Module Specification Notes:
Note 1
DSR, DTR, RI, and DCD can be implemented in the smartBASIC application or through the Nordic SDK.
Note: Nordic SDK is not supported on the BL654 USB dongle, part #451-00003.
Note 2
With I2C interface selected, pull-up resistors on I2C SDA and I2C SCL must be connected externally as per I2C
standard.
Note 3
Use of the internal DCDC convertor or LDO is decided by the underlying BLE stack.
Note 4
Nordic Errata 197 and 202 related to the use of VDD_HV DCDC convertor, for details refer to
http://infocenter.nordicsemi.com/pdf/nRF52840_Rev_1_Errata_v1.1.pdf. Nordic Errata 202 means no external
current draw (from VDD pin) is allowed during power up and VDD_HV rise time (to 3V) is below one mS.
