Due to the cost of reverse polish notation (RPN) calculators, I wanted to make the attempt at creating one myself.

A PCB kicad project to try to setup MSP430 as slave Modbus device using MAX481 as RS232 - RS485 converter, freemodbus on sourceforge
ModbusMSP430 is an open-source printed circuit board by penoud, from the penoud/ModbusMSP430 repository on GitHub, published under the MIT licence. It is a 2-layer board of 69.9 × 47 mm with 26 parts on 26 nets, routed with 227 tracks and 37 vias.
It is built around the MSP430G2553IPW20, MAX481EPA+ and RJ45, with the BSS138 among its other parts. Its parts include 9 connectors, 8 capacitors, 4 ICs, 3 resistors and 1 transistor. It belongs with the interfaces and adapters boards and the MSP430 boards of this library.

It measures 69.9 × 47 mm and has 2 copper layers, 1.6 mm thick.
26 parts, built around the MSP430G2553IPW20, MAX481EPA+, RJ45 and BSS138. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
From the penoud/ModbusMSP430 repository on GitHub, at the commit this page was made from: the board is ModbusMSP430.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
