The JD humanoid has 4 processors, not 2. I believe the stats of which you are inquiring are of the EZ-B v4, which is one of the components of the JD Humanoid.

EZ-B v4

• STM Arm Cortex-M3 handles digital i/o, pwm, servos, uart, audio
• Pic32 hosts wifi communication, tcp/stack and communication protocol

JD Head

• STM Arm Cortex handles video codec and buffering from the camera
• Microchip Pic 16f handles the programmable 18 RGB LED PCB for the eyes of JD

Excuse me,are schematic and firmware open source?

No.

Correction. The code for the pic32 is open source, so you can modify the wifi behavior. See https://synthiam.com/Products/ARC
