4 This is an RF interface board for use with [Arduino](http://arduino.cc)
5 systems. It provides the equivalent of a [TeleDongle](../TeleDongle)
6 plus [Bluetooth](http://www.bluetooth.com), plus a microSD socket for
9 The RF filter components are set for use in the vicinity of 435 Mhz.
11 These are photos of the first prototype:

25 or as a USB peripheral
26 * 70cm ham-band transceiver compatible with [Altus Metrum](../) products,
27 programmed for 38k4 GFSK data rate with forward error correction
30 * 4 pin Tyco MicroMaTch connector for debug and flash programming
31 * 8 pin Tyco MicroMaTch connector supports serial or SPI interface
32 * micro SD socket for Arduino data storage (not connected to CC1111!)

36 * [TI CC1111F32](http://focus.ti.com/docs/prod/folders/print/cc1111f32.html) Low Power RF System-on-Chip
37 * Sub-1Ghz transceiver
42 * 6 12-bit analog inputs (11 bits with single-ended sensors)
43 * 2 channels of serial I/O
45 * interfaced to Arduino via async serial plus two handshake pins
46 * Rayson BTM-182 (Bluetooth SPP module) using async to CC1111
47 * micro SD card socket interfaced to the Arduino via SPI
48 * 150mA 3.3V LDO regulator
49 * can take input from either USB or the unregulated Arduino input
50 * input and output appear on 8-pin companion connector
52 * Written mostly in C with some 8051 assembler
53 * Runs from on-chip flash, uses on-chip RAM
54 * USB serial emulation for data interface
56 * [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
57 * [SDCC](http://sdcc.sourceforge.net/) compiler and source debugger

64 There is a single manual for all Altus Metrum products,
65 which is available in [html](../AltOS/doc/altusmetrum.html) and
66 [pdf](../AltOS/doc/altusmetrum.pdf) formats.
68 The hardware design current gEDA files are available from
69 [git.gag.com](http://git.gag.com) in the project
70 [hw/teleshield](http://git.gag.com/?p=hw/teleshield;a=summary).
74 The prototype v0.1 boards work fine. Feedback from showing them at the
75 Arduino mini-conference at LCA 2012 resulted in elimination of the Bluetooth
76 interface. Updated boards have not been built yet, but
77 [schematic and artwork files](v0.2/) are available for review and comment.
79 No significant interest in this design ever materialized, so we have no plans
80 to make any more at this time.
