Prototyping Board Size & Hole Count Chart

Choose the right prototyping board based on size, hole spacing, and total hole count.

Board Type	Dimensions	Hole Count	Notes
Breadboard – Mini	3.5 cm × 4.5 cm	170 tie-points	Best for small sensor projects & modules
Breadboard – Half Size	8.3 cm × 5.5 cm	400 tie-points	Perfect for Arduino beginner circuits
Breadboard – Full Size	16.5 cm × 5.5 cm	830 tie-points	Large projects, power rails included
Perfboard / Dot PCB	Varies (5×7 cm, 7×9 cm, 10×15 cm)	≈ 200–800 holes	Solder-based prototyping
Zero PCB (Stripboard)	Common: 5×7 cm, 10×15 cm	≈ 200–900 holes	Copper strips for easy routing

Soldering Best Practices

Use the right temperature: 300–350°C is ideal for most PCBs and components.

Pre-tin both surfaces: Add a small amount of solder to the tip and pad for better flow.

Heat the joint, not the solder: Touch the pad + lead with the iron, then feed solder in.

Use flux: Flux ensures clean, oxidation-free joints and improves solder flow.

Keep the tip clean: Wipe the tip on a brass sponge or wet sponge frequently.

Inspect your joints: A good joint should look shiny and conical, not dull or cracked.

Top 5 Beginner Circuits to Try on a Breadboard

LED + Resistor Circuit: Learn polarity and basic current limiting.

Button Input Circuit: Build a pull-up or pull-down button circuit and read inputs with Arduino / ESP32.

Buzzer Beep Circuit: Create simple tones with a transistor & buzzer.

Light-Sensitive Night Lamp: Use an LDR + transistor to automatically turn on an LED in low light.

555 Timer LED Blinker: Classic beginner project using NE555 to blink LEDs with variable speed.

Prototyping Boards

Prototype boards make it easy to add custom circuits to your system. The prototype board has a set of standard 2.54mm pitch holes that can be used to permanently solder electronic components to the board. A prototype PCB boards is a critical step in the electronic product design process. prototype boards use traces to connect electronic components. Printed circuit boards are less expensive to manufacture than traditional circuit boards.

Frequently Asked Questions

1. What is PCB breadboard?

2. How do I make PCB prototype Boards?

3. Why it is important to use solderless breadboard in making a prototype circuit?

4. How does a prototyping board work?

Prototype boards make it easy to add custom circuits to your system. The prototype board has a set of standard 2.54mm pitch holes that can be used to permanently solder electronics to the board. They are used to run wires and some electronics through them to complete an electrical circuit.

5. What are the Types of Prototyping Boards?

Prototyping Boards are of 2 types: Breadboards and Vero boards. These two PCB boards such as Breadboards and Vero boards are both widely used in electronics development.
