Pin to pin compatible, compact and light weight modules and having embedded USB ports, c-uGSM and d-u3G shields (micro) are our latest GSM / 3G-UMTS shields compatible with Arduino, Raspeberry PI, Raspberry PI2 or with any other 2.8-5V micro-controller board.
gSPS adapter it is our "plug and run" SWITCHING POWER SUPPLY for c-uGSM and d-u3G shield.
Next, I will show to you how to speed up your GSM / 3G projects prototyping.
What you will need
- c-uGSM shield (micro) v1.13 1 pcs. or
- d-u3G shield (micro) v1.13 1 pcs.
- g-SPS adapter 4V [DDRV] v1.02 1pcs.
- breadboard 1pcs.
- ..and SIM card, antenna... I will not talk about.
c-uGSM, d-u3G shields and gSPS hardware references
All examples bellow are based on c-uGSM and gSPS 4V [DDRV] (used for direct 3G-GSM shield powering/"NO Lithium Polymer" powering).
NO breadboard differences for gSPS 5V [LiPOL] (used in "WITH Lithium Polymer" powering).
d-u3G diferences - revealed later.
3G/GSM shields reference can be seen here. gSPS switching power supply reference may be found here.
GSM 3G shield breadboard prototyping
Solder the strait row headers to the boards. Solder the barel connector to the gSPS, if needed.
Insert the power supply and the GSM shield as bellow pictures. SIM must be installed to the GSM shield, first. ;)
Between boards, a gap of minimum 5 rows it is requiered. Insulation separator (foam,cardboard,..) must be inserted between boards in order to prevent the SHORT CIRCUITES!
BOARDS MAY BEND WHEN INSERTED AND CAN CAUSE A SHORT CIRCUITS!!! TAKE ALL NECESSARY STEPS TO PREVENT THIS HAPPEN! YOU ARE THE ONLY RESPONSIBLE FOR HARDWARE HANDLING, USAGE AND WIRING!!!
3G shield (d-u3G shield) difference: at insertion moment, ALIGN both sides (TX 2 TX and SLP 2 SLP).
READY! Now you may continue to wire your project, to other boards, starting from the breadboard contacts.
