mBot pin mapping

#1

Not sure if it was posted already, but these are the pins I identified for the mBot, as compared to an Arduino UNO:

A0 RJ25 plug 4 (default not-connected)
A1 RJ25 plug 4 (default not-connected)
A2 RJ25 plug 3 ultrasonic
A3 RJ25 plug 3 ultrasonic
A6 light sensor
A7 button
D2 IR RCV
D3 IR TX
D4 DIR2 - direction motor2
D5 PWM2 - pwm motor2
D6 PWM1 - pwn motor1
D7 DIR1 - direction motor1
D8 buzzer
D9 RJ25 plug 2 linefollower
D10 RJ25 plug 2 linefollower
D11 RJ25 plug 1 (default not-connected)
D12 RJ25 plug 1 (default not-connected)
D13 2 WS2812 RGB leds

To what pins are RGB LEDs attached?

Hi there,
Well done on determining the connectivity.

I also wanted to know the resources and actually located a link to GitHub in another forum post:
https://github.com/Makeblock-official/mBot_Firmata/blob/master/hardware/mCore.pdf

This may not match your hardware - for example it refers to a P6/12 pin header that my mCore does not have (nor unpopulated either).

Unfortunately there is no versioning on either the schematic or the PCB, nor the GitHub repository so we are a little in the dark in this regards.

The pin mapping is actually printed on the back of the mbot board.

#4

is it possiable to use D11 or D12 by other normal wires solder them into the board
