Introduction

Bmana.jpg

The bmAna is a flexible and powerful analog inputs converter specifically designed to extend the spectrum of projects where the Arduino boards are used. It is a board that let you convert 0-10V, NTC/PTC and 0-20/4-20ma analog inputs to 0-5V (tension) with 10-bit resolution.

The design, engineering and production is completely made in Italy. IT flag.png

Bmini connection

In order to use this product with the Bmini you have to create a cable with a RJ45 connector and connect it to the Bmini's J8 connector plug and make sure to provide +5V and GND to the bmAna (pins named +5 and GND). Depending on which Arduino board you choose, you can have a different analog inputs mapping.

The following wiki pages explain in details the pins mapping:
