P12800HY101X_B01

P12800HY101X_B01 is an industrial level Android LCM based on Rockchip RK PX30 ARM. It is equipped with Quad-core Coretex-A35, supporting most decoding solutions under 1080p@60fps, H.265/H.264/MVC/VP8 solutions and many other great features of Rockchip RK PX30. Meanwhile, with good jpeg picture processing performance and 3D GPU, it supports OpenGL ES2.0 and OpenVG1.1.

Rockchip RK PX30 has high-performance external memory interface (DDR3/DDR3L/LPDDR2) capable of sustaining demanding memory bandwidths, also provides a complete set of peripheral interface to support very flexible applications.

Note: The serial port voltage supports 5V and 12V, with 5V being the default setting. You can control the voltage by following the instructions on the next page. It is a difficult task to modify the serial port voltage and RS485 to TTL, which may cause damage to the product. If you need to modify the product, please inform us before purchasing, and we will entrust the factory to modify it.

Change serial port voltage from 12V to 5V

Operation: Move the 0Ω resistor from the backside R235 to the frontside R233 (next to the label ‘5V’)

Change the 485 setting of Serial Port 4 to TTL.

As shown in the figure below: 1. Remove the frontside D23. 2. Move the backside resistors R224 and R225 to the positions of R222 and R223, respectively.
