Code

Wiring

Action Wiring
  • Boot pin D4 to MCU like arduino
  • Or turn on board by pressing key manually
D4 pin -> KEY (BOOT) pin
Soft UART connection arduino D2 D3 -> TXD and RXD
Power Supply
  • 5V via diode to VBAT pin, GND to GND
  • Diode not necessary for testing, but need for final project

Demo runing video please see here., one time per second blink 1PPS LED, slow blink when network registed network LED.

Note

  • For GPS location, must leave the antenna fully out of artitecture, at outdoor environment.
