2.2 Reference PCB Package Design
Figure 2.1 is the reference module package design for baseplate PCB design.
Solder mask openness can be the same size with EMB1061’s pad.
EMB1061’s PCB thickness is 1.0mm.
2.3 DC Power Design
EMB1061’s operation voltage is 1.7~3.6V with typical voltage 3.3V. The peak current of the module is about
10mA.
If powered by battery, please pay attention to the max voltage and minimal discharge voltage. For coin cell,
the typical voltage is 3.0V, and the minimal discharge voltage is 2.0V, and in practice it usually end up discharging
at about 2.5V. For example, CR2032 coin cell, the discharge characteristics is as below picture. When choosing
EMB1061 Hardware Design Guide
Application Note
[Page 8]
battery, please check whether its discharge characteristics is suitable for EMB1061.
If using DC-DC, DC-DC’s output voltage should be 3.3V, and it’s max current should be above 20mA. PCB
route should be particularly aware for DC/DC power supply. Compact element, excellent connection between
input and output ground, long distance between feedback signal and inductance and Schottky diode are required
for route. Details about the requirements should refer to the datasheet of DC/DC device.
Maximum output current and dissipate heat should be aware for the using of LDO. For example, voltage drop
is 1.7V when voltage reduces from 5V to 3.3V. If the current is 100mA, power consumption is 1.7V *
100mA=170mW. Power Dissipation is a parameter of LDO, which should be over 170mW.
2.4 RF Design
2.4.1 On-board PCB Antenna Design
There should not be components, or ground, or circuit 15mm away from EMB1061’s PCB antenna.
EMB1061 Hardware Design Guide
Application Note
[Page 9]
Figure 2.2 Minimum PCB Clearance Area
In order to reduce the influence from metal components to PCB antenna and wireless signal, it is better to
mount EMB1061 on these areas, as shown in figure 2.3.
Figure 2.3 Position of the Module
2.4.2 External Antenna
Size of connector for external antenna is shown in figure 2.4. Make sure the correct size with suppliers before
buying the connectors of antenna.
EMB1061 Hardware Design Guide
Application Note
[Page 10]
Figure 2.4 Size of connector for external antenna
2.5 ESD Design
ESD level of the module: Human body model (HBM) is 2000V, charged device model (CDM) is 500V.
Position of ESD protected components should be reserved if the products require higher ESD requirement.

3. Downloading Firmware
1. Unzip the package and install the USB driver "CDM 2.08.30 WHQL Certified_64".
2.Power supply to the development board through USB interface. View its corresponding serial port number
from device Manager. 3. Enter BOOTLOADER mode. After confirming that the module is powered (a red LED
lights up next to the USB port), hold down the BOOT button and reset the module through the Reset button, then
release the BOOT button. If the operation succeeds, EMB1061 enters BootLoader mode. 4. Open firmware
upgrade tool software, select module EMB1061, select user serial port number and fix A document.
5. Select the firmware file to upgrade (click the firmware button), and if everything is normal, you will see
the upgrade button brighten. Indicates that you can upgrade. Hover over the firmware button to see the absolute
path of the firmware that has been selected. As shown in the figure:
6. Click the upgrade button and a dialog box will pop up to prompt the user to confirm that the module is now
in BootLoader mode. Click OK to start the upgrade, as shown in figure:
7. After a successful upgrade, the module will automatically Reset and run from the latest firmware. If there
is an error in the upgrade process, the tool will pop up an error prompt, according to which the user can further
process.

4. Important Statement
MXCHIP has a duty to make sure there is no quality problem when sell the module to customers.
Customers have the rights to ask MXCHIP to exchange goods if the product has quality problem.
If the customer find the problem after welding the module on board without testing at the beginning,
MXCHIP is only responsible for the compensation of the module part.
MXCHIP would help customers solve technical problem in developing firmware without save any MVA/bin
file. Customers should save different development vision and download relative vision in module before
producing.

5. SMT
5.1 Stencils
Stencils thickness is suggested to be 0.12mm (0.1~0.15mm) with Laser grinding. Recommended solder paste:
No lead SAC305.
Stencils size is shown in figure 5.1, pad holes extend 0.15mm in order to improving solder wicking. Solder
mask’s width should be 0.1mm wider than stencil’s paste layer, like Pin1 of Figure 5.1. So that if there is no AOI
testing, you can check whether the module is placed well by eye to reduce the Pseudo Soldering.
There is EMB1061’s PCB lib in mxchip.com, and you can use it directly.

5.2 Temperature Curve of Reflow
Pseudo soldering could be reduced by control the furnace with temperature curve of secondary reflow, as
shown in figure 5.2.
Secondary reflow times should be less than twice.
