pins via one port, P0. Each GPIO can be accessed 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

3.4 Peripheral pin assignments
The peripherals within the BMD-300 may be assigned to nearly any of the GPIO pins through the
application. There are some restrictions called out by the nRF52832 product specification. See the
remarks column of Table 2. Also note that certain peripherals are assigned to particular pins, such
the analog inputs and NFC antenna.
Module reset
GPIO pin P0.21 may be used for a hardware reset. In order to utilize P0.21 as a hardware reset, the
UICR registers PSELRESET[0] and PSELRESET[1] must be set alike, to the value of 0x7FFFFF15.
When P0.21 is programmed as RESET, the internal pull-up is automatically enabled. Nordic
Semiconductor example applications and development kits program P0.21 as RESET_N.
Debug and programming
The BMD-300 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.
The BMD-300 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.
Clocks
The BMD-300 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
nRF52832 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 Bluetooth low energy applications at a reduced cost and slight increase
in power consumption.
☞ The ANT protocol requires the use of an external crystal.

Module programming and read-back protection
For legacy applications, RigDFU allows for UART and OTA updates to RigDFU, the SoftDevice and
application firmware.
In order to utilize the SWD port on “AA” and “AB” marked modules, the nRF52832 must be erased and
recovered. Without this step, the module will not be recognized by most programmers. This is
accomplished through nrfjprog, which is provided with the Nordic Semiconductor command line
utilities:
nrfjprog -f nrf52 ––recover
☞ A full chip erase is performed, so all components will need to be re-loaded (bootloader, SoftDevice,
application firmware, and if used the public Bluetooth device address).
The BMD-300 module may be restored to the factory firmware versions noted above with the utilities
available at our GitHub repositories.
SoftDevices
Nordic Semiconductor protocol stacks are known as SoftDevices. SoftDevices are pre-compiled, prelinked binary files. SoftDevices can be programmed in nRF52 series SoCs and are downloadable from
the Nordic Semiconductor website. The BMD-300 with the nRF52832 SoC supports the S132
(Bluetooth low energy Central & Peripheral), S212 (ANT) and S312 (ANT and Bluetooth low energy)
SoftDevices.

6 RF design notes
Recommended RF layout and ground plane
For the BMD-300, the integrated antenna requires a suitable ground plane to radiate effectively.
The area under and extending out from the antenna portion of the module should be kept clear of
copper and other metal. The module should be placed at the edge of the PCB with the antenna edge
facing out. Reducing the ground plane from that shown in Figure 7 will reduce the effective radiated
power. For example, a 27 mm x 29 mm board (about the size of a coin cell) has approximately 3 dB
lower output than the BMD-300 Evaluation Board.
Figure 7: Recommended RF layout and ground plane
Mechanical enclosure
Care should be taken when designing and placing the BMD-300 into an enclosure. Metal should be
kept clear from the antenna area, both above and below. Any metal around the module can negatively
impact RF performance.
The module is designed and tuned for the antenna and RF components to be in free air. Any potting,
epoxy fill, plastic over-molding, or conformal coating can negatively impact RF performance and must
be evaluated by the customer.
