1. General Information and Introduction
1.1 Introduction
The Sensor Evaluation Kit is designed to test the functional operation of various sensor types. It includes one Base Board
and several Breakout Boards. The Base Board is a controller board with a LAPIS MCU. The Breakout boards are sensor
boards containing different types of sensor ICs.
This guide will help you understand how to connect Breakout Boards to the Base Board. It will also show how the Base
Board obtains data from sensors, and converts and displays the results on a computer screen.
1.2 Quick Start Guide
Step 1: Check to make sure the latest drivers are installed on your computer for communicating with the Base Board
(LAPIS MCU) via USB. If not, please go to http://www.ftdichip.com/Support/Documents/InstallGuides.htm to access the
driver files.
Step 2: Verify that the jumper settings are set as follows:
• Power Selection Switch (J1) is in the VBUS position (position 3).
• Reset Selection Header (J2) is in the USR_RST position (connect pins 1 and 2).
Step 3: Plug the Sensor Breakout Board into the Base Board.
Step 4: Connect the Base Board + Breakout Board to the computer via USB cable.
Step 5: Run the Serial Terminal tool (PuTTy), configure PuTTy to run in Serial mode with a data rate of 9600bps .The output
data will be displayed on the terminal screen. If no output is displayed, please go to Appendix A: Programming the Base
Board Instructions to program/re-program the Base Board.

2. Base Board Overview
2.1. Hardware
The block diagram of the Base Board is shown in Figure 5. LAPIS Semiconductor's ML610Q112 MCU is used to interface
with the Breakout Board via Sensor Interface Headers and with the PC via the UART-to-USB IC FT230XS-R.

Designator Position Description
J1 1 (EXT_PWR) External Power Source selected
2 (OPEN) No Power Source selected
3 (VBUS) VBUS Source selected
J2 2-1 (USR_RST) User Reset selected
2-3 (nE_RST) nanoEASE Reset selected
Table 2: Base Board - Jumper/Switch Configurations
The ML610Q112 is a high-performance 8bit CMOS microcontroller that incorporates a variety of peripheral circuits, such as
timers, PWM/UART/I2C bus interface (master/slave), synchronous serial port, voltage level supervisor, analog comparators,
and 10-bit successive approximation type A/D converter, around an 8bit nX-U8/100 CPU. The nX-U8/100 is capable of
efficient instruction execution at 1 instruction per clock cycle via parallel processing and pipeline architecture. The Flash
ROM installed as program memory and on-chip debugging function enable program debugging and programming on the
customer’s board.
The Base Board is powered by the VBUS pin in the USB connector or an external power source connected via Header J3.
Switch J1 is used to select the power source.

The debugging function of ML610Q112 is extremely useful. You will be able to single-step through your code to quickly
find problems and solutions as well as set breakpoints and create and save watch lists of variables to help you better
understand what is going on inside your code. To manually reset the micro using Button S1, move J2 to the USR_RST
position.

2.2. Software
The source code of the Base Board software can be downloaded from
https://github.com/ROHMUSDC/ROHMSensorPlatformEVK
The flow diagram of the Base Board software is shown in Figure 13. The “Sensor Control” value is the input data from the
PD port of ML610Q112. This value is used to detect the type of Breakout Board connected to the Base Board (refer to
Table 1).

3. Breakout Board Overview
3.1. Hall Sensor Breakout Board
3.1.1. BU52011HFV Breakout Board
The BU52011HFV Breakout Board provides a simple environment to quickly evaluate the performance of the BU52011HFV
sensor. The BU52011HFV features magnetic switches that can operate both the S- and N-poles, upon which the output
goes from High to Low.
Figure 14: BU52011HFV Breakout Board (Top and Bottom Views)
Figure 15: BU52011HFV Breakout Board Block Diagram
The block diagram and schematic of the BU52011HFV Breakout Board are shown in Figures 15 and 16, respectively.
Resistors R161 to R166 are used to set the Sensor Control value for the board. Pin 5 (OUT1) of the BU52011HFV is
connected to the Base Board via Pin 1 (GPIO0) of Sensor Interface Header 1.
