2.7 Preparing the Blueboard for the use with SPI or I
2
C
The Blueboard is generally delivered in I²C configuration, for this reason one only needs
to change the configuration if the use of the board in SPI configuration is desired.
From Blueboard version 3.0 on the layout slightly changed. So we provide two different
descriptions for changing the interface between I²C to SPI. Since version 3.0 the
standard interface switched to the SPI interface.
2.7.1 Blueboard version 2.1 and below
There are exactly six solder bridges to change.
1. Open the bridge at R18
2. Open the bridge at R15
3. Open the bridge at R11
4. Close the bridge at R17
5. Close the bridge at R14
6. Close the bridge at R12
See the picture of the Blueboard in SPI configuration below.
