A GOOD preparation is half the work done

When we play around with Arduino NANO, NodeMCU, ESP8266 and others it is important (and more comfortable) to make us life as less difficult as necessary. Therefore we will have a look on the How-To, using some helpful tools…

First of all it is a MUST to have “Breadboards” for connecting the components to the micro controller, they exist in different sizes and colours.

Item and quantity	Supplier and order number	Price
Mini Breadboard Kit for Arduino	AMAZON (DE): Mini Breadboard Kit für Arduino	6,99€
Breadboard 830 Pin Solderless Prototype PCB Board Kit	AMAZON (DE): Breadboard 830 Pin Solderless Prototype PCB Board Kit	9,99€
9 Volt Clips with connector	AMAZON (DE): 9 Volt Clips with connector 5 pieces	5,59€
Power Supply Module for Arduino Board	AMAZON (DE): Power Supply Module für Arduino Board 6 pieces	10,99€
Total:

Concerning the Power Supply Module for the Breadboard: it delivers 3,3 Volts AND 5 Volts. The 5 volts is the power Supply for Arduino, Nano, etc. and the 3,3 Volts is for OLEDs, RFID…

The advantage of the Power Supply for breadboard: once uploaded the sketch to the Arduino, Nano, ESP8266, etc. you can unplug the USB cable and connect a 9 volts battery (better an 9 Volts accumulator…) through the above mentioned 9 Volt Clips with connector. Now you can much more easily play around and move your prototype…

USB connector is for powering external devices (output only). Do not attempt to use it to power the MB-V2

Read carefully, please (important!!):

• YwRobot Breadboard Power Supply MB-V2
• …

The Power Supply has jumpers which one can switch from 3,3 V to 5 V. So on one side we place the jumper on 3,3 Volts and on the other side we place the jumper to 5 Volts, so that we have the two different voltages on two different power supply bus.

Practical example:

Please check the picture below where we use a RFID-RC522 and a Arduino NANO: the RFID-RC522 MUST get connected to the 3,3 Volts!! If connected on 5 Volts it would get damaged, actually fried!! The Arduino NANO is connected to the 5 Volts bus.

Let us have a look if everything is correct by measuring the voltages with a multimeter, here we go:
