Hi,
I bought nRF51822 Evaluation Kit and would like to blue wire an external MCU( Kinetis Cortex-M) to talk to the SoC. It looks like the SoC on this board has many GPIOs access but I'm not sure which one could make a serial communication with an external MCU. Does anyone have any suggestion?
Edited: I think I see SB9-SB12 UART path on the board that could be used to talk to nRF51822. Can someone verify this is OK to blue wire another MCU instead of the Atmel (SEGGER)?
