Cautions
1. The TF card cannot be hot-swapped. Please check that the TF card is properly
inserted before turning on the power;
2. Customers are not recommended to disassemble the device, since they do not
know the internal structure and it may easily result in a breakdown of the internal
circuits; there will be no compensation for problems caused by disassembling;
3. Replace the core board according to the replacement steps (To Replace CB1
with CM4);
4. Please follow the silkscreen carefully when wiring the SPI interface to the
expansion module to prevent short circuits.
