D-curs-D/8051_Serial_Comm
8051 based serial communication. The PCB Design was done on KiCAD, the simulations were done using proteus and code on keil studios.
Boards in 4 GitHub repositories, designed in KiCad, that use the AT89S52-24PU by Microchip Technology (-40℃~+85℃ 24MHz 256Byte 32 4V~5.5V 51 Family 8 Bit 8KB Built-in FLASH DIP-40 Microcontrollers (MCU/MPU/SOC) ROHS). See how each wires it, with its parts, size, README and files; the AT89S52-24PU’s symbol, footprint and pinout are on its own page.
