Questions
How big is the 1602 uart driver PCB?
It measures 13.7 × 41.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the 1602 uart driver use?
20 parts, built around the STM8S003F3U6 and AO3401A. 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 1602 uart driver KiCad files?
From the Sasha7b9Work/HandHeld repository on GitHub, at the commit this page was made from: the board is samples/hd44780/1602_uart_driver/1602_uart_driver.kicad_pcb and its schematic samples/hd44780/1602_uart_driver/1602_uart_driver.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the 1602 uart driver 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).
