This TTL Serial Cable is used in conjunction with the Redpark Software Develop Kit to create iOS apps that communicate with a serial device. Connects an iPhone, iPad or iPod touch to TTL serial devices like Arduinos, sensor modules, etc. at baud rates up to 57.6 Kbps.
This solution enables the development of iOS app for private use in homes, schools and offices. This cable is not compatible with the Get Console app or with other commercial iOS apps available at the App Store.
Compatible TTL serial devices include Arduino and other micro-controller platforms, scientific instrumentation, data loggers, sensors, and more. When using with a 3.3V logic serial devices such as a Synapse module make sure to use a logic translator or a resistor divider.
This is a 1 meter long cable with a 6 pin connector. The pinout of the 6-pin connector is as follows: RTS, RX, TX, DTR, CTS, GND (orange -> black). This is the standard FTDI pinout with 1 exception, the DTR line is usually the positive supply line. Some very low power devices make use of the DTR signal line to supply power. The Vcc pin is connected to handshaking line DTR. It should supply 8ma but no more. And you may have to turn it ON before power is available at the connector pin. In most cases you will have to have a separate supply for the application board rather than getting Vcc from the TTL serial cable.
