CHARGE CONTROLLER

#66 XH-M603 Battery Charge Module + Display

Charge controller board

The XH-M603 module is perfect for building a battery charging station, offering a range of protection features and easy to set min/max charging voltages. As soon as the desired battery float voltage is reached, the charging circuit is disconnected.

  • Input Voltage: DC 10-30V
  • Display Precision: 0.1V
  • Control Precision: 0.1V
  • Output Type: directly output
  • Voltage Tolerance: ±0.1V
  • Board Size: 82 x 58 x 18mm

Example of usage:

Plug into battery in order to power the pcb board.

Don’t connect the charge input yet…

Start charge setting (left button)

Press and hold the left button until the LCD starts flashing.

Now press to choose the desired voltage.

Leave the button until flashing stops and the chosen voltage will be set.

Stop charge setting (right button)

ESP8266 DEV BOARD

#65 ESP8266 DEV BOARD

Board

This is an ESP8266 equipped with 32M of flash memory. It is compatible for NodeMCU board (Lua based ESP8266). The additional memory this unit has allows for bigger projects with complicated and large libraries. It features an onboard USB-TTL Serial converter (CH340G chip) and a Micro-USB female connector. It comes with two sets of 15 pins headers to give you the freedom of choosing whether soldering directly onto the pin holes for a more compact approach.

  • Capable of WIFI networking (IOT): Access-Point, station or Web Server etc.
  • Uses simple LUA based programming language
  • Supports Arduino IDE
  • Event-driven API for network applications
  • 9 GPIO pins D0 – D8 featuring PWM functionality, I2C and SPI communication
  • Operating Voltage: 4.9 – 9 VDC
  • Dimensions: 49 x 26 x 5mm
  • Weight: 10g
