New batch<after 2012-03> change the internal buffer, improve the driving circuit capacity. and improve the internal RC filter, because some OSD input very low impedance,like eagletree OSD PRO less 5Kohm. and some OSD input not include filter (HW filter or digital filter), so it will make the rssi unstabitily.

v1.24 add new feature link quality indicator / rf rssi indicator selectable. (rssi pin)

1. output some info over the uart port, just like link status, rssi ect.
if you need more info about uart protocol ,just email to us.
