Drynkit: common questions
What microcontroller does the Drynkit use?
The Drynkit is built around the ESP-12E, from the ESP8266 family.
How big is the Drynkit PCB?
The Drynkit measures 40 × 70 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Drynkit?
42 components, from 24 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 Drynkit design files?
From the phlmn/drynkit-pcb repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Drynkit design in my own project?
The repository has no license, so all rights stay with phlmn. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Drynkit 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.
