This is the first motor-driven expansion board that based on ESP- 12E development platform. When inserting ESP-12E module, please note the direction consistent with an expansion board antenna; The use of short modules that can simultaneously control board and motor.


  • ESP12 DEV KIT development board expansion module;
  • lead ESP12 DEV KIT all the features of pins: SPI, UART, GPIO, AI and 3.3V power connector;
  • extend two-way motor-driven, two-way direct drive motor;
  • onboard power switch;
  • L293D
  • Motor power, control power separation; In the experiment, a short circuit can block the merger, shorted to VIN and VM, while power supply to the motor and the control board.


  • Motor Power Range: 4.5V ~ 36V;
  • control supply range: 4.5V ~ 9V
  • Logical operating current Iss: ?60mA (Vi = L), ?22mA (Vi = H);
  • Driving part of the work current Io: ?1.2A;
  • Maximum power dissipation: 4W (T = 90 ?)
  • Control signal input level: High: 2.3V?VIH?VIN; Low: -0.3V?VIL?1.5V
  • Operating temperature: -25 ? ~ + 125 ?
  • Drive Type: Dual high-power H-bridge driver
  • ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
