Step 1: Witty Cloud Module Adapter Board
I often experiment with a Witty-Cloud module.
The module consists of two interconnected boards. The lower one serves as a USB interface for programming. The upper contains the ESP8266 with micro-USB as power supply.
Step 2: Board Detail
What is in the detail on the two boards on it, is to be seen clearly in the scheme.
Step 3: Adapter
During the development phase of a program, the upper module is to be repeatedly disconnected and, e.g. to put on a breadboard with the periphery. To avoid this I have inserted an adapter in between.
This adapter is a double side PCB with female pin header. The pins of the left are connected 1 to 1. The pins in the right female connector as well. In the photos, the style and layout are good to see.
Step 4: Temperature / Humidity Logger
Now I can plug the peripherals directly and it separates the two boards. The figure shows the hardware for a temperature / humidity logger.
