Pin Headers, J1, J2, J3, and J4 on board provide access to all Main MCU interface signals, and to voltages
for all Main MCU power ports.
On the EK-RA4M1, 40 pins of the pin headers are set aside for fixed function assignment. These pins are
odd-numbered pins of J1 and even-numbered pins of J2.
Pin Header Fixed Function Pins are labeled with dark text on a white background. Pins that are not Fixed
Function pins are labeled with white text on a dark background. On the top side of the board is the functional
label for the fixed location. On the bottom side of the board is the port information for the same pin.

Primary Fixed Function Pins share the same functionality across EK-RA6M1, EK-RA6M2, EK-RA4M1, and
EK-RA2A1 boards.
Secondary Fixed Function Pins share common pin assignments with other Renesas RA Family Evaluation
Kits that have Main MCUs with the same functionality. The Secondary Fixed Function Pins are also labeled
with the top side having a functional label, and bottom side having a port label.
