Power Supply The module power supply 3v coin cell batteries or DC 3.3v Power supply pin connection capacitor to chip and pin as far as possible close Capacitor decouples power to the chip Capacitor prevents noise coupling back to power plane. Figure 2： Power Supply PCB Design 6.2. PIO 10 PIOs are provided (4 are multiplexed with SPI debug interface). They are powered from VDD_PIO. PIO lines are software-configurable as weak pull-up, weak pull-down, strong pull-up or strong pull-down. Note: At reset all PIO lines are inputs with weak pull-downs. Any of the PIO lines can be configured as interrupt request lines or as wake-up lines from sleep modes. 6.3. AIO 3 AIOs are provided. They can be connected to internal 10 bits ADC. Their functions depend on software. They can be used to read or output a voltage between 0V to 1.3V. Each of them can be used as a digital output with special firmware. 6.4. PWM 4 PIOs (PIO3, PIO4, PIO9, and PIO10) can be driven by internal PWM module. The PWM module also works while the module is sleep. So it can be used as a LED flasher. These functions are controlled by special firmware. Shanghai Ehong Technologies Co., Ltd Bluetooth Low Energy Module 6.5. UART This is a standard UART interface for communicating with other serial devices. The UART interface provides a simple mechanism for communicating with other serial devices using the RS232 protocol. Table 8: Possible UART Settings Parameter Baud Rate Possible Values Minimum Maximum Flow Control Parity Number of Stop Bits Bits per Byte 1200 baud (≤2%Error) 9600 baud (≤1%Error) 2M baud (≤1%Error) RTS/CTS or None None, Odd or Even 1 or 2 Figure 3： Connection To Host device 6.6. I2C Master The module can act as an I2C master when configured by software. Any two PIOs can be configured as I2C_SCL and I2C_SDA. 6.7. SPI Master The module can act as an SPI master (mode 0) when configured by software. Any four PIOs can be configured as SPI_CLK, SPI_CS#, SPI_DIN and SPI_DOUT. The clock rate of the software SPI is around 470kHz. Shanghai Ehong Technologies Co., Ltd Bluetooth Low Energy Module 6.8. SPI Debug The SPI Debug interface is chosen when SPI_PIO_S is high. The interface is used to program and debug the module. So always place test points or header on PCB for this interface and SPI_PIO_SEL. 7. Reference Design Figure 4： Reference Design 8. Layout and Soldering Considerations 8.1. Soldering Recommendations EH-MC10 is compatible with industrial standard reflow profile for Pb-free solders. The reflow profile used is dependent on the thermal mass of the entire populated PCB, heat transfer efficiency of the oven and particular type of solder paste used. Consult the datasheet of particular solder paste for profile configurations. Comply will give following recommendations for soldering the module to ensure reliable solder joint and operation of the module after soldering. Since the profile used is Shanghai Ehong Technologies Co., Ltd Bluetooth Low Energy Module process and layout dependent, the optimum profile should be studied case by case. Thus following recommendation should be taken as a starting point guide. Refer to technical documentations of particular solder paste for profile configurations Avoid using more than one flow. Reliability of the solder joint and self-alignment of the component are dependent on the solder volume. Minimum of 150um stencil thickness is recommended. Aperture size of the stencil should be 1:1 with the pad size. A low residue, “no clean” solder paste should be used due to low mounted height of the component. 8.2. Layout Guidelines For optimal performance of the antenna place the module at the corner of the PCB as shown in the figure 3. Do not place any metal (traces, components, battery etc.) within the clearance area of the antenna. Connect all the GND pins directly to a solid GND plane. Place the GND vias as close to the GND pins as possible. Use good layout practices to avoid any excessive noise coupling to signal lines or supply voltage lines. Avoid placing plastic or any other dielectric material closer than 6 mm from the antenna. Any dielectric closer than 6 mm from the antenna will detune the antenna to lower frequencies.

Mechanical and PCB Footprint Characteristics Figure 6 ：Physical Dimensions and Recommended Footprint (Unit: mm, Deviation:0.02mm) Shanghai Ehong Technologies Co., Ltd Bluetooth Low Energy Module 10. Reflow Profile The soldering profile depends on various parameters necessitating a set up for each application. The data here is given only for guidance on solder reflow. ℃ 250 217 210 25 min Figure 7: Recommended Reflow Profile Pre-heat zone (A) — This zone raises the temperature at a controlled rate, typically 0.5 – 2 °C/s. The purpose of this zone is to preheat the PCB board and components to 120 ~ 150 °C. This stage is required to distribute the heat uniformly to the PCB board and completely remove solvent to reduce the heat shock to components. Equilibrium Zone 1 (B) — In this stage the flux becomes soft and uniformly encapsulates solder particles and spread over PCB board, preventing them from being re-oxidized. Also with elevation of temperature and liquefaction of flux, each activator and rosin get activated and start eliminating oxide film formed on the surface of each solder particle and PCB board. The temperature is recommended to be 150° to 210° for 60 to 120 second for this zone. Equilibrium Zone 2 (c) (optional) — In order to resolve the upright component issue, it is recommended to keep the temperature in 210 – 217 ° for about 20 to 30 second. Reflow Zone (D) — The profile in the figure is designed for Sn/Ag3.0/Cu0.5. It can be a reference for other lead-free solder. The peak temperature should be high enough to achieve good wetting but not so high as to cause component discoloration or damage. Excessive soldering time can lead to intermetallic growth which can result in a brittle joint. The recommended peak temperature (Tp) is 230 ~ 250 °C. The soldering time should be 30 to 90 second when the temperature is above 217 °C. Cooling Zone (E) — The cooling ate should be fast, to keep the solder grains small which will give a longerlasting joint. Typical cooling rate should be 4 °C.
