While using a [TeleDongle](../TeleDongle/) board as a USB to RF interface to
### User View ###
-* Hand-held unit about the size of a calculator with 4 line 20 character LCD
-* Antenna for the telemetry stream from [TeleMetrum](../TeleMetrum/)
-* Integrated GPS receiver core to allow display of current user position,
-and relative position of GPS-equipped rockets
+* Hand-held unit about the size of a calculator
+* 4 line by 20 character text LCD
+* "joyswitch" for user input (up, down, left, right, push)
+* Antenna connector for the telemetry stream from [TeleMetrum](../TeleMetrum/)
+* Integrated GPS receiver and antenna to allow display of current user
+ position, and relative position of GPS-equipped rockets
+* Audio amplifier and speaker for voice status updates
* Integrated rechargable battery
-* USB interface for configuration and power
+* USB interface for configuration, power, and flight log extraction
### Developer View ###
* equivalent of a [TeleMetrum](../TeleMetrum/) less the sensors
* [Atmel ATtiny48](http://www.atmel.com/dyn/products/product_card_v2.asp?PN=ATtiny48) used as an I/O expander
* 4 line, 20 character transreflective text LCD display
- * "joystick" switch for user inputs
-* LiPo battery
+ * multi-directional switch for user inputs
+* 2Ah LiPo battery for all-day use
* Software Features (planned)
* [AltOS](../AltOS) for the cc1111 and simple C for the AVR
* Tools Used

+As of 23 October 2010, v0.1 circuit boards and a matching paste mask are
+out for fab. With any luck, we hope to have a couple prototypes working by
+the end of calendar 2010.
