From: Baocheng Su <baocheng.su@xxxxxxxxxxx> Main differences between the new variant and Advanced PG2: 1. Arduino interface is removed. Instead, an new ASIC is added for communicating with PLC 1200 signal modules. 2. USB 3.0 type A connector is removed, only USB 2.0 type A connector is available. 3. DP interface is removed. Instead, to communicate with PLC 1200 signal modules, a USB 3.0 type B connector is added but the signals are actually not USB. 4. DDR size is increased to 4 GB. 5. Two sensors are added, one tilt sensor and one light sensor. The light sensor it not yet added to the DT at this stage as it depends on to-be-added bindings.
