README
BLDC_D28_Drv/README.mdBLDC_D28_Drv
Tiny driver stage for mounting on BLDC motors with 28/29mm diameters.
Highlights:
- Specialized outline for mounting on BLDC motors with 28/29mm diameters. Can also be uesd as a general-purpose 3-phase bridge.
- Features 3 bootstrap half-bridge driver with common footprint. TTL/CMOS logic input compatible.
- Separated power supply for gate driver and motor power makes it capable to drive motors require high volatge.
Status:
Partially verified.

Questions
How big is the EPap PCB?
It measures 37.3 × 29.2 mm and has 2 copper layers, 1.6 mm thick.
What parts does the EPap use?
29 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the EPap KiCad files?
From the SdtElectronics/Biscuits repository on GitHub, at the commit this page was made from: the board is 24pEink/ePap.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the EPap design in my own project?
Its repository states no licence, so its author keeps all rights: ask SdtElectronics before reusing the design.
