Powering the unit will require a decent power supply. The kits we supply will come with either an Apple 12W supply or an Anker. If you use the included ON/OFF switch you can't use the included USB C to USB C cable. You must use a USB A to C because the switch doesn't have a signal wire for proper charge rate. A USB C to USB C cable can be connected directly to the Pi.
The included antenna is a BU-353S4. It can be plugged into any of the Pi USB ports. After launching the software there is a menu for connecting the antenna. You will typically need to select the "Prolific" device the first time you use the software. This has already been done if this you have purchased an assembled device. If you end up plugging in other USB devices you may need to select the antenna again because the device paths could have possibly been changed.
Why "Prolific"? This is the USB to Serial driver used by the GPS antenna.
Where is the keyboard?
If you are using 1.0. (1.1 coming out Jan. 1) you will need to use the system matchbox on screen keyboard. You go to the Pi icon --> Accessories --> Keyboard. You can use this to connect to Wifi, enter implement width, etc.
1.1 will have a screen in the app for the field name and width. You will still need the matchbox keyboard for WIFI connection.
Launching the software
On the Pi desktop are two executables. The icons launch with a double tap. There is one for the software and another for an update script. A major version release is slated for Jan. 1, 2021 so you can run the update script to get that. The update script compiles and builds the program. This can take around an hour so if you see the terminal screen up for a while do not panic.
