Key Applications & Projects

• Microcontroller Prototyping: Evaluate 28-pin micro-packaged controllers on a standard solderless breadboard.

• Logic Array Testing: Interface surface-mount shift registers or bus transceivers with Arduino or ESP32 development rigs.

• Firmware Development: Quickly break out SMD memory or signal processing chips for code verification.

Unlock New Capabilities (Project Evolution)

• Feature Upgrade: This board turns a fixed surface-mount chip into a removable DIP component, 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:

• 1 x SOP28 / SSOP28 to DIP28 Double-Sided Adapter PCB

FREQUENTLY ASKED QUESTIONS (FAQ)

1. 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.

2. What is the lead pitch for SOP28? The SOP side features a standard 1.27mm pitch.

3. What is the lead pitch for TSSOP28? The SSOP side features a 0.65mm pitch.

4. Will this fit a standard breadboard? Yes, it converts the SMD pins to standard 2.54mm spacing that fits all breadboards.

5. What are the dimensions of the PCB? The board measures 35.56mm in length and 20.32mm in width.

6. Does it come with header pins? No, 2.54mm male headers must be purchased separately.

7. Which side is for SOIC28? Use the 1.27mm pitch side.

8. Is it compatible with MSOP28? Yes, most MSOP28 chips with a 0.65mm pitch will fit the SSOP side.

9. Can I use this for chips with fewer than 28 pins? Yes, as long as the pitch matches, you can center smaller chips (like SOP20 or SOP24) on the pads.

10. Is the PCB material heat-resistant? Yes, the FR-4 material is rated for standard leaded or lead-free soldering temperatures.

11. How do I identify Pin 1? Pin 1 is indicated by a square pad on the silk screen.

12. 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.

13. What is the row spacing for the DIP output? It is standard 0.6-inch (15.24mm) wide spacing.

14. Are the pads pre-tinned? Yes, the pads feature high-quality plating for easy solder wetting.

15. What is the diameter of the output holes? They are standard 1mm holes designed for 2.54mm pin headers.

16. Can I use this with a DIP socket? Yes, once headers are attached, it can be plugged into a standard 28-pin wide DIP socket.

17. What color is the PCB? The board is standard green with white silk screening.

18. Can I reuse the board? Yes, if the component is desoldered carefully, the PCB can be reused.

19. What gauge wire fits the holes? Standard 22AWG solid wire or header pins are ideal.

20. Why are there two different side designs? Different IC standards use different pitches; this dual-sided board maximizes compatibility for the two most common 28-pin SMD standards.
