BMD-380 - Data sheet 2.2 Peripheral pins The BMD-380 features a pin multiplexing 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. ☞ Only one peripheral signal can be multiplexed to a GPIO pin at a time. Some functions are restricted to certain pins due to additional internal circuitry required by the interface.
BMD-380 - 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-380 - Data sheet 3.3 Power and DCDC configuration ☞ The BMD-380 is based on the nRF52840, revision 2 or newer IC. The BMD-380 has two internal regulator stages that each contain an LDO and DCDC regulator. The first regulator, REG0, is fed by the VCCH pin and can accept a source voltage of 2.5 V to 5.5 V. The output of REG0 is connected to the VCC pin and the input of the second regulator stage REG1. REG1 supplies power to the module core and can accept an input source voltage of 1.7V to 3.6V.

BMD-380 - Data sheet 4 Firmware Projects for the BMD-380 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-380 module is not loaded with a factory firmware image. The unique, public IEEE Bluetooth device address is printed on the module label and is also programmed into the UICR. 4.
BMD-380 - Data sheet 4.3 IEEE 802.15.4 (Thread and Zigbee) IEEE 802.15.4 based protocols, such as Thread and Zigbee, on the BMD-380 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.

BMD-380 - Data sheet 6 RF design notes 6.1 Recommended RF layout and ground plane 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 11 will reduce the effective radiated power.
BMD-380 - Data sheet 6.3 Antenna patterns Antenna patterns are based on the BMD-380 Evaluation Kit with a ground plane size of 109 mm x 56 mm. The X-Y-Z orientation is shown in Figure 12: Figure 12: X -Y-Z antenna orientation 6.3.
