pitch SSOP-28 or TSSOP-28 package out to through-hole pads, while the reverse accommodates a 1.27 mm pitch SOP-28 or SOIC-28 package. Both sides break out directly to two parallel 14-pin through-hole rows spaced at standard 0.6 in DIP pitch, fitting solderless breadboards, perfboards, and standard IC sockets.
Key Features
- Dual-sided layout accepts SSOP-28 (0.65 mm pitch) on Side A and SOP-28 (1.27 mm pitch) on Side B
- Breaks out to standard 28-pin DIP footprint with 2.54 mm (0.1 in) pin pitch and 15.24 mm (0.6 in) row spacing
- Pre-tinned surface pads and through-holes for direct hand soldering
- Silkscreen pin numbering 1 through 28 marked on both sides
- Dual mounting holes positioned off-center for mechanical fixturing
- FR-4 fiberglass substrate construction
Applications
- Soldering surface-mount microcontrollers or interface chips for breadboard prototyping
- Adapting SOIC-28 and SSOP-28 ICs into DIP sockets on legacy circuit boards
- Testing and evaluating SMD ICs without fabricating a dedicated test board
- Building one-off synthesizer modules, guitar pedals, and DIY microcontroller projects
Frequently Asked Questions
What row spacing does the DIP breakout use?
The through-hole rows are spaced at standard 0.6 inches (15.24 mm) across, matching standard wide-DIP sockets and spanning the center channel of standard breadboards.
Can both sides of the board be populated at the same time?
No. Both sides route their SMD pads to the exact same shared DIP through-holes, so only one SMD IC can be mounted per board.
What header pin spacing is required for the through-holes?
The through-holes accept standard 0.1-inch (2.54 mm) male pin headers or solid 22-24 AWG jumper wire.
More pieces cost less each - the price-break table on this page shows what each quantity costs.
Surface-mount parts make sense right up until you need to wire one into a breadboard. This little double-sided board solves the pitch problem cleanly so you can get back to building.
