Description This WiFi RC smart car is designed and developed based on ESP-12F from ESP8266, which can be controlled by mobile, PC. This is motor shield only, you maybe need nodemcu board and a remote car chassis to drive as kit. Based on ESP8266 nodemcu board this one. Please buy this alone. Package ONLY includes the Motor shield, NOT including the nodemcu board. Features: On Board motor drive L293D IC, support to drive two channels of DC motors via screw terminals. Motor power supply (VM): 4.5V ~ 36V, can be a separate power supply; Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately; Module provides short-circuit sub (short the VM and VIN), you can easily use one power (which must be 4.5V ~ 9V) simultaneously drive and control the motor; Otherwise your nodemcu will be burned. Logic Operating current Iess: ≤60mA (Vi = L), ≤22mA (Vi = H); Working current driving portion Io: ≤1.2A; Maximum power dissipation: 4W (T = 90 ℃) Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V Working temperature: -25 ℃ ~ 125 ℃ Drive Type: Dual high-power H-bridge driver Support wireless 802.11 b / g / n standards; Support STA / AP / STA AP three operating modes; Built-in TCP / IP protocol stack to support multiple TCP Client connection (5 MAX); D0 ~ D8, SD1 ~ SD3: used as GPIO, PWM, IIC, etc., port driver capability 15mA; AD0: 1 Road ADC; Current: continuous transmission: ≈70mA (200mA MAX), Standby: <200uA; Transfer rate: 110-460800bps; Support UART / GPIO data communication interface; Remote firmware upgrade (OTA); Smart Link supports intelligent networking capabilities. It can work at many modes, such as: AP mode and STA mode. Documentation, use guide, code see this wiki page.
