1. Introduction

Raspberry Pi is a credit card sized development board, it can run the LINUX operation

system, and replay the desktop computer daily work ,such as word processing, spreadsheet, or

even games and media center. You can use Raspberry Pi to connect to television, monitors,

keyboards, mouse, and other devices. It can be developed as a device what we want.

ZDAUTO-MIO-Raspberry Pi is a I/O development board compatible with Raspberry Pi , it can

lead the Raspberry Pi’s I/O interface to the development board , and add the Smart Relay

module, switching value modules, analog quantity modules, pulsed quantity modules can be

choose to accessed the peripheral devices.

ZD-MIO-Raspberry Pi 3-KIT extension board is standard equipped with 4 M5S modules,

and the other 4 blank bases allow users to purchase M5S modules and insert them to realize

different functions.

2. Product feature

-The expansion board has eight M5S module bases, and customers can select modules

according to their functional requirements to realize the designed functions.

-External circuit access and switching voltages can be higher than the rated voltage on the

Raspberry PI;

-Select isolation module, realize circuit isolation, improve module security;

Type selection Tips:

1. The standard M5S-BID0324B1 module does not have the pull resistance function. If

you want to have a strong driving ability, it is recommended to choose the module

with the pull resistance internally, otherwise you must design the driver program in

the chip.

2. When the source module is not switched on, it is low; when switched on, it is

high.Therefore, it is recommended to select the source type module (such as BID.xx.

yyy.B1) for external drive with high power.

Conversely, the leakage module is high when not switched on, and low when

switched on.

Therefore, it is recommended to choose leaky module (such as BID.xx. yyy.A1) for

external drive with low power.

7. Practical application of expansion board

The I/O expansion board is equipped with 1 channel BI switch input, 2 channel BO switch

input and 1 channel AO analog output module. In addition, it is also optional to add 4 channels

M5S module.

GPIO point can be controlled based on raspberry PI platform and connected with the

corresponding signal pin of M5S switch input and output module, so as to connect with

external devices ， such as binary input devices (switches, knobs, limit switches, water level

switches, buttons) and binary output devices ( relay, contacts, solenoid valve, heating wire,

buzzer, motor). Similarly, it also can control the analog input devices, such as (Access

potentiometer, temperature sensor, pressure sensor),and the analog output devices(Control

motor speed, adjust furnace temperature, control tension, etc).
