Precision double-sided adapter board for narrow-body 16-pin ICs. Converts SOP16 (1.27mm pitch) and SSOP16 (0.65mm pitch) to standard 2.54mm DIP pitch.
Bridge the gap between modern SMD technology and breadboard prototyping. The V1 SOP16/SSOP16 to DIP16 Adapter is an essential utility for modern electronics design. As many advanced logic gates and microcontrollers are increasingly available only in surface-mount packages, this adapter allows you to use these components in traditional breadboard environments or DIY project enclosures without needing custom PCB fabrication for every test.
Probots™ ProSpec Grade Precision This adapter is Probots™ ProSpec Grade , featuring a high-quality FR-4 glass fiber substrate with precisely etched solder pads to ensure stable electrical connections. The Double-Sided Design provides maximum utility in a compact footprint:
Side A (Front): Features a 1.27mm lead pitch, compatible with common narrow-body SOP16, SO16, and SOIC16 packages.
Side B (Back): Features a 0.65mm lead pitch, compatible with smaller SSOP16, TSSOP16, and MSOP16 packages.
Output: Both sides route all 16 pins to standard 2.54mm (0.1") pitch holes, perfectly suited for standard male headers and breadboard insertion.
Board Dimensions: 21mm x 15.6mm
Material: High-quality FR-4 Glass Fiber
Pitch 1 (Front): 1.27mm (for SOP16/SOIC16)
Pitch 2 (Back): 0.65mm (for SSOP16/TSSOP16)
DIP Output Pitch: Standard 2.54mm (0.1 inch)
Pin Count: 16 Pins
Narrow-Body IC Testing: Optimized for narrow-body surface-mount packages to maintain a minimal footprint.
Component Evaluation: Test 16-pin SMD logic controllers or signal processors on a standard solderless breadboard.
Microcontroller Development: Break out 16-pin micro-packaged controllers for easy wiring to an Arduino or ESP32 development rig.
Unlock New Capabilities (Project Evolution)
Feature Upgrade: This board turns a fixed surface-mount chip into a modular plug-in unit, allowing for easy swapping between different prototype boards during the development phase.
Effort Level: Intermediate. Requires steady hands and basic SMD soldering techniques to mount the chip and the 2.54mm headers.
Package Includes:


Can I mount chips on both sides at once? No, the through-holes for the DIP headers are shared; you should only mount one component per board.
What is the lead pitch for SOP16? The SOP side features a standard 1.27mm pitch.
What is the lead pitch for TSSOP16? The SSOP side features a 0.65mm pitch.
Will this fit a standard breadboard? Yes, it converts the SMD pins to standard 2.54mm spacing that fits all breadboards.
What are the dimensions of the PCB? The board measures 21mm in length and 15.6mm in width.
Does it come with header pins? No, 2.54mm male headers must be purchased separately.
Which side is for SOIC16? Use the 1.27mm pitch side.
Is it compatible with MSOP16? Yes, MSOP16 chips with a 0.65mm pitch will fit the SSOP side.
Can I use this for chips with fewer than 16 pins? Yes, as long as the pitch matches, you can center smaller pin-count chips (like SOP8 or SOP14) on the pads.
Is the PCB material heat-resistant? Yes, the FR-4 material is rated for standard leaded or lead-free soldering temperatures.
How do I identify Pin 1? Pin 1 is indicated by a white triangle/dot or square pad on the silk screen.
Do I need a special iron for the 0.65mm side? A fine-tip soldering iron or hot air station is recommended for the smaller pitch.
Is this a "narrow-body" adapter? Yes, it is optimized for narrow SMD packages rather than wide-body versions.
Are the pads pre-tinned? Yes, the pads feature high-quality plating for easy solder wetting.
What is the diameter of the output holes? They are standard 1mm holes designed for 2.54mm pin headers.
Can I use this with a DIP socket? Yes, once headers are attached, it can be plugged into a standard 16-pin DIP socket.
What is the row spacing for the DIP output? It is standard 0.6-inch (15.24mm) spacing.
What color is the PCB? The board is standard green with white silk screening.
Can I reuse the board? Yes, if the component is desoldered carefully, the PCB can be reused.
Why are there two different side designs? Different IC standards use different pitches; this dual-sided board maximizes compatibility for the two most common 16-pin SMD standards.
