(NOXBLEMOD) into a product as a Bluetooth module. Incorrect integration or use may infringe compliance rules, i.e. recertification may be required. 1.2 Module Description The Nox Bluetooth LE Module (NOXBLEMOD) is a Bluetooth 5.0 and Bluetooth LE module based on a HW solution using the nRF52840 SoC chipset, a QFN package SoC by Nordic Semiconductor. The SoC is capable of concurrent

(simultaneous) central role + peripheral role operation for use cases where connected to multiple sensors as master (central) and connected to mobile device as slave (peripheral). The module contains a Bluetooth PCB F-type antenna, designed for 2.45 GHz. Page 3 of 12 Module Integration 2.1 Module placement on a Carrier Board Below pictures show examples of recommended placements for the Nox Bluetooth LE Module (NOXBLEMOD) on a carrier board (mother board). As can be seen, the module should be placed in a corner for best antenna performance. Figure 1: Examples of good placement of module on carrier board The size of the carrier board should be significantly larger than the module itself as illustrated above, while smaller size may be feasible if the application does not require optimal antenna performance. For completeness also a few examples of bad module placements are illustrated below. As can be understood from below examples is that the antenna of the module should not be oriented as illustrated in below bad examples. 2.2 Figure 2: Examples of poor placement of module on carrier board GND plane removal under Antenna When placing the Nox Bluetooth LE Module (NOXBLEMOD) onto a carrier board there need to be a GND cut out area on the carrier board under the Page 4 of 12 antenna as illustrated below. The GND cut out area shall be on all PCB layers, and no other signals should be routed in this area. 2.3 2.4 Figure 3: Example of GND cut out area under module antenna area Considerations for nearby Materials The placement of the Nox Bluetooth LE Module (NOXBLEMOD) onto a carrier board may depend on the product mechanical design, e.g. plastic housing, placement of any connectors, cables etc. The general recommendation is to try to avoid any material close to the antenna of the module. Especially metal or components containing metal (e.g. batteries) may negatively affect antenna performance, while also plastic material can affect the antenna if placed near the antenna. When possible, keep distance of > 5 mm between antenna and any nearby material. For wearable applications, where the module antenna may be located close to the human body there is a significant risk of poor antenna performance due to body losses. Here, special consideration of the antenna placement and design is typically required. Therefore, the general recommendation is to try placing the module as far as possible from the body in wearable applications. Other PCB related considerations The Nox Bluetooth LE Module (NOXBLEMOD) is designed for robust wireless performance in environments where other interfering radio systems may be present. The Nox Bluetooth LE Module (NOXBLEMOD) exposes all (IO) pins for use in an end product application. The pinout uses 2 rows of pads, implying a multi-layer PCB design if the application makes use of many IO pins. Page 5 of 12 Figure 4 Nox Bluetooth LE Module pin numbering (top view) The assumption is that typically a multi-layer PCB with micro vias is needed, i.e. micro vias used between the outer top layer where the module is placed and the signal layer directly under the top layer. One PCB layer of the carrier board should be a solid GND plane. All GND pads of the module should be connect with a dedicated via to this GND plane. Since the module design include all required decoupling capacitors there are normally not any need for external components, however this may depend on power supply architecture of the application carrier board design. If external capacitors are used these should be placed close to the module for best EMI performance. Even if the nRF52840 based Nox Bluetooth LE Module (NOXBLEMOD) is flexible in how to use GPIO pins, the designer should be aware of the limitations related to general purpose GPIO pins and low speed GPIO pins. When it comes to PCB design and routing ,the signal integrity should be considered. Especially the higher speed interfaces, such as SPI or USB, while Page 6 of 12 low speed control signals and communication interfaces (e.g. I2C) are normally not critical.
