Rust Jupyter Kernel and FTDI (Part III)
TM1638 IC appears in “LED&KEY” and “QYF-TM1638” modules, though the wiring of segments and grid pins are different between these two. (reference link for LED&KEY)
Can you figure out the push button connections to TM1638 without a schematic? Or in general, how would you test out a piece of new hardware before committing it to your schematic…
