CerraduraESP RFID V1.0: common questions
What microcontroller does the CerraduraESP RFID V1.0 use?
The CerraduraESP RFID V1.0 is built around the WeMos_mini, from the ESP8266 family.
How big is the CerraduraESP RFID V1.0 PCB?
The CerraduraESP RFID V1.0 measures 66 × 61 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the CerraduraESP RFID V1.0?
18 components, from 17 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 CerraduraESP RFID V1.0 design files?
From the SmartOpenLab/Proyectos repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the CerraduraESP RFID V1.0 design in my own project?
Yes, under the terms of its GPL-3.0 license, which SmartOpenLab chose for the repository.
Can I test firmware for the CerraduraESP RFID V1.0 without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
