A breadboard based on perfboard

Overview

Have you ever used breadboards and perforated boards? This PCB is a derivative of both!

The electrical connections are similar to a breadboard, but with the appearance of a perfboard. When using the improved perf board for circuit design, you can avoid wasting a lot of solder.

A PCB board as shown in the picture is about the size of two breadboards, with a total length and width of 99x99mm, and a spacing of 2.54mm. It can be used by inserting pin headers and female headers.

In order to facilitate power supply, the Type-C interface, power indicator light, power switch, and fuse are integrated into one. After the power is connected, the 4 rows in the middle will be powered, 2 rows of VCC, and 2 rows of GND.

The input voltage is sometimes not 5V. If you still want to apply voltage before the switch, you can apply power on demand to the VBUS and GND pads next to the Type-C interface.

In order to facilitate the power supply of the C2C interface, a 5.1k pull-down resistor is also connected to the CC1 pin. If not needed, there is no need to solder it.

Cute new work, light spray
