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.
BMD-345 - 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-345 - Data sheet Mode Pin Name Connection Normal 17 65 VCC VCC 2.0 V to 3.6 V DC Table 8: Power mode pin connections 3.3.1 USB power The USB interface on the BMD-345 can be used when the module is in Normal mode. The BMD-345 USB PHY is powered by a dedicated, internal LDO regulator that is fed by VBUS, pin 66. ⚠ 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. 3.
BMD-345 - Data sheet The BMD-345 also supports ETM and ITM trace. The 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. 3.7 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.
BMD-345 - Data sheet 4 Firmware Projects for the BMD-345 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-345 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-345 - Data sheet 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. Both allow for concurrent operation with Bluetooth low energy SoftDevices. 4.
BMD-345 - Data sheet 5 RF front end – PA / LNA The BMD-345 uses an RF front end that incorporates a power amplifier (PA) and low noise amplifier (LNA) to achieve superior RF performance. The Skyworks RFX2411 PA / LNA IC used to increase TX power and RX sensitivity, providing a significantly increased link budget for long range connections. This section covers how to configure the RFX2411 via GPIO for radio operation.
