ESP-01 Breadboard adapter

As you might know the pins on the ESP-01 module is very tight.ESP-01 adapter
This means that it can’t be mounted on the breadboard without shorting the two pin rows.

One solution is replace the straight pins with some angled pins.

Another solution and very commonly shown on the web is making a breadboard adapter. This way you can connect it across the middle of the breadboard without shorting the pin rows.

The adapter is made of two 1×4 or one 2×4 female header, two 1×4 male pins and a piece of prototyping pcb. my pcb has single islands and the soldering is shown on the photo. It works like a charm.
