Accompany Module
hardware Setup
- arduino pro mini 5V/16M
- SIM800 software serial port, selected by SMD jumper: D2 + D3 or D4 + D5
- pull D8 pin to HIGH for at lease 2 seconds, and then LOW to boot SIM800 module
- SIM800 Network LED should start to link

- Please use as a refernece, the repository may need sort out.
Programming
- You will need CP2102 or FT232RL, etc, connect 5V, GND, TX, RX, RST to board relevant pin 5V, GND, RX, TX and DTR.
- A standard FTDI connector wiring image could see here.
- Board pre flashed with arduino pro mini 5V/16M firmware, please choose this as board, and free to upload new code.
Note
- Notice: current board can not fit into our relay board case, AC-DC unit is too big, will make next version supported.
