3 This is an expansion board for [TeleMetrum](../TeleMetrum/) intended to
4 support science projects. It provides 12 analog inputs with selectable
5 thermistor support, and 5 general purpose I/O pins. This board can also
6 be used standalone as a USB I/O device.
10 Bdale's son Robert is interested in mapping the temperatures experienced
11 by nose cones and fins in flights beyond Mach 1, and we're working with
12 our good friend Jeff Lane from
13 [Shockwave Rocketry](http://www.shockwaverocketry.com/)
14 to instrument one or more of his nose cones in pursuit of that goal. And
15 it's easy for us to imagine other experiments that would be facilitated by
16 having generic analog data inputs and a few control lines.
22 * Small circuit board mounted near [TeleMetrum](../TeleMetrum/)
23 * Requires [TeleMetrum](../TeleMetrum/) v0.2 or later, as v0.1 does not
24 have the required companion board interface
25 * 12 analog input channels, each of which can independently be configured
26 for an NTC thermistor or generic 0-3.3 volt analog input.
27 * 5 general purpose I/O lines
28 * On-board flash memory for data logging.
29 * USB interface for programming and development
31 ### Developer View ###
34 * [Atmel ATmega32U4](http://www.atmel.com/dyn/products/product_card.asp?category_id=163&family_id=607&subfamily_id=760&part_id=4317) Microcontroller
36 * 2.5k + 832 bytes SRAM
38 * 12-channel 10-bit ADC
39 * SPI target interface
40 * USB interface which can be used for programming
41 * In-system programming interface
42 * [Winbond W25Q16](http://www.winbond.com/NR/exeres/A3D21C82-A0B6-4586-A770-2F0883A805FF.htm) serial flash memory
45 * Software Features (planned)
46 * programmed in C using gcc-avr
47 * Runs from on-chip flash, uses on-chip RAM
49 * [gEDA](http://www.gpleda.org/) for schematic capture and PCB layout
51 * The hardware is licensed under the [TAPR](http://www.tapr.org) [Open Hardware License](http://www.tapr.org/ohl.html)

56 A schematic and PC board design exist on [git.gag.com](http://git.gag.com)
58 [hw/telescience](http://git.gag.com/?p=hw/telescience;a=summary),
59 but no prototypes have been built yet.
63 We currently plan to build prototypes of TeleScience in Spring 2011.
