1. Introduction

BluNor BC840 Series are powerful, highly flexible, ultra low power wireless modules using Nordic nRF52840

transceiver, and an integrated antenna, it allows faster time to market with reduced development cost.

The following is a block diagram of BC840. Antenna circuit and main clock are integrated. All 48 GPIOs of

nRF52840 can be accessed from main board. For lower power consumption at idle state, a 32.768 kHz crystal

can be added on the host board. Connection to an external NFC (Near Field Communication) antenna is

provided.
