BMD-341 - Data sheet 2.3 BMD-300 series footprint compatibility and migration Figure 3: BMD-340/341 and BMD-300/301/330/360 Footprint comparison The BMD-341 footprint is identical to the BMD-340 and has been designed to allow for backwards compatibility with the BMD-300, BMD-301, BMD-330, and BMD-360 modules with pins 1 through 47 of the BMD-341 directly mapping to the same pin numbers on the BMD-300/301/330/360.
BMD-341 - Data sheet 2.3.1 BMD-300/301/330/360 to BMD-341 pad differences Due to changes in the nRF52840 SoC used by the BMD-341, not all functions (such as SWO/TRACE signals) are found on the same pins as on the BMD-300/301/330/360. Particularly of note is the reset pin function which on the BMD-341 is now available on P0.18 instead of P0.21 as on the BMD-300/301/330/360. To maintain pin for pin compatibility of the reset signal, P0.18 and P0.21 have swapped pad locations on the BMD-341 footprint.
BMD-341 - Data sheet Using the BMD-341 minimal footprint, with only the additional VCCH pad added, allows BMD-300 designs to gain the following BMD-341 features with typically minor layout re-work: Bluetooth 5 long range modes IEEE 802.15.4 (Thread and Zigbee) connectivity Doubled Flash memory (1 MB vs. 512 KB) Quadrupled RAM (256 KB vs.
BMD-341 - Data sheet 3 Electrical specifications ⚠ Stressing the device above one or more of the ratings listed in the Absolute maximum rating section may cause permanent damage. These are stress ratings only. Operating the module at these or at any conditions other than those specified in the Operating conditions section of this document should be avoided. Exposure to absolute maximum rating conditions for extended periods may affect device reliability.
BMD-341 - Data sheet Normal/Low Voltage (LV) or High Voltage (HV). The voltage present on the VCC pin is always the GPIO high logic level voltage, regardless of power mode. To enter LV Mode, the same source voltage is applied to both the VCC and VCCH pins causing REG0 to automatically shut down leaving only the REG1 stage active. To enter HV, the source voltage is only applied to VCCH causing the VCC pin to become an output source supplied by REG0.

BMD-341 - Data sheet Figure 10: BMD-340/341 LiPo-powered HV example with USB charger ⚠ Important: The LiPo circuit above is meant to be a generic example of how the BMD-341’s power modes can be used. Great care must be taken when integrating Lithium-Ion batteries into a design. Protection circuits suitable for the type of battery used and the application must always be implemented. 3.
BMD-341 - Data sheet When P0.18 is programmed as RESET_N, the internal pull-up is automatically enabled. Nordic Semiconductor example applications and development kits program P0.18 as RESET_N. 3.6 Debug and programming The BMD-341 supports the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful mechanism for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace capture of code execution flow are part of this support.
BMD-341 - Data sheet 4 Firmware Projects for the BMD-341 should utilize the Nordic Semiconductor SDK and the nRF52840 tools for new development. This will allow access to the very latest Bluetooth support from Nordic Semiconductor and provide an ongoing path as new features are released. 4.1 Factory image The BMD-341 module is not loaded with a factory firmware image. 4.2 SoftDevices Nordic Semiconductor protocol stacks for Bluetooth and ANT are known as SoftDevices.
BMD-341 - Data sheet 4.2.3 IEEE 802.15.4 (Thread and Zigbee) IEEE 802.15.4 based protocols, such as Thread and Zigbee, on the BMD-341 are not implemented using a SoftDevice. Nordic Semiconductor provides an IEEE 802.15.4 compliant MAC stack which does not require a SoftDevice to be loaded to operate. Nordic Semiconductor also provides pre-compiled Thread and Zigbee stacks. See the Nordic Semiconductor SDK for more information on developing applications that utilize IEEE 802.15.4.
