RDL UNO-PI

QUICK OVERVIEW:
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.

1.External Analog pins(ADC).*

2.DC input 12v.

3.Power supply DC 12v.

4.DC-DC 12v-5v 2.5A.

5.UNO Header.

6.Serial communication port selection(jumper setting) .

7.External I2C.

8.8 bit Port selection (Raspberry Pi /Arduino/External data bus).

9.UNO Headers.

10.8bit Status LEDS.

11.8bit External I/O’s.

12.External SPI.

13.External Serial RX ,TX,GND.

* Works only with RDL UNO ATMEGA328  Stack on shields.
