Overview
Max232 is an open-source printed circuit board by BASM, from the BASM/MAX-UART repository on GitHub. It is a 2-layer board with 14 parts on 20 nets, routed with 122 tracks and 8 vias.
It is built around the MAX232N. Its parts include 6 connectors, 5 capacitors, 2 transistors and 1 IC.
Main components
1README
README.mdMAX-UART
Stage: Stable
A board having convertor RX,TX and DTR,RTS pins. The board was designed special for programming Atmel AVR and NXP ARM microcontrollers.
Board used max3232 chip in SO16, used MOSFET transistors for DTR, RTS level convert.
DTR and RTS used for Reset (ARM and AVR) and POI_3(for ARM).
Programs for programming is:
- AVR -- Self written from avr_boot project. See https://github.com/BASM/avr_boot project.
- ARM -- lpc21isp. Project http://sourceforge.net/projects/lpc21isp/, https://github.com/Senseg/lpc21isp
CAD program is KiCAD. Version 20130518 or newer.

Questions
What parts does the Max232 use?
14 parts, built around the MAX232N. 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.
Where can I download the Max232 KiCad files?
From the BASM/MAX-UART repository on GitHub, at the commit this page was made from: the board is max232.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Max232 design in my own project?
Its repository states no licence, so its author keeps all rights: ask BASM before reusing the design.
