common available tools, such as the Keil software development environment and the Segger J-Link
programmer.
Please refer to “N5 Starter Kit User Manual” from Dynastream Innovations for reference software setup
and use with ANT using the Keil software and a J-Link programmer. (Note: this documentation reference
will be updated in the final datasheet revision.)
7.5.2 Initializing the SoftDevice
The D52 module comes with a 20ppm onboard 32 kHz crystal. When initializing the SoftDevice, it is
important to set the crystal accuracy to be 20ppm. This clock source is selected when enabling the
SoftDevice via the sd_softdevice_enable command.
7.5.3 Configuring the dc/dc converter
The D52 module can make use of the DC/DC Converter on nRF52832 chips. This can improve power
consumption under certain conditions.
7.6 Design considerations
RF performance is always affected by the environment. Good design makes a product less susceptible to
adverse conditions. The recommendations in this section are guidelines only; you should thoroughly test
your products in the intended use case environments and make necessary modifications and trade-offs.
For design assistance purposes, a STEP model package and Altium library will be available for product
release.
7.6.1 M4 (D52Q) module mounting
Guidance and diagrams will be provided for final product release.
7.6.2 M6 module mounting
The mating socket is Molex 52991-0208.
7.7 Assembly Considerations
7.7.1 Moisture Control
The module is rated at level 3 (MSL3) as defined by IPC/JEDEC J-STD-020.
To ensure good solderability of the PCB pads, it is highly recommended to always have the modules
intended for reflow well sealed when in storage.
7.7.2 Solder Stencil Design of D52Q (M4) Module
Stencil diagrams will be available for module variants for final product release.
7.7.3 Cleaning Process
The module is made using no-clean solder paste. No-clean process is recommended.
8 Regulatory Approvals and Compliance
Note: This information is pending certification. Final compliance details will be available following
certification for final release.
