A/B-3/4: The Murata ZPA2326 (IC2) runs at a voltage of +1V8-GND while the ATtiny85 (U7) runs at a voltage of +3V3-GND and for this reason, the I2C
signals would be at different logic levels. In order to convert the logic levels from one to another, a bidirectional bi-channel logic level converter is used.

C/D-1/2/3: The Capacitive MEMS Digital Barometric Absolute Pressure Sensor, Murata ZPA2326.</text>
<text x="7.62" y="144.78" size="2.54" layer="97" font="vector" align="top-left">Microcontroller:

A/B-1/2/3: The microcontroller has 5 general purpose I/O pins, of which a few are multiplexed with the hardware TWI/SPI. These pins have different
functions while programming and while executing the flashed firmware, and for this reason, solder joints are required to connect multi-purpose pins.

A/B-3/4: Test points for the microcontroller.

A/B-5/6: The microcontroller, Atmel ATtiny85.

C/D-1/2: Pin headers for programming the microcontroller using an external device.</text>
<text x="7.62" y="104.14" size="2.54" layer="97" font="vector" align="top-left">Data Output Interface:

A-1/2: Test points for the data output interfaces.

A-5/6: The 4-20 mA current-loop transceiver, Burr-Brown XTR117. This transceiver converts the current through its input pin into an amplified current
through the output pin. The voltage output of the 8574 (U3) is converted into a current input to the XTR117 (U4) using a 25k ohm resistor.

B/C-1/2: The TTL-to-RS232 converter, Texas Instruments MAX3221 (U6). This behaves as the RS232 transceiver of the microcontroller.

B/C-3/4: The TTL-to-RS485 converter, Linear Technology LTC2850 (U1). This behaves as the RS485 transceiver of the microcontroller.

B-5/6: In order to generate an analog voltage between 0 and +5.0 V, the 8574 (U3) requires I2C signals between +5V0-GND. In order to convert the logic
levels from one to another, a bidirectional bi-channel logic level converter is used.

D-1/2: The sensor can offer digital and analog outputs simultaneously. However, either one of RS232 or RS485 can be used at a time and either one of
0-5 V or 4-20 mA can be used at a time. In order to choose between these, two sets of jumpers are used - the formats configurable on-the-go.

D-3/4: The connector for data exchange with the external world.

C-5/6: The sensor can offer measurements as an analog voltage in the range of 0 and +5.0 V and as
an analog current in the range of 4 to 20 mA. In order to generate a voltage output from the pressure
measurements, the Texas Instruments DAC8574 (U5), a quad-channel DAC, is used.

*Revision D and beyond feature Texas Instruments DAC8574 instead of the Microchip DAC MCP4725.</text>

A/B-4/5/6: The sensor is expected to operate over a wide input voltage range, between +7V0-GND and +30V0-GND. For this reason, a wide-range input
buck converter, delivering +5V0 at upto 1 A is used.

C/D-1/2/3: The +5V0 rail is subsequently down-converted to +3V3 in order to power the microcontroller and the digital output transceivers.

A/B-1/2/3: The +3V3 rail is subsequently down-converted to +1V8 in order to power the sensor's chip.
