A small, simple keyboard one one PCB using tactile switches and an ESP32

The STMPE1600Q is an interface I, O Expander made by STMicroelectronics in a QFN-24-EP(4x4) package with 25 pins. -40℃~+85℃ 1.65V~3.6V 16 400kHz I2C Interrupt Output Reset function、Cascade and address expansion QFN-24-EP(4x4) I/O Expanders ROHS.
PCBKit's library has its KiCad symbol (EasyEDA_Cloud:STMPE1600QTR, from EasyEDA) and its footprint (Package_DFN_QFN:QFN-24-1EP_4x4mm_P0.5mm_EP2.6x2.6mm, from KiCad's library), ready for a KiCad board. JLCPCB lists it (part C116979). 1 open-source board in 1 repository on GitHub use it.
