About the RS-485-Transceiver breakout hardware design

RS-485-Transceiver breakout hardware design is an open source PCB design by SolderedElectronics, published on GitHub under the TAPR-OHL-1.0 license. It is a 2-layer board measuring 38 × 22 mm, with 14 components from 12 distinct parts.

Other key parts include the SN65176BDR. By type, the board carries 4 resistors, 2 jumpers, 2 relays, 2 capacitors, 1 IC and 1 diode.

It belongs with the rf & radio and dev boards & breakouts designs in this gallery.

From the project

Hardware design, BOM, gerbers and 3D files for RS-485-Transceiver-breakout designed by Soldered Electronics.

This module allows you to connect a Dasduino, or similar microcontroller, to a RS-485 communication protocol. The RS-485 is used to send data over long distances (up to 1200m) at 20Mbps and in high-noise environments, such as industrial. The module works on 5V and requires between 120μA and 500μA of current.
