Virtual clues: common questions
What microcontroller does the Virtual clues use?
The Virtual clues is built around the WeMos_D1_mini, from the ESP8266 family.
How big is the Virtual clues PCB?
The Virtual clues measures 53.5 × 67.5 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Virtual clues?
28 components, from 20 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 Virtual clues design files?
From the r0oland/laserhannes_kicad_electronics repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Virtual clues design in my own project?
Yes, under the terms of its Apache-2.0 license, which r0oland chose for the repository.
Can I test firmware for the Virtual clues 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.
