BMD-345 Module for Bluetooth 5 and 802.15.4
The BMD-345 is an advanced, highly flexible, ultra-low power multiprotocol SoM that enables Bluetooth 5 (BLE) and
IEEE 802.15.4 (Thread and Zigbee) connectivity for portable, extremely low power embedded systems. With an ARM®
Cortex™-M4F CPU, integrated 2.4GHz transceiver, and an integrated antenna, the BMD-345 provides a complete RF
solution allowing faster time to market with reduced development costs. Providing full use of the Nordic nRF52840’s
capabilities and peripherals, the BMD-345 can power the most demanding applications, all while simplifying designs
and reducing BOM costs. The BMD-345 is an ideal solution for designs that require the latest Bluetooth 5 features or
802.15.4 based networking for Thread. Increased integration with built in USB and 5.5V compatible DC/DC supply
reduces design complexity and BOM cost, while expanding possible applications. BMD-345 designs are footprint
compatible with the BMD-301, providing low-cost flexibility for tiered product lineups.

Note 1: An internal 4.7µF bulk capacitor is included on the module. However, it is good design practice to add additional bulk
capacitance as required for your application, i.e. those with heavy GPIO usage and/or current draw.
Note 2: These pins are in close proximity to the nRF52 radio power supply and antenna pins. Radio performance parameters, such
as sensitivity, may be affected by high frequency digital I/O with large sink/source current on these pins. Nordic recommends using
only low frequency, low-drive functions when possible.
Note 3: In HV mode, VCC acts as a regulated supply that can power other external devices. The voltage output of VCC can be
configured in software but is limited to no more than VCCH-0.3V. In System Off mode VCC can supply no more than 1mA.

4.2 Peripheral Pins
The BMD-345 features a pin muxing system that allows most internal peripherals, such as UART and SPI, to be
used on any GPIO pin. This freedom in pin choice enables better optimization of designs and PCB layout. Note that
only one peripheral signal can be muxed to a GPIO pin at a time. Some functions are restricted to certain pins due
to additional internal circuitry required by the interface. These include: Trace signals, analog inputs, XTAL signals,
USB signals, SWD interface, and reset. See Table 3 below for details:

Note: Some peripherals on the BMD-345 share the same memory location for their registers. This means that only
one of these peripherals can be used at a time. It is possible to switch between peripherals that share the same
register location by clearing and reinitializing the associated configuration registers. See the Nordic Semiconductor

4.2.1 BMD-301 to BMD-345 Pad Differences
Due to changes in the nRF52840 SoC used by the BMD-345, not all functions (such as SWO/TRACE signals) are
found on the same pins as on the BMD-301. Particularly of note is the reset pin function which on the BMD-345 is
now available on P0.18 instead of P0.21 as on the BMD-301. To maintain pin for pin compatibility of the reset
BMD-345 V1.0 CONFIDENTIAL Page 9 of 20
signal, P0.18 and P0.21 have swapped pad locations on the BMD-345 footprint. These differences are detailed in

5.3 Power Configuration
5.3.1 USB Power
The BMD-345 USB PHY is powered by a dedicated, internal LDO regulator that is fed by the VBUS pin (66). This
means that applying power to only the VBUS pin will not power the rest of the module. In order for the USB PHY
to operate, VBUS must be externally powered.
5.4 General Purpose I/O
The general purpose I/O is organized as two ports enabling access and control of the 48 available GPIO pins. The
first port allows access of P0.00 to P0.31, similar to the one port available on the BMD-301. The second port, new
to the BMD-345, allows access to P1.00 to P1.15. 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

5.6 Debug & Programming
The BMD-345 supports the two pin Serial Wire Debug (SWD) interface and offers flexible and powerful
mechanisms for non-intrusive debugging of program code. Breakpoints, single stepping, and instruction trace
capture of code execution flow are part of this support.
The BMD-345 also supports ETM and ITM trace. Trace data from the ETM and the ITM is sent to an external
debugger via a 4-bit wide parallel trace port. In addition to parallel trace, the TPIU supports serial trace via the
Serial Wire Output (SWO) trace protocol.

5.7 Clocks
The BMD-345 requires two clocks, a high frequency clock and a low frequency clock.
The high frequency clock is provided on-module by a high-accuracy 32-MHz crystal as required by the
nRF52840 for radio operation.
The low frequency clock can be provided internally by an RC oscillator or synthesized from the fast clock; or
externally by a 32.768 kHz crystal. An external crystal provides the lowest power consumption and greatest
accuracy. Using the internal RC oscillator with calibration provides acceptable performance for BLE
applications at a reduced cost and slight increase in power consumption. Note: the ANT protocol requires the
use of an external crystal.

5.8 MAC Address Info
The BMD-345 modules comes preprogrammed with a unique MAC address from the factory. The MAC
address is also printed on a 2D barcode on the top of the module.
Figure 3 – BMD-345 MAC Address on Label
The 6-byte BLE Radio MAC address is stored in the nRF52840 UICR at NRF_UICR_BASE+0x80 LSB first. Please
read the MAC Address Provisioning application note if you are not using the built in bootloader to avoid
erasing/overwriting the MAC address during programming. Important: If full memory protection is enabled,
the UICR cannot be read via the SWD interface. If performing a full-erase, the MAC can then only be recovered
from the 2D barcode and human-readable text.
UICR Register:
NRF_UICR + 0x80 (0x10001080): MAC_Addr [0] (0xZZ)
NRF_UICR + 0x81 (0x10001081): MAC_Addr [1] (0xYY)
NRF_UICR + 0x82 (0x10001082): MAC_Addr [2] (0xXX)
NRF_UICR + 0x83 (0x10001083): MAC_Addr [3] (0x93)
NRF_UICR + 0x84 (0x10001084): MAC_Addr [4] (0x54)

7. Bluetooth Qualification
The BMD-345 Series modules will be qualified as a Bluetooth Component (tested) for RF-PHY. This allows
customers to use different SoftDevices that have been qualified by Nordic without the need to complete
additional RF-PHY testing. To achieve Bluetooth End Product qualification, the Rigado RF-PHY QDID can be
combined with Nordic QDIDs for the SoftDevice used when filing on the Bluetooth SIG website. The only
testing required is for the Bluetooth profiles supported by the customer’s product. Products with only custom
profiles do not require any additional testing.
