 * USB: USB mini-B connector. The main connector. The host software communicates (sniffing,...) through USB with the board. It can also be used to flash the micro-controller (using DFU).
15 9 tsaitgaist
 * serial: 2.5 mm jack serial cable, as used by osmocomBB. port used to debug the device (printf goes there).
16 18 zecke2
 * debug (P3): same as serial, but using the FTDI serial cable. '''It is recommended to cut the voltage wire of the 6pin FTDI connector before plugging the cable into the simtrace.'''
17 9 tsaitgaist
 * jtag (P1): JTAG 20 pin connector to do hardware assisted debugging.
18 9 tsaitgaist
 * BT1: battery connector (4.5-6V DC). normally the USB provides power, but the battery port can be used for autonomous use of SIMtrace. The sniffing can be saved in the flash (U1).
19 9 tsaitgaist
 * FFC_SIM (P3): to connect the flat flexible cable with SIM end for the phone.
20 9 tsaitgaist
 * SIM (P4): put your SIM in there (instead of in the phone)
21 9 tsaitgaist
 * reset (SW1): to reset the board (not erasing the firmware). If your are too lazy to unplug and re-plug the USB.
22 9 tsaitgaist
 * bootloader (SW2): used to start the bootloader so to flash the device using DFU. press when plugging in the USB.
23 19 zecke2
 * test (JP1): short circuit using a jumper to flash using [wiki:SIMtrace/Firmware#EnteringtheSAM-BAmode SAM-BA].
24 9 tsaitgaist
 * erase (JP2): short circuit using a jumper to erase completely erase the firmware.

The schematics, Gerber files, etc. can be found in the 'hardware' subdirectory of the simtrace.git repository:

We're using Kicad as EDA tool.  Most of the work on the schematics and Gerber files has been done by Kevin Redon,
33 1 laforge
based on the original design by Harald Welte.

== Interconnections ==
38 15 zecke2

The hardware schematics are very, very simple:
40 15 zecke2
41 15 zecke2
 * Connect SIM-RST with PA7
42 15 zecke2
 * Connect SIM-I/O with PA6(TXD0) and PA1(TIOB0)
43 15 zecke2
 * Connect SIM-CLK with PA2(SCK0) and PA4(TCLK0)
44 15 zecke2
 * Connect SIM-GND with GND
45 15 zecke2
46 15 zecke2
== Mode of operation ==
47 15 zecke2
48 15 zecke2
The USART of the AT91SAM7S is capable of T=0. The documentation only mentions it in clock-master mode, like you
49 15 zecke2
would run it in a smart card reader to actively talk to a smart card. However, by using the USART input clock multiplexer,
50 15 zecke2
you can use an externally-generated CLK like the one from the SIM card socket of the phone.
51 15 zecke2
52 15 zecke2
Unfortunately, the Rx Timeout feature of the USART is not working in T=0 mode, so I had to re-implement Rx timeout (waiting time)
53 15 zecke2
handling by means of the TC (timer/counter) block 0.  Due to technical limitations, we will wait up to one byte (12 etu) more
54 15 zecke2
than we should.

This is identical to v1.0 on the schematics side, we simply altered the footprints of some components to accommodate
65 7 laforge
whatever the SMT factory had in stock.  Specifically the LED are 0805 instead of 0603, and the shottky diodes are
66 7 laforge
in a slightly awkward looking very large package.

Never really was an official release.  However, a friend took the unfinished Gerber files and built 5 units.

100 7 laforge
Since the Gerber was not finished, we had to do lots and lots of re-work in order to make them work at all.
