2. INTRODUCTION
The Nokia 12 test board is a development tool that application developers and system integrators can use for developing application hardware and software for Nokia 12 module. It manages direct current (DC) voltages, SIM card, I/O’s, and audios. It makes it possible to measure several interfaces by pin headers, and handle the software interfaces of the D9 connectors.
The Nokia 12 module has been type approved with the Nokia 12 test board.

3. TECHNICAL DESCRIPTION
The Nokia 12 test board includes the following features and functionalities:
• Required powering for the Nokia 12 module using the Nokia ACW-6 AC power supply.
• Reset button
• SIM reader with a ‘lid open’ indication switch.
• RS-232 level translators for all three serial ports of the Nokia 12 module.
• Analog audio connector for the Nokia HSU-3 handset.
• Switch for standard AT commands.
• Pin headers for I/O access.
The main components of the Nokia 12 test board are illustrated in Figure 1.

3.1 POWERING Powering is carried out with the National Semiconductors LM2676S DC-DC converter, output voltage is adjusted to 3.8V. Input voltage can be between 8 -40V.
IO voltage is conveyed via a linear regulator, and the voltage is adjusted to 3.3V.
A 3A step down converter is used to produce module VCC. Low ESR (Equivalent Series Resistance) capacitors are used.

3.2 SIM CARD READER The SIM card reader of the Nokia 12 test board is directly connected to the M2M System Connector. The VSIM (pin47) decoupling capacitor must be present in all designs. The connections between the SIM card reader and the M2M System Connector are illustrated in Figure 3.

The SIM card reader has a switch that indicates when lid is open. The ‘lid open’ switch is connected to the Nokia 12 module SIM_DET line.
3.3 RS-232 CONVERTERS All three serial ports of the Nokia 12 module are equipped with RS-232 level converters, and there are three external D9 connectors on the test board, one for each serial port of the Nokia 12 module.
RS-232 converter switches for PORT1 and PORT2/PORT3 The RS-232 level converter switches are illustrated in Figure 4.
6/26
Figure 4. The RS-232 level converter switches on the Nokia 12 test board When the RS-232 translators are ON, PORT1 and PORT2/PORT3 are connected the Nokia 12 module via the M2M System Connector.
When the RS-232 translators are OFF, PORT1 and PORT2/PORT3 are not connected the Nokia 12 module via the M2M System Connector. When the RS-232 translators are off, it is possible to access the Nokia 12 module by using the pin headers (1-4).
Note: The voltage level at the pin headers is at normal logic level (3.3V/0V), not at RS232 levels.
3.4 AUDIO
For testing analog audio, the Nokia 12 test board includes a connector for the Nokia HSU-3 handset. Microphone signals from MOD6 connector (for HSU-3) are amplified in the Nokia 12 test board because the Nokia 12 module requires higher level signals for MIC inputs. The Nokia 12 test board microphone amplifier is illustrated in Figure 5.
7/26
Figure 5. Nokia 12 test board microphone amplifier
Note: The HSU-3 handset can be purchased from Nokia dealers.
Earphone lines go straight through DC capacitors from the Nokia 12 to the MOD6 connector. The acoustic frequency response is not according to GSM specification; electrically it is flat.
Microphone input selection switches The microphone input selection switches are illustrated in Figure 6.
8/26
Figure 6. Microphone input selection switches
MIC FROM HSU-3 means that microphone signals are routed from the Nokia 12 test board HSU- 3 connector to the Nokia 12 module. MIC FROM PIN HEADER means that microphone signals are routed to pins 10 and 11 in pin header X100 on Nokia 12 test board edge.
3.5 COMMUNICATION MODE The communication mode switches are illustrated in Figure 7.
9/26
Figure 7. Communication mode switches
When the switches are in the normal mode position, the BSI line of the Nokia 12 module is floating. When the switches are in the AT mode position, a 68 kohm resistor is connected between the Nokia 12 module BSI line and ground.
Note: To use the normal mode/AT mode settings on the test board, the connection type setting on the Nokia 12 Configurator must be set to ‘HW Detection’. If the connection type setting on the Nokia 12 Configurator is set to ‘AT’, the communication mode switch settings on the Nokia 12 test board are overridden.
3.6 LED INDICATORS There are LEDs on the Nokia 12 test board that indicate the states of all Nokia 12 module I/O pins (LED on means ‘1’, and LED off means ‘0’).
3.7 PIN HEADERS The pin headers located on the side of the Nokia 12 test board can be used to connect any of the I/O pins directly to an external application. The Nokia 12 test board I/O pin headers and their functions are illustrated in Figure 8.
10/26
Figure 8. I/O pin headers and their functions
Note: If any PORT1 pins are used as I/O switches, S404 must be set so that N403 level translator is in the Hi-Z state. If any of PORT2 or PORT3 pins are used as I/O switches, S403 must be so that N402 level translator is in the Hi-Z state.
3.8 M2M SYSTEM CONNECTOR PINOUT The odd number pins (1, 3, 5, 7…) are on one the top row of the connector and the even number pins (2, 4, 6, 8…) on the bottom row as illustrated in Figure 9.

When the Nokia 12 module is transmitting data, there is a current peak (max. 2A ) at 4.6 ms intervals that lasts 0.577ms (1 TX slot) or 1.154 ms (2 TX slots). Average power consumption is about 500 mA. The power supply should be designed
