Overview
Floww is an open-source printed circuit board by FabLab-Merida, from the FabLab-Merida/rFLOW repository on GitHub, published under the GPL-3.0 licence. It is a 2-layer board of 78.7 × 43.2 mm with 11 parts on 30 nets, routed with 202 tracks and 0 vias.
It is built around the ATMEGA328P-PU. Its parts include 6 connectors, 3 resistors, 1 capacitor and 1 IC. It belongs with the AVR (ATmega, ATtiny) boards of this library.
Main components

README.mdrFLOW - FabLab Mérida
Proyecto made in FabLab Mérida por el cual mediante el reciclaje de una antigua plancha de vapor y algunos componentes electronicos, se ha convertido en una estación de soldadura BGA monocapa. Capaz de llegar hasta 250º, ideal para multiples tipos de pasta de estaño.
Motivación
La principal motivación tras este proyecto es buscar una solución económica a la creacion de PCBs y reparación de estas promoviendo la economia circular y el reciclaje de componentes y piezas.
Materiales
1 * Relé de 5V que soporte como miínimo 250V y 13A.
1 * Termistor (vease el .ino para mas información).
1 * Resistencia de la plancha de vapor.
1 * Baquelita monocapa virgen.
1 * ATMEGA 328p.
3 * Botones Push.
3 * Resistencias de 1kO.
1 * Resistencia de 4.7kO.
1 * Condensador de 10uF.
1 * Potenciometro 10kO.
1 * LCD 16*4 segmentos.
Resultados
La posibilidad de usar un amplio rango de temperatura estable ha dado lugar a múltiples aplicaciones extra, desde el anteriormente mencionada creación de PCBs pasando por facilitar soldaduras por aire manteniendo la zona caliente o secado de filamento de impresora 3D.
Observaciones
Se necesita que el Atmega use la frecuencia de relog interna de 8MHz, para ello se necesita grabar el bootloader por uno sin los parametros de Arduino, en la bibliografía encontrará información de como hacerlo.

Questions
How big is the Floww PCB?
It measures 78.7 × 43.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Floww use?
11 parts, built around the ATMEGA328P-PU. 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 Floww KiCad files?
From the FabLab-Merida/rFLOW repository on GitHub, at the commit this page was made from: the board is PCB/floww.kicad_pcb and its schematic PCB/floww.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Floww design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
