Arduino Pin Assignment Overview

I'm posting here an overview of the pin assignment and cable colors for my box. It's based on the very nice pinout diagram from [1].

Channel	Pulse level	Pulse direction	LED	Channel pull	Current sensing
	yellow	orange, green		blue	pink
A	PWML4 (pin 9)	PWML0 (pin 34), PWMH0 (pin 35)	PIOD9 (pin 30), red	PIOC12 (pin 51)	AD7 (pin A0)
B	PWML5 (pin 8)	PWML1 (pin 36), PWMH1 (pin 37)	PIOA7 (pin 31), yellow	PIOC13 (pin 50)	AD6 (pin A1)
C	PWML6 (pin 7)	PWML2 (pin 38), PWMH2 (pin 39)	PIOD10 (pin 32), green	PIOC14 (pin 49)	AD5 (pin A2)
D	PWML7 (pin 6)	PWML3 (pin 40), PWMH3 (pin 41)	PIOC1 (pin 33), blue	PIOC15 (pin 48)	AD4 (pin A3)

As you can see, I've made provisions for four output channels. I've also added the rotary encoder pins (PIOD0-2, pins 25-27), the ST7735 display (pins 2-4 and SPI header pins), the line-in audio on AD0 (pin A7), and an ESP8266 WiFi chip on Serial3 as a future extension for communication with the outside world.
