ESP8266 Wireless module NodeMCU V3

RWF 11,000.00

NodeMCU is an open source firmware used to develop a prototype or build IoT devices That firmware is based on the ESP8266 WIFI SoC from Espressif systems and Hardware ESP-12 module. It use the Lua scripting language. NodeMCU is on the eLua project and built on Espressif Non-OS SDK for ESP8266


NodeMCU V3 Features
  • Open-source
  • Arduino-like hardware
  • Status LED
  • MicroUSB port
  • Reset/Flash buttons
  • Interactive and Programmable
  • Low cost
  • ESP8266 with inbuilt wifi
  • USB to UART converter

Power input:

  1. Motor power supply (VM): 4.5V ~ 36V, can be powered separately
  2. Control power (VIN): 4.5V ~ 9V (10VMAX), can be powered separately
  3. Module provides short-circuit sub (short the VM and VIN), you can easily use one power (must 4.5V ~ 9V) while completing motor drive and control
  4. Logic Operating current Iss: ≤60mA (Vi = L), ≤22mA (Vi = H)
  5. Drive part of the work current Io: ≤1.2A
  6. Maximum power dissipation: 4W
  7. Control signal input level: High: 2.3V≤VIH≤VIN; Low: -0.3V≤VIL≤1.5V
  8. Drive Type: Dual high-power H-bridge driver
  9. ESP12E Dev Kit Control Port: D1, D3 (A motor); D2, D4 (B motor)
  10. Expand two-way motor-driven, two-way direct drive motor
  11. Onboard power switch
  12. Motor power, control power separation; In the experiment, by short-circuiting block the merger,
  13. the VIN and VM short, while power to the motor and the control board

Package include:

1 x ESP8266 NodeMCU
