Single side SMD PCB for MAX232 - 29x36mm for manual soldering
connect microcontroller(TTL) to PC via COM port (RS-232)

Single side 29x36mm SMD PCB for MAX232 used to connect microcontroller(TTL) to PC via COM port (RS-232).
PCB is designed for manual soldering and this is why SMD chip pads are so long and there is so large space between elements. Manual soldering elements is easy to be done from inside to outside. This means first must be soldered chip, then capacitors and finally connections to the board
