An ESP32-S3 game tool. The keypad columns relied on internal pull-ups, and "the firmware no longer uses internal pull-ups, so external ones are added." gen_sch.py adds R17 to R20, the hardware README gets new pin and material tables, and the cost goes up 4 MXN. Still pending is "regenerate airsoft_tool.kicad_sch, option B, the PDFs and the materials Excel on a machine with KiCad. It couldn't be done here and the graphical result was not reviewed." Translated from Spanish.
