What is it?

It is isolated IO module. Plugging-in Compatible to Raspberry pi header 40-pin header.

Why did you make it?

It is a DIY product for both tinkerers and non-tinkerers. It can be used monitor and control DC loads with voltage level from 12 V-24 V DC.

What makes it special?

It is optically isolated from Raspberry Pi. It is compatible with Raspberry Pi. Description: It is raspberry pi, compatible isolated input-output board. It can be easily plugged to Raspberry Pi's 40pin header by stacking up or optional ribbon cable with the suitable soldered header can be provided for external connection(it depends on the option you select while purchasing). It has 4 isolated digital inputs so that it can monitor 4 digital sensors simultaneously. It has 4 isolated digital outputs so that it can control 4 digital outputs like relays simultaneously.

We provide below options for purchase by selecting from the drop-down list available below the price details of product:

Option 1

Board with soldered suitable header compatible to stack up on Raspberry Pi. So that user can directly plug it on to Raspberry pi and use it for their application.

Option 2

Board with Male header and box header FRC to connect with Raspberry pi from externally instead of stack up. This will be useful where users cannot stack up on to Pi, they go for this option.

Option 3

Board without soldered any header. Will provide both male header and male/female combo header along with 40 pin FRC, So that user has to solder themselves the header whichever is suitable for their application.
