Questions
How big is the TT 0.4 Control board! PCB?
It measures 224 × 90.4 mm and has 2 copper layers, 1.6 mm thick.
What parts does the TT 0.4 Control board! use?
68 parts, built around the MS5837-30BA, LM1117T-3.3 and B4B-XH-A(LF)(SN). 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 TT 0.4 Control board! KiCad files?
From the sreedharRP/TT_0.4_Control_Unit_PCB_design repository on GitHub, at the commit this page was made from: the board is TT_0.4_Control_board!/TT_0.4_Control_board!.kicad_pcb and its schematic TT_0.4_Control_board!/TT_0.4_Control_board!.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the TT 0.4 Control board! design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
