4 This is a tiny, baro-only recording altimeter for
5 model rocketry with integrated telemetry link.
9 We hope with TeleNano to deliver an interesting "introductory" product
10 in a different price category than our flagship products like
11 [TeleMetrum](../TeleMetrum). The combination of a baro altimeter and
12 radio direction finding ability in a super-tiny package seems like it
13 might be fun even for [Estes](http://www.estesrockets.com/) sized rockets!
19 * Recording altimeter for model rocketry
20 * 70cm ham-band transceiver for telemetry downlink
21 * Barometric pressure sensor good to 45k feet MSL
22 * Designed to use a single LiPo rechargeable battery
23 * 1.0 x 0.5 inch board designed to fit inside 18mm airframe coupler tube
25 ### Developer View ###
28 * [TI CC1111F32](http://focus.ti.com/docs/prod/folders/print/cc1111f32.html) Low Power RF System-on-Chip
29 * Sub-1Ghz transceiver
34 * 6 12-bit analog inputs (11 bits with single-ended sensors)
35 * 2 channels of serial I/O
37 * [Freescale MP3H6115A](http://www.freescale.com/webapp/search.partparamdetail.framework?PART_NUMBER=MP3H6115A6U) pressure sensor
39 * Written mostly in C with some 8051 assembler
40 * Runs from on-chip flash, uses on-chip RAM, stores flight data to
41 upper blocks of on-chip flash
43 * [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
44 * [SDCC](http://sdcc.sourceforge.net/) compiler and source debugger
46 * The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)
47 * The software is licensed [GPL version 2](http://www.gnu.org/licenses/old-licenses/gpl-2.0.html)
51 The design files can be found on [git.gag.com](http://git.gag.com) in the
52 project [hw/telenano](http://git.gag.com/?p=hw/telenano;a=summary).
56 Two generations of hardware prototypes were built and worked as desired, but
57 we don't plan to make any more at this time. One problem is that the first
58 version of [TeleMini](../TeleMini/) was basically TeleNano plus dual
59 deployment, and the additional cost of the deployment parts was low enough
60 to make TeleMini a more compelling product. Despite that, sales of TeleMini
61 have been slow. We remain interested in a super-small tracking device, but
62 now think we'd rather figure out how to make [TeleGPS](../TeleGPS/) smaller
63 than return to a as simple a tracking device as TeleNano.
