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 If there is sufficient interest, we will produce some. Exactly if or
80 when that will happen and what they might cost are not known yet.
