3. Hardware Setup

See Figure 1 for a diagram of the hardware configuration.
1. Attach the desired daughter board to the motherboard at connectors P1 and P2.
2. If using the QFN Socket Daughter Board, place the device to be programmed into the socket.
3. Place shorting blocks on J7 and the +3VD-VDD_PWR jumper pair on J6, as shown in Figure 1.
4. Connect the motherboard's P5 USB connector to a PC running the Silicon Laboratories IDE using the USB
Cable.
5. Connect the ac-to-dc power adapter to connector P3 on the motherboard.
Notes:
1. Use the Reset icon in the IDE to reset the target when connected during a debug session.
2. Remove power from the motherboard and remove the USB cable before removing a daughter board from the
motherboard. Connecting or disconnecting a daughter board when the power adapter or USB cable are connected can
damage the motherboard, the daughter board, or the socketed device.
3. Remove power from the motherboard and remove the USB cable before removing a C8051T62x/32x device from the
socket. Inserting or removing a device from the socket when the power adapter or USB cable are connected can
damage the motherboard, the daughter board, or the socketed device.
4. The above hardware setup instructions configure the development system to be powered through the onboard 3.3 V
regulator. For other power options, see "7.3. Power Supply Headers (J6 and J7)" on page 15.
