Know before you buy
No, this model is designed to be externally powered. It features four binding posts that allow you to connect your own power source to the breadboard.
The phosphor bronze spring clips are designed to securely hold wires with a diameter between 0.4 mm and 0.7 mm.
The PB-104M features 3220 tie-points, which provides enough space to accommodate up to 28 standard 16-pin ICs simultaneously.
It is rated for a maximum capacity of 1.5 A at 36 V. It is well-suited for most prototyping and low-voltage electronics, but you should ensure your project requirements stay within these limits.
No, the PB-104M arrives fully assembled. It is mounted on an aluminum back plate with rubber feet, so it is ready to use on your workbench right out of the box.
No, this model does not support interlocking. It is designed as a standalone, high-capacity unit.
