# JTAG Interface
|
||||
|
||||
When connecting the MCU to the programmer via the JTAG interface, it is possible for a local power supply connected to the MCU to be used or for power from the debugging/programming adapter to be used. Since having power supplied to the MCU from the debugging/programming adapter can be useful for use outside of the Sunseeker vehicle, we chose to use that.

# Microcontroller Connections

The board is going to be organized to the best of our abilities to be organized as such:

- Peripherals for communicating with/controlling the Sunseeker vehicle
|
||||
- Right Side:
|

In addition to trying to keep the MCU and PCB organized with the left-side being to do with the Sunseeker vehicle and the right side to be peripherals interacting with users, we tried to also load-balance the USCI modules, as well as have the SPI protocol be used in more high data-rate peripherals and I2C used with lower or less-used peripherals. In Texas Instruments SLAS655G Document [Page 7] has a pin diagram showing the physical location of where each pin is physically located.
