What are the pinout mappings? (XPAND, FTDI, ISP)

XPAND:

Starting with Pin 1 and moving counter-clockwise:

• 5V+
• PC0 (ADC0/PCINT8)
• PC2 (ADC2/PCINT10)
• PC4 (ADC4/SDA/PCINT12)
• PC5 (ADC5/SCL/PCINT13)
• PC3 (ADC3/PCINT11)
• PC1 (ADC1/PCINT9)
• GND

FTDI:

Left to right, starting with the pin marked GRN:

• PC6 (Reset/PCINT14)
• PD1 (TXD/PCINT17)
• PD0 (RXD/PCINT16)
• 5v+
• GND
• GND

ISP:

Starting with Pin 1 and moving counter-clockwise:

• PB4 (MISO/PCINT4)
• PB5 (SCK/PCINT5)
• PC6 (RESET/PCINT14)
• GND
• PB3 (MOSI/OC2A/PCINT3)
• 5V+
