Arduino

“Arduino is an open-source electronics prototyping platform based on flexible, easy-to-

use hardware and software. It's intended for artists, designers, hobbyists, and anyone interested in

creating interactive objects or environments.” - www.arduino.cc

Raspberry Pi

The Raspberry Pi is a credit-card sized computer that plugs into your TV and a keyboard.

It is a capable little computer which can be used in electronics projects, and for many of the

things that your desktop PC does, like spreadsheets, word-processing and games. It also plays

high-definition video. We want to see it being used by kids all over the world to learn how

computers work, how to manipulate the electronic world around them, and how to program

RDL UNO-PI

It's quite common practice for an hobbyist/Electronic enthusiasts building an application on

Raspberry Pi and Arduino stacked together. RDL UNO PI which reduces the circuit complexity

between Raspberry and Arduino , RPI and Arduino shields can be stacked easily onto UNO-PI

headers.

One can easily handle PWM and Analog inputs by stack on RDL ATmega328 board

programmed with Arduino IDE. Connectivity made easier by selectable jumper settings, enables

the connection switching between RPI(GPIO pins),UNO(D0-D7) and External data(IO0-IO7)

with Bi-Directional voltage level converter(3.3v-5v).On board DC-DC option provides stable

current up to 2.5A and 3.3v-5v for the required circuit.

Overview

This guide contains all information related to the Uno-Pi board.

The Uno-Pi PCB incorporates a standard Arduino (RDL-UNO ATMega328 standard header) and

standard Raspberry Pi B/B+ headers.

The PCB provides a three jumper settings (for boards port selection )

Raspberry Pi B/B+ to RDL-UNO ATMega328 and vice versa

Raspberry PI B/B+ to external data line

RDL-UNO ATMega328 to external data line

The PCB provides three jumper settings for serial communication

Raspberry Pi B/B+ to RDL-UNO ATMega328 and vice versa

Raspberry PI B/B+ to external data line

RDL-UNO ATMega328 to external data line

The PCB Front design contains RDL-UNO ATMega328 Development Board headers(pins) and

back design contains Raspberry Pi B/B+ header so that Rasp fusion board will connected

between RDL-UNO ATMega328 Development Board and Raspberry Pi B/B+.

Example for external data bus interface between raspberry pi and

atmega 328

With reference to above diagram

GPIO17 and GPIO18 pins(Raspberry Pi) is connected to digital data pins D2 and D3

(UNO Header) by setting two jumpers at JP1 and JP2

GPIO27 and GPIO22 pins (Raspberry Pi) is connected to External data pins IO2 and IO3

by setting two jumpers at JP2 and JP3

D4 and D5 pins (UNO Header) is connected to External data pins IO4 and IO5) by

setting two jumpers at JP3 and JP4
