GBoard Arduino SIM900 GSM GPRS Module Board ATMega328P For Home Automation or Robot Control
- Product Review (submitted on March 6, 2013):
- This is an excellent board to start with, however, you may find yourself out of the SRAM (only 2K available on 328P). It would be excellent, if this would have the ATMEGA 1280 - just like Arduino MEGA... This design actually more preferable than mega+SIM900 shield, as the shield uses the 5V supplied by Arduino - meaning SIM900 will never be able to get 3A from arduino board, but THIS specific GBOARD actually solves this issue - full 3A available to SIM900!!! - the only drawback is the smaller CPU...
