Questions
How big is the Sendit PCB?
It measures 160.7 × 51.7 mm and has 4 copper layers, 1.57 mm thick.
What parts does the Sendit use?
228 parts, built around the ESP32-S3-WROOM-1-N16R8, SN74LV1T34DBV, ADS1115IDGSR and AP63205WU. 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 Sendit KiCad files?
From the hoeken/sendit repository on GitHub, at the commit this page was made from: the board is sendit/sendit.kicad_pcb and its schematic sendit/1115_adc.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Sendit design in my own project?
Its repository publishes it under the GPL-3.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
