Wifi epaper: common questions
What microcontroller does the Wifi epaper use?
The Wifi epaper is built around the STM32L433CCT6, from the STM32 family.
How big is the Wifi epaper PCB?
The Wifi epaper measures 99.1 × 99.1 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wifi epaper?
71 components, from 61 distinct parts. The full bill of materials is listed on this page.
Where can I download the Wifi epaper design files?
From the FrankBuss/wifi-epaper repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Wifi epaper design in my own project?
The repository has no license, so all rights stay with FrankBuss. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wifi epaper without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
