Due to the different monitor and light effect, the actual color of the item might be slightly different from the color showed on the pictures. Thank you!
Please allow 1-2cm measuring deviation due to manual measurement.

NOTE:
1.For DIY—The outer casing is a material package, It needs to be assembled by itself, and the material package is given a screwdriver.

2.—Attention!The heat sink tape 3M glue needs to be pasted to the chip by itself. Please refer to the picture in the description. The hotter the more sticky the thermal conductivity is.The shell version needs to be assembled by yourself. Screwdriver is given with the shell version.

3.For use—The power switch on the board is standby switch. After the switch is off, the machine is in standby state with low power consumption. If the power is completely turned off or the DC plug on the machine can be unplugged for a long time.
