G120HDR has been popular since the day it was announced. Thanks to the great feedback, we have upgraded G120HDR while keeping backward compatibility.
The new Rev2 improvements:
[ul]Built in 32.768Khz crystal for RTC
Buttons for LDR1 and LDR2
One of the user sockets is replaced with SPI socket, allowing for easier use of networking modules, Ethernet ENC28 and WiFi RS21 modules. There is still one free user socket. Other sockets can be added using the $1 Breakout Module.
CE, FCC qualification testing[/ul]
