Things to note

ESD Precaution​

Please note that the iMX RT uCOM Board and uCOM Carrier Board come without any case/box and all components are exposed for finger touches – and therefore extra attention must be paid to ESD (electrostatic discharge) precaution.

Make it a habit always to first touch the metal surface of one of the USB, uSD or Ethernet connectors for a few seconds with both hands before touching any other parts of the boards. That way, you will have the same potential as the board and therefore minimize the risk for ESD. Never touch directly on the iMX RT uCOM Board and in general as little as possible on the uCOM Carrier Board. The push-buttons on the uCOM Carrier Board have grounded shields to minimize the effect of ESD.

warning

Note that Embedded Artists does not replace boards that have been damaged by ESD.

General Handling Care​

Handle the iMX RT uCOM Board and uCOM Carrier Board with care. The boards are not mounted in a protective case/box and are not designed for rough physical handling. Connectors can wear out after excessive use. The uCOM Carrier Board is designed for prototyping use, and not for integration into an end-product.

For boards with LCD, do not exercise excessive pressure on the LCD glass area. That will damage the display. Also, do not apply pressure on the flex cables connecting the LCD/touch screen. These are relatively sensitive and can be damaged if too much pressure is applied to them.

warning

Note that Embedded Artists does not replace boards where the LCD has been improperly handled.

OTP Fuse Programming​

The i.MX RT MCU has on-chip OTP fuses that can be programmed. Once programmed, there is no possibility to reprogram them.

iMX RT uCOM Boards are delivered with OTP fuse programming to boot from external QSPI flash. The rest of the fuses are completely up to the user to decide if OTP fuses shall be programmed and in that case, which ones.

warning

Note that Embedded Artists does not replace iMX RT uCOM Boards because of wrong OTP programming. It’s the user’s responsibility to be absolutely certain before OTP programming and not to program the fuses by accident.
