Review on Wireless Quad-Band GSM/GPRS/GPS Shield Based On SIM808 Onboard CP2102 MIC29302 Phone Talk Speaker Module @XYGStudy by Adam Wilson
Worked fine for 4 months and died.
I have had the unit for about 4 months in a sitting position with occasional use, powered by a stable power source. Unfortunately it suddenly doesn't seem to work anymore and doesn't show up in dmesg or /dev/ anymore.
- Easy to read control panel
- There are cons
