​Convenient and Easy-to-use:

Solderless breadboard is convenient for the prototypes and circuit design experiment and other DIY projects.
Each row and columns has corresponding letters and numbers
Self-adhesive back tape makes it easy to stick on a platform, such as the Arduino prototype shield
With tight plug-in contacts, the components will sit well after assembly therefore there is no wobble.
Jumper wires are easy to insert into or remove from these breadboards.
With extension clips for simple and quick connecting with other boards.

​Thoughtful Product Features:

Perfect for Arduino shield prototyping and testing; can be applied in debugging without welding.
Fit for 21-26 AWG (0.4-0.7MM) wire. Comparing with breadboards of high AWG wire, Elegoo breadboards is of higher physical strength and lower resistance.
The solderless breadboards do not require soldering, therefore they are completely re-usable. This makes it easy to use for creating temporary prototypes and experimenting with circuit design which is a construction base for prototype of electronics.
Compatible with resistors, transistors, diodes, LEDS, capacitors and other types of electronic components

​Technical specification:

Matrix: 2 columns of 25+ & 25- point power panes down either side of the board, 2 columns of 30 lanes with two 5 point rows on each column across the center.
Input voltage: 6.5-12V (DC) or USB power supply
Output voltage: 3.3V/5V (Switchable)
Maximum output current: <700 mA
Two roads are of independent control and can be switched to 0V, 3.3V or 5V.
