Datasheet

Bluefruit LE SPI Friend
If you have a stand-alone module, you have
a bit of flexibility with wiring however we
strongly recommend Hardware SPI, CS = 8,
IRQ = 7, RST = 4
You can use this with just about any
microcontroller with 5 or 6 pins
Bluefruit LE UART Friend or Flora
BLE
If you have a stand-alone UART module
you have some flexibility with wiring.
However we suggest hardware UART if
possible. You will likely need to use the
flow control CTS pin if you are not using
hardware UART. There's also a MODE pin
You can use this with just about any
microcontroller with at least 3 pins, but best
used with a Hardware Serial/UART capable
chip!
