HiLetgo3pcs NodeMCU GPIO Board ESP8266 NodeMCU Pin Out IO Out 1 into 2 for ESP8266 ESP-12E NodeMCU Development Board

I started out using breadboards for my ESP8266 projects. It was just the way I've always done it.Then I found these GPIO boards. The allow you to slip an jumper into the slot for a connection, or screw it in for a solid connection that stays in place.Sometimes I'll still need to use a breadboard if I need to share come pins with multiple devices, but I use the very small breadboards so my work are doesn't get too cumbersome.I also made some 3D Print boxes for them to slip into. The boxes have openings for the things I need to connect and where it is not "professional", it is solid and functional.

Use for development and LORA units

It works as intended to power my light strips.

Para un desarrollador de electrónica aplicada utilizando EPS6266 es todo lo que uno puede pedir

I ordered two packs of these with three in each pack. They came quickly and are well crafted. They make wiring up one of these ESP8266 project boards fast and simple becausge you don't have to do any soldering.The only reason I gave it 3 stars instead of 5 was because one of the project boards was for the ESP32 ( which is larger than a ESP 8266)

I've been quite happy with previous Hiletgo products, but this is an exception. Biggest complaint is poor quality soldering. Note the cold solder joints in photo, at top center. All three boards had cold joints. Not a big deal to reflow the solder, but quality on a through hole board should be much higher.
