Power Supply
BlueMod+S42M require a power supply with the following characteristics: Typical: 3,0VDC, min.: 1,8VDC, max.: 3,6VDC, thereby delivering > 25 mA peak BlueMod+S42M is designed to be powered from 3V coin cell batteries e.g. CR2032 directly,
or any other power source complying with the given requirements. For optimal performance, a stable supply is recommended. Furthermore, it is recommended to place a capacitor in parallel to the CR2032 3V coin cell battery in order to prolong battery lifetime, by compensating the effects of the rising source resistance of the battery to pulsed loads. Since the isolation resistance of this capacitor will discharge the battery in a not insignificant scale, the capacitor should be chosen under consideration of the following rules:
• capacitance as small as necessary
• nominal voltage as high as possible
• case size as large as possible
• use X7R instead of X5R

Serial Interface
The serial interface of BlueMod+S42M is a high-speed UART interface supporting RTS/CTS flow control and interface-up/down mechanism according to the UICP+ protocol (refer to [2]).
Electrical interfacing is at CMOS levels (defined by VSUP; see chapter 6.4.1). Transmission speeds are 9600 – 921600 bps and 1Mbps (asynchronous). Character representation: 8 Bit, no parity, 1 stop bit (8N1). Hardware flow-control with RTS and CTS (active low).
Transmission speed may be limited by firmware. See corresponding AT command reference [3] for further information.
4.3.1. Basic Serial Interface
The basic serial interface (with RTS/CTS flow control) uses only four signal lines (UART­RXD, UART-TXD, UART-CTS#, UART-RTS#) and GND. IUR-IN#, IUR-OUT# and GPIO[4] (see below) can be left unconnected.

Figure 6: Basic Serial Interface
If the host in question is sufficiently fast, a four-wire scheme may be successful. Connect the serial lines UART-RXD, UART-TXD as well as UART-RTS# and GND; leave UART­CTS# open. The host is required to stop sending data within a short time after de-assertion of UART-RTS# (there is room for up to 4 more characters at the time RTS# drops).
UICP has to be deactivated permanently in this configuration, because signal UART-CTS# and IUR-IN# become inputs with no PU or PD if UICP is active. This would cause floating CMOS inputs.
It is strongly recommended to use hardware flow control in both directions. Not using flow control can cause a loss of data.
BlueMod+S42M Hardware User Guide
4.3.2. Serial Interface with UICP
A substantially saving of power during idle phases can be achieved (see 6.5.1) when the UICP protocol is used (refer to [2]). This protocol should be implemented on the host side as well. Signals IUR-IN# and IUR-OUT# should be connected to the host and may be mapped to DSR and DTR, if an RS232-style (DTE-type) interface is used (see Figure 7).

Figure 7: BlueMod+S42M Example Serial Interface (RS-232) Supporting UICP
If I/O line availability at the host side is extremely tight, 2 I/O lines could be saved by using the following scheme. This would come at the cost of
• The host is not allowed to enter sleep mode.
• The host must accept incoming data at all times and is not able to stop the
BlueMod+Sx sending data. This may be difficult to control for all scenarios and adds the risk that data gets lost.
• The host doesn’t implement UICP, but wake-up BT via GPIO.

I2C Interface
The I2C bus interface serves as an interface between the internal microcontroller and the serial I2C bus. BlueMod+S42M is the master and controls all I2C bus specific sequencing, protocol and timing. It supports standard (100kHz) and fast (400kHz) speed modes. The BlueMod+S42M as an I2C master must be the only master of the I2C bus (no multimaster capability). Clock stretching is not supported.
SDA and SCL can be used to form an I2C interface. It is not required to connect pull-up resistors on SCL and SDA when this interface is used.

