1. PS2X and motor driver board V3.0 based on PCA9685 I2C control chip. Fully stackable design: 5 address select pins means up to 32 stackable shields: 64 stepper motors or 128 DC motors.
2. We now have a TB2612 MOSFET driver instead of the L293D Darlington driver: 1.2A per channel, 3A peak current capability. It also has a lower motor voltage drop so you can get more torque from the battery and have a built-in flyback diode.
3. Drive 4 DC motors or 2 stepper motors, 2 encoder motors, 6 servo motors, two of which can use external power.
With 1 PS2X port, 1 NRF24L01 + module port, 1 ultrasonic module port, 1 Bluetooth and WiFi module port, 1 IIC port, 2 RGB LEDs, 1 buzzer, 1 IR receiver.
4. We provide the Scratch development library, development instructions, driver board schematics and module test procedures, please download the tutorial from the following link:
