General Description of Hardware

The DS18B20 EV system demonstrates the DS18B20,

high-precision digital thermometer and thermostat. The

USB2PMB2 module and the EV system complete the

system. The DS2482 acts as the 1-Wire master for the

the connector J1 is a Pmod-compatible connector. If the

master does not have a Pmod-compatible connector, then

make connection directly to the SCL, SDA, AD0, and AD1

test points. Make sure the return ground is the same as

the DS2482. Please refer to Table 1 for jumper position.

User-Supplied 1-Wire

To evaluate the EV system with a user-supplied 1-wire

bus, the connector J1 is a Pmod-compatible connector. If

the master does not have a Pmod-compatible connector,

then make connection directly to the DQ test points. Make

sure the return ground is the same as the DS18B20.

Please refer to Table 1 for jumper position.

The DS18B20 and DS2482 are powered through USB

by default when a Pmod -compatible master module is

connected to the J1 connector of the EV system. If a

allowed on the J1 connector. In this case, apply a voltage
