Description
RS232 to TTL adapter using MAX233 chip. Includes DTR support so that COM1 on PC can be used to program Arduino from IDE. Optional +- 10V output pins. The TTL output pin layout is similar to the popular FTDI USB TTL serial adapter apart from no CTS support. An external 5V source is required to power this circuit.
