DEVELOPMENT BOARDS & PROTOTYPING

• Features of IR Sensor Module:-  
  • When the module detects obstacles in front of the signal, the circuit board green indicator light level, while the OUT port continuous output low-level signals, the module detects a distance of 2 ~ 10cm, detection angle 35 °, the detection distance can be potential adjustment with adjustment potentiometer clockwise, the increase in detection distance; counterclockwise adjustment potentiometer, the detection distance decreased.
  • the sensor active infrared reflection detection, target reflectivity and shape of the detection distance of the key. The black minimum detection range, white maximum; small area object distance is small, a large area from the large.
  • The sensor module output port OUT can be directly connected with the microcontroller IO port can also be driven directly to a 5V relay; Connection: VCC-VCC; GND-GND; OUT-IO.
  • The comparator using LM393, stable.
  • 3-5V DC power supply module can be used. When the power is turned on, the red power LED is lit.
  • With the screw holes of 3mm, easy to install.
  • Board size: 3.1CM * 1.5CM.
  • Each module in the delivery has threshold comparator voltage adjustable via potentiometer, special circumstances, please do not adjust the potentiometer.
   

• Built-in on-board USB-TTL serial converter based on CH340G, with Micro-USB socket
• Power in for DC 4~9V DC to pin VIN
• Pin headers 2.54mm (0.1") 15 pins x 2 rows
• Arduino-like hardware I/O and can program in Arduino IDE
• Event-driven API for network applications
• 10 GPIOs D0-D10, PWM functionality, IIC and SPI communication, 1-Wire and ADC A0, etc. all in one board
• Wifi networking (can be used as an access point and/or station, host a web server), connect to the internet to fetch or upload data

The board combines features of a WiFi access point and station plus a microcontroller and uses simple Lua-based programming language.

Arduino-like hardware IO

Advanced API for hardware IO, which can dramatically reduce the redundant work for configuring and manipulating hardware. Code like Arduino, but interactively in Lua script.

Nodejs style network API

Event-driven API for network applications facilitates developers writing code running on a 5mm*5mm MCU in Nodejs style. Greatly speed up your IoT application development process.

Lowest cost WI-FI

WI-FI MCU ESP8266 integrated and easy to the prototyping development kit. The best platform for IoT application development at the lowest cost.

Usage Notes:

The ESP8266 uses a lot of current, so if you're getting flakey behavior, make sure you are plugging your console cable into either a motherboard USB port or a powered USB hub. Don't use the 'extra' USB port on your monitor or keyboard.
