Questions
How big is the BCI 0802 update PCB?
It measures 47.2 × 23.1 mm and has 2 copper layers, 1.6 mm thick.
What parts does the BCI 0802 update use?
76 parts, built around the MDBT50Q-1MV2, ADS1299-4PAG, TPD4E1B06DCKR-TP and MCP73871-2AAI/ML. 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 BCI 0802 update KiCad files?
From the mandyliao66/BCI_Documents repository on GitHub, at the commit this page was made from: the board is _KiCAD/BCI_0802_update.kicad_pcb and its schematic _KiCAD/BCI_0802_update.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the BCI 0802 update design in my own project?
Its repository states no licence, so its author keeps all rights: ask mandyliao66 before reusing the design.
