# TeleBT
TeleBT provides the equivalent of a [TeleDongle](../TeleDongle), with
-the addition of [Bluetooth](http://www.bluetooth.com) as an alternative to
-USB for connection to the ground station computer.
+both USB and [Bluetooth](http://www.bluetooth.com) for connection to the
+ground station computer or mobile device.
The RF filter components are set for use in the vicinity of 435 Mhz.
-These are photos of prototype version 0.2:
+These are photos of the first production version, 1.0. Maybe someday we'll
+get around to adding photos of the current production version 4.0, but they
+look pretty similar once they're in the blue box!

-## Future Plans ##
+For those who don't have ready access to the gEDA suite, here are pdf snapshots
+of the files for Production PCB version 4.0 in more easily readable form.
-Two prototype versions have been built with different physical form factors.
-We have working firmware, and a prototype of support in AltosUI. Work is
-also underway on an [Android](http://www.android.com) version of AltosUI.

+* [pcb artwork](v4.0/telebt-big.pdf)
+* [bill of materials](v4.0/partslist.csv)
-Prototype version 0.3 is underway, resolving mechanical fit issues in the box
-we've chosen and updating the circuit to use our now-preferred LiPo charger
-chip. We hope this version will be one we're willing to put in to production.
+## [History of TeleBT](history) ##
-No firm schedule for production and sale of TeleBT has been set yet, but we
-hope to have this product for sale by the end of 2012.
