2. Sensor Panel System
Figure 2 shows the Sensor Panel System Block diagram. Typically the Sensor Panel board has five sections: Renesas
Synergy™ S124 microcontroller (MCU), Bluetooth®, user input/output, Sensors, and regulated power supply with
battery. Renesas Synergy™ S124 device is populated along with RL78/G1D BLE module (RY7011). Thus the
acquisition of data from sensors are processed by S124 device and then transmitted through the Bluetooth®module
RY7011. To connect with external device like thermostat, it has two digital inputs and two open drain outputs for
controlling the device. In addition, there is one 12-pin PMOD™connector so that you can utilize on adding more
sensor like Accelerometer or LCD display. You can also monitors the environment parameter using board sensors like
temperature, light, PIR, reed switch and Hall Effect switch. The Sensor Panel board is suitable to evaluate and develop
various sensor applications with S124 device. Using slide switch (S5), the Sensor Panel board can be powered up with
Li-ion battery or external power source.

2.1 Renesas Synergy™ S124 device
This Sensor Panel board uses JTAG programming/debugging interface for S124 device. The JTAG signals can be used
through JTAG connector (J1). Use the SEGGER J-Link for programming to the board and debugging for development.
See detail in schematics sheet 2 of 6.
Table 2 JTAG
To enable JTAG debug with S124 target on the Sensor Panel board, use with jumper JP1 for boot mode as below.
Insert shunt jumper at JP1 SCI boot mode (serial programming mode).
Remove shunt jumper at JP1 Normal boot mode.
2.2 RL78/G1D module (RY7011)
This RY7011 is a Bluetooth Low Energy module incorporated with the RL78/G1D device, 32-MHz crystal resonator
for the RF section, and PCB antenna. This module has been certified on Japan’s Radio Law, FCC certification, IC
regulation, CE mark requirements, and the Bluetooth v4.1 specification. Thus it is suitable to use on Sensor Panel board
yet low power consumption as below:
RF transmission: 4.3 mA (TYP.)
RF reception: 3.5 mA (TYP.)
RF sleep (POWER_DOWN mode): 0.3 μA (TYP.)
