PCN-20190502-PICO-IMX7

This letter serves as a formal product change notification (PCN) for TechNexion Parts PICO-IMX7 Family.

This PCN involves changes to wireless functionality and storage options. There is also a part number change to differentiate new products from discontinued products.

Reason for the Change 

In the past several years the ubiquitous popularity of the Internet of Things (IoT) has caused a major shift within our customer base towards configurations that feature more advanced and scalable Wi-Fi and Bluetooth functionalities.

The new PICO-IMX7 Family answers this need by providing a new wireless solution that offers:

1. Concurrent Wi-Fi (AP and client mode). This is mostly used for initial configuration and device
2. Bluetooth 5
3. System on Modules with Wi-Fi capabilities that offer -40~85C operating temperature
4. Regulatory Certification:
   1. North America : TechNexion Wi-Fi module carry FCC ID : 2AKZA-QCA9377
   2. Canada : TechNexion Wi-Fi module carry IC ID : 22364-QCA9377
   3. Japan : TechNexion Wi-Fi module carry TELEC ID : 201-180629
   4. EU : *(note)
   5. Australia / New Zealand : *(note)

Note : For EU and Australia/New Zealand general module certification has been carried out for ETSI, CE, RED compliance and reports can be requested by email to submit to the customer’s local test lab. Complete system certification is still required and TechNexion has a staff of qualified EMC/EMI/RF test engineers available to assist customers with additional certification requests.
