Direct Connect

Direct connection is a funky trick we use to connect the output of the GPS serial TTL UART directly

to the usb-serial converter chip on an Arduino. This takes the Arduino out of the picture an can

make it easy if you want to experiment sending commands directly, or using the Windows software

(the Arduino would act like a USB->UART bridge)

Direct Connection Using the Switch (Uno/Mega)

First, load a 'blank' sketch into the Arduino:

This is will free up the converter so you can directly wire and bypass the Arduino chip. Once you've

uploaded this sketch, flip the switch on the shield to Direct

Direct Connection by flipping the switch on this shield only works if you're using an

Uno/Duemilanove/Diecimila/compatible OR a Mega (any type). It will not work with a Leonardo

(the Leonardo does not have a USB/Uart chip) or Due (haven't tested, but assume it doesn't)

// this sketch will allow you to bypass the Atmega chip

// and connect the GPS directly to the USB/Serial

// chip converter.

// Connect VIN to +5V

// Connect GND to Ground

// Connect GPS RX (data into GPS) to Digital 0

// Connect GPS TX (data out from GPS) to Digital 1
