Figure 2： Power Supply PCB Design
6.2. PIO
The general purpose I/O is organized as one port with up to 19 I/Os (dependent on package)
enabling access and control of up to 19 pins through one port. Each GPIO can be accessed
individually with the following user configurable features:
 Input/output direction
 Output drive strength
 Internal pull-up and pull-down resistors
 Wake-up from high or low level triggers on all pins
 Trigger interrupt on all pins
 All pins can be used by the PPI task/event system.
The maximum number of pins that can be interfaced through the PPI at the same time is limited
by the number of GPIOTE channels. All pins can be individually configured to carry serial
interface or quadrature demodulator signals.
6.3. AIO
The 10 bit incremental Analog to Digital Converter (ADC) enables sampling of up to 8 external
signals through a front-end multiplexer. The ADC has configurable input, reference presaging,
and sample resolution (8, 9, and 10 bit)
6.4. PWMs
The module has 4 independently configurable PWM instances.
6.5. UART
The module has 1 UART interface. The Universal Asynchronous Receiver/Transmitter offers
fast, full-duplex, asynchronous serial communication with built-in flow control (CTS, RTS)
support in hardware up to 1Mbps baud. Parity checking is supported. The GPIOs used for each
UART interface line can be chosen from any GPIO on the device and are independently
configurable. This enables great flexibility in device pinout and efficient use of board space and
signal routing.

8. 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 via 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.

Soldering Recommendations
EH-MC30 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.
SMT stencil making requirements
 If bluetooth module PIN pitch ≥ 0.25mm and other component PIN pitch ≥
0.25mm ,so you choose SMT stencil thickness 1.5mm。
 If bluetooth module PIN pitch ≥ 0.25mm and other component PIN pitch ≤
0.25mm ,so you choose SMT Ladder stencil Bluetooth module thickness
1.5mm other component thickness 1.3mm .
 Solder pad open via ratio Length 1:1.2, width 1:1.

FCC/IC Statements
(OEM) Integrator has to assure compliance of the entire end-product incl. the integrated RF Module.
For 15 B (§15.107 and if applicable §15.109) compliance, the host manufacturer is required to
show compliance with 15 while the module is installed and operating.
Furthermore the module should be transmitting and the evaluation should confirm that the module's
intentional emissions (15C) are compliant (fundamental / out-of-band). Finally the integrator has
to apply the appropriate equipment authorization (e.g. Verification) for the new host device per
definition in §15.101.
Integrator is reminded to assure that these installation instructions
will not be made available to the end-user of the final host device.
The final host device, into which this RF Module isintegrated" hasto be labelled
with an auxilliary lable stating the FCC IDofthe RF Module,such as
"Contains FCC ID:2ACCRMC30
"This device complies with part 15 of the FCC rules. Operation is subject to the following two
conditions:
(1)this devicemay not cause harmful interference, and
(2)this devicemust accept any interference received, including
interference thatmay cause undesired operation."
"Changes or modifications to this unit not expressly
approved by the party responsible for compliance could
void the user’s authority to operate the equipment."
the Integrator will be responsible to satisfy SAR/ RF Exposure requirements,
when the module integrated into the host device.
The final host device, into which this RF Module isintegrated" hasto be labelled
with an auxilliary lable stating the IC ofthe RF Module,such as
"Contains transmitter module IC:20625-EHMC30
This device complies with Industry Canada licence-exempt RSS standard(s). Operation is
subject to the following two conditions:
