The operation is based on the L298 dual full H-bridge. It can independently drive two bidirectional DC motors or one bipolar stepper motor.

Each channel has its own direction selection (D12 and D13), PWM control (D3 and D11), and brake function (D9 and D8). The channels' DC current can be monitored via analog inputs A0 and A1 (3V3@2A).

The current capacity is 2A per channel. Familiarize yourself with the power supply before use.

• four LEDs indicate the channels' polarities
• six auxiliary connectors mainly for Tinker use (I2C, D5, D6, A2, A3)

Note! This shield is +3.3V-compatible in terms of voltage levels.
