UnlockOslo: common questions
What microcontroller does the UnlockOslo use?
The UnlockOslo is built around the ESP-12E, from the ESP8266 family.
How big is the UnlockOslo PCB?
The UnlockOslo measures 65 × 56 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the UnlockOslo?
89 components, from 34 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 UnlockOslo design files?
From the jonnor/UnlockOslo repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the UnlockOslo design in my own project?
Yes, under the terms of its MIT license, which jonnor chose for the repository.
Can I test firmware for the UnlockOslo 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.
