How to connect the TTL-RS232R-cable to a arduino mini 04 ?
(it's a 1x6 pin connector with GND-CTS-VCC-TxD-RxD-RTS)
Seems i can not connect it directly, as the dealer said.
Which connection must be connected (RX,TX,VCC,GND) ?
which are not necessary (CTS,RTS) ?
Should i recombine the signal sequence of the connector to fit the
arduino min ?
