Primer diseño de la principal en KiCad: STM32G431RBT6 y ESP32-S3-WROOM-1U-N8R8 con antena externa U.FL, alimentación integrada, reset, depuración y UART. Incluye IRM-30-24 aislado, buck de 24 V a 12 V, buck de 3,3 V, corte del frontal y acondicionamiento de NTC, caudalímetro, nivel de agua, tres contactos y un DRV8876 para el motor del grupo y una etapa low-side para la válvula, alimentados desde una entrada aislada de 24 V con ramas protegidas por separado. Un TPS3828 externo supervisa el STM32; la lógica AND bloquea los actuadores y un segundo interlock gobierna el relé general de fase. 159…

Controller core reva: common questions
What microcontroller does the Controller core reva use?
The Controller core reva is built around the ESP32-S3-WROOM-1U-N8R8, from the ESP32 family.
How big is the Controller core reva PCB?
The Controller core reva measures 141.6 × 135.2 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Controller core reva?
187 components, from 158 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Controller core reva design files?
From the itorralbo/open-saeco-controller repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.
Can I use the Controller core reva design in my own project?
Yes, under the terms of its MIT license, which itorralbo chose for the repository.
Can I test firmware for the Controller core reva without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
