The old AR3207G-D uses a black PCB board, and the silk screen is AR3207G. The new AR3207G-D uses a purple PCB board, and the silk screen is Ma-RX62HE-D. This is because the new AR3207G-D and the new Ma-RX62HE -D shares a set of PCB boards. The hardware difference is that AR3207G-D has one more gyroscope chip and some resistors and capacitors than Ma-RX62HE-D.
