Description

RS485 / RS422 / RS232 Raspberry hat

Many devices still have serial data output.

In order to communicate these devices with a Rasperry, you needed a suitable hat.

This hat solves that problem.

This is a hat that uses the UART of the raspberry (Pins 8 and 10) pin number 12 (Gpio18) is used to define the direction of communication in RS485 mode.

In order to minimize the use of pins, the hat has some jumpers so that you can select the mode of use.

RS422 mode and RS232 mode only use UART pins.

Only one mode can be used at a time.

An upper 40-pin connector is also provided to dispose of the remaining pins of the GPIO.

All lines are protected with transient suppressor

The connection to the rasperry is made with softened lines to protect the port from the raspberry.
