Curio: common questions
What microcontroller does the Curio use?
The Curio is built around the ESP-12E, from the ESP8266 family.
How big is the Curio PCB?
The Curio measures 52.8 × 19.3 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the Curio?
20 components, from 15 distinct parts. The full bill of materials is listed on this page.
Where can I download the Curio design files?
From the phybros/curio repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Curio design in my own project?
Yes, under the terms of its CC-BY-SA-4.0 license, which phybros chose for the repository.
Can I test firmware for the Curio 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.
