1. Introduction
BluNor BT40F Series are powerful, highly flexible, ultra low power wireless modules using Nordic nRF5340
SoCs. With a dual core ARM
Cortex
TM
M33 MCU, embedded 2.4GHz multi-protocol transceiver, and an
integrated antenna, it allows faster time to market with reduced development cost.
BT40F Block Diagram
The following is a block diagram of BT40F. Antenna circuit and main clock are integrated. All 48 GPIOs of
nRF5340 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.
BlurNor BT40F is a sister module of BT840F, an nRF52840 module. The
physical size is the same.
There are 3 modules in the BT40F Series.
