README
hardware/sanchez-rev1/README.mdLa arquitectura "Sánchez rev1" se basa en las ideas de otras arquitecturas hardware para FreeDS, separando el diseño en dos PCBs que caben en las cajas estancas usadas por otras arquitecturas hardware.
La arquitectura Sánchez rev1 incluye:
- Conectores para RS485
- Conectores para sensores de temperatura
- Espacio para un sensor montado en la parte inferior de la placa de control, pensado para que doblando las patillas pueda tocar el disipador del TRIAC
- Conectores para relés
- Conector para ventilador controlado por relé 4
- Conectores para pinza amperimétrica
- Conector de dos pines
- Conector de jack de audio de 3.5mm
La novedad con respecto a otras arquitecturas es la circuitería y conectores para poder controlar un ventilador por PWM: la idea es que cuanto mayor sea el porcentaje de PWM, más trabajará el ventilador.
El diseño está hecho con KiCAD, y se incluyen los ficheros Gerber (ya compilados y por separado para cada una de las dos PCBs) para comodidad a la hora de pedir la fabricación de las placas.

Questions
How big is the Freeds sanchez PCB?
It measures 121 × 68 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Freeds sanchez use?
42 parts, built around the ESP32-WROOM-32U, BTA26-600BW, HLK-PM01 and DS18B20. 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 Freeds sanchez KiCad files?
From the pablozg/freeds repository on GitHub, at the commit this page was made from: the board is hardware/sanchez-rev1/freeds-sanchez.kicad_pcb and its schematic hardware/Clinxer - Version ACS712/FreeDS/FreeDS.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Freeds sanchez design in my own project?
Its repository states no licence, so its author keeps all rights: ask pablozg before reusing the design.
