Raspberry Pi Zero W + SIM808 Breakout Board
Posted: Thu Sep 21, 2017 8:31 pm
Hello everyone,
I am kind of new to RPi but I am liking it very much...
I've setup RPi Zero W with no problems whatsoever (using SSH and/or VNC for connecting to RPi).
The OS is Raspbian, fully updated (update, upgrade, firmware..)
I am wondering if it is possible to use this breakout board :

I've got the basics such as connecting TX to RX and vice versa..
Since the resources on using this particular board are scarce, I am asking for your opinion and help throughout connecting it to RPi Zero W.
Questions so far:
1. Are SIM808 TX and RX pins compatible with PIs pins?
2. Can PI power this module? (I am powering PI using USB->MicroUSB, I'm thinking it could power the module using 5V PI pin)
3. What's the 2nd GND on GSM module for? Should they both be connected to GNDs on RPi?
Thanks for your time and help in advance! I am new to this thing so please bear with me
