About the Ps2 mouse to serial port adapter in a box PCB

Ps2 mouse to serial port adapter in a box is an open source AVR/Arduino PCB design by knightfox75, published on GitHub under the MIT license. It is a 2-layer board measuring 90 × 70 mm, with 24 components from 20 distinct parts.

Its main chip is the Arduino NANO v3, from the AVR/Arduino family. Other key parts include the 74LS00, L78L05 and L7805. By type, the board carries 6 capacitors, 5 resistors, 4 diodes, 3 ICs, 3 connectors and 1 module.

From the project

An Arduino-based converter for connecting a PS/2 mouse to a serial port.

1. Introducción -------------------------------------------------------------------------------- Los ratones con conexión DB9 para puerto serie cada vez son más difíciles de encontrar (y más caros), lo que puede suponer un problema si necesitamos emplear uno en un ordenador clásico que solo disponga del puerto serie para su conexión. Después de investigar unas horas, encontré varias opciones comerciales y un par de proyectos open source que, usando placas Arduino, permitían la conexión de un ratón PS/2, o USB compatible con el protocolo PS/2 a un puerto serie.