Serial Wire Debug Interface
The Serial Wire Debug (SWD) interface (signals SWDIO, SWCLK) is normally not used in a customer’s product. It is reserved for debugging purposes.
Leave SWDIO, SWCLK unconnected. Only if you intend to use them for debugging purposes, make them available.
BlueMod+S42M Hardware User Guide
MEMS Sensors (Optional)
The BlueMod+S42M includes optional an triaxial, low-g acceleration sensor, which integrates a multitude of features that facilitate its use especially in the area of motion detection applications, such as device orientation detection, navigation and spirit level measurements. Featuring 14 bit digital resolution, the sensor allows very low-noise measurement of accelerations in 3 perpendicular axes and thus senses tilt, motion, shock and vibration.
Option: 3A
Furthermore the BlueMod+S42M includes optional an humidity and temperature sensor that provides high accuracy measurements with very low power consumption.
The capacitive-based sensor provides high accuracy measurement capability for a wide range of environmental monitoring applications and Internet of Things (IoT) such as smart thermostats, smart home assistants and wearables. The sensor can also be used to provide critical temperature and humidity data for cold chain transportation and storage of perishable goods to help ensure products like food and pharma- ceuticals arrive fresh.
The sensor is factory-calibrated to 0.2°C temperature accuracy and 2% relative humidity accuracy and includes a heating element to burn away condensation and moisture for increased reliability.
Option: TH
The functionality of both sensors is highly Firmware dependent! Please refer to [4] for further informations.
BlueMod+S42M Hardware User Guide
Test Mode
For regulatory approval purposes, the ability of test mode operation like “Direct Test Mode” (DTM) is mandatory. The Direct Test Mode (as defined by the Bluetooth SIG) is part of the BlueMod+S42M.
For enabling the test mode the BlueMod+S42M provides the Testmode# IO pin. This pin is low active, connect to GND to activate DTM.
To enter and use DTM, access to the following signals is required:
• TESTMODE#
• UART-RXD
• UART-TXD
• UART-RTS#
• UART-CTS#
• GND
These pins shall be routed to some test pads on an outer layer, but can be left open during normal operation when not used.
Please note the UART is required for operation of DTM. For any regulatory approval, UART-RXD, UART-TXD, UART-RTS# and UART-CTS# must be freely accessible.
Operating in a Power-Switched Environment
A potential “back feeding” problem may arise, if the module is operated in an environment
where its power supply (VSUP) is switched off by the application. This might be done to save some power in times Bluetooth is not needed.
As stated in Table 4, the voltage on any I/O pin must not exceed VSUP by more than 0,3V at any time. Otherwise, some current I
INJ
flows through the internal protection diodes. This
may damage the module (please refer to chapter 6.1 for limits). There is no problem if the application circuit design and programming can assure that all
signals directed towards BlueMod+S42M are set to low (U < 0,3V) before and while VSUP is turned off. If this is not guaranteed, at least a series resistor (about 1k) must be inserted into each signal path. This does protect the module but obviously cannot prevent from an unwanted, additional current flow in case of such signal being at high-level. It may be necessary to use driver chips in such applications, that gate off these signals while VSUP is not present.

Opposite side reflow is prohibited due to module weight. Devices will withstand the specified profile and will withstand up to one re-flows to a
maximum temperature of 260°C. The reflow soldering profile may only be applied if the BlueMod+S42M resides on the PCB side looking up. Heat above the solder eutectic point while the BlueMod+S42M is mounted facing down may damage the module permanently.
BlueMod+S42M Hardware User Guide
Placement Recommendation
To achieve best radio performance for BlueMod+S42M, it is recommended to use the placement shown in Figure 17. This is a “corner placement” meaning the module is placed such that the antenna comes close to the corner of the application PCB (red area). So, the yellow area is outside the PCB and regards to the housing, too (refer to 7.6).
Please note that for best possible performance the antenna should be directed away from the application PCB as shown in Figure 17.

Antenna Issues
BlueMod+S42M comprises a ceramic antenna, which as a component is soldered to the circuit board. The performance of the antenna has to be checked within the final integration environment. Adjacent PCBs, components, cables, housings etc. could otherwise influence the radiation pattern or be influenced by the radio wave energy.
Housing Guidelines
The individual case must be checked to decide whether a specific housing is suitable for the use of the internal antenna. A plastic housing must at least fulfill the following requirements:
• Non-conductive material, non-RF-blocking plastics
• No metallic coating
• ABS is suggested
Safety Guidelines
According to SAR regulation EN 62479:2010 the BlueMod+S42M is not intended to be used in close proximity to the human body. Please refer to above-mentioned regulation for more specific information.
In respect to the safety regulation EN 62368-1:2014 + AC:2015 all conductive parts of the BlueMod+S42M are to be classified as SELV circuitry. OEM’s implementing the BlueMod+S42M in their products should follow the isolation rules given in regulation EN 62368-1:2014.
The PCB material of the BlueMod+S42M is classified UL-94V0.
BlueMod+S42M Hardware User Guide
Cleaning
In general, cleaning the modules mounted on the host board is strongly discouraged. Residues between module and host board cannot be easily removed with any cleaning method.
• Cleaning with water or any organic solvent can lead to capillary effects where the
cleaning solvent is absorbed into the gap between the module and the host board. The combination of soldering flux residues and encapsulated solvent could lead to short circuits between conductive parts. The solvent could also damage any labels.
• Ultrasonic cleaning could damage the module permanently. Especially for crystal
oscillators the risk of damaging is very high.
8. APPLICATION DIAGRAM
Figure 18 shows a typical application of BlueMod+S42M. The module is connected to some MCU running the application layer. MCU and BlueMod+S42M use the same 3,3V power supply. The serial interface has RTS/CTS flow control and UICP support in this example. The optional hangup feature to close down the link is provided.
All other module pins may be left unconnected.
