Introduction Nowadays, most of ICs contain digital interface in order to control increasingly complex ICs easily. Richtek Technology developed a bridge board to control the device with digital interface. The bridge board, Wrenboard, provides I2C and GPIO, which can be utilized as 1-wire/PWM. In addition, we also provide the PC-based software (Richtek Bridgeboard Utilities). Users can control the devices by graphical user interface (GUI). This user manual describes the hardware setting and how to update the firmware on the Wrenboard. For the information about software operation, please refer to “Bridgeboard Control Panel User Manual”. 2. Getting Started Figure 1. The Connection of Wrenboard Figure 1. Summarizes the purpose of Wrenboard. This section describes how to install the required components. 2.1 System requirements Operating system: Windows XP, Windows 7, or Windows 8 / 8.1. 2.2 Software installation Install Richtek Bridgeboard Utilities downloaded from http://www.richtek.com/shareEVB/RTBridgeboardUtilitiesV133.exe 2.3 Hardware installation 1. Connect Wrenboard and target device via connect cable. 2. Insert Wrenboard into a USB port. Copyright © 2015 Richtek Technology Corporation. All rights reserved.

To enable firmware download mode Connect Wrenboard to PC and press FN button. If the red and blue LEDs are blinking alternatively, it means firmware download mode is ready. 7 I2C and GND pins SCL (Serial Clock Line) SCL is a serial clock line with a 2.7kΩ pull-up resistor. It is used to synchronize the data transfers on the I 2C bus. SDA (Serial Data Line) SDA is a serial data line with a 2.7kΩ pull-up resistor. It is used to send data and address. 8 3.3V power pin It is suggested to limit the output current within 100mA. 9 1.8V power pin It is suggested to limit the output current within 100mA. 10 GPIO The GPIO pin can be configured as GPIO (P0.1), 1-wire (GSOW) and PWM function according to programming setting. User can connect this pin to control device in either function. Copyright © 2015 Richtek Technology Corporation. All rights reserved.
