App cam roller: common questions
What microcontroller does the App cam roller use?
The App cam roller is built around the ESP-12F, from the ESP8266 family.
How big is the App cam roller PCB?
The App cam roller measures 57 × 37 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the App cam roller?
22 components, from 10 distinct parts. The full bill of materials is listed on this page.
Where can I download the App cam roller design files?
From the zyyan20h/PCBRenewal repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the App cam roller design in my own project?
The repository has no license, so all rights stay with zyyan20h. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the App cam roller 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.
