Hi @manasa.chinnam,

Welcome to our community!

Please refer to the HL78xx - Development Kit User Guide at the following link to see if it helps:

Thanks,

That may not be the correct user manual. That is for this product, which is unavailable:

> **[HL78 DEV KIT\_6001210 | DigiKey Electronics](https://www.digikey.com/en/products/detail/sierra-wireless/HL78-DEV-KIT-6001210/10136430)**
>
> Order today, ships today. HL78 DEV KIT\_6001210 – HL - AirPrime® HL Cellular Development Platform Evaluation Board from Sierra Wireless. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

It’s possible that the enquiry is for a manual for this product (which, though marked on the package as a Sierra Wireless product, I’m unable to find on the wesite):

> **[HL7812-DEVKIT | DigiKey Electronics](https://www.digikey.com/en/products/detail/sierra-wireless/HL7812-DEVKIT/22248699)**
>
> Order today, ships today. HL7812-DEVKIT – HL - AirPrime® HL7812 Cellular Development Platform Evaluation Board from Sierra Wireless. Pricing and Availability on millions of electronic components from Digi-Key Electronics.

I, for one, would like directions to the documentation for the second product.

Thank you in advance!

That does in fact appear to be the correct board, even if the processor is from a different family. Thank you! You might want to provide that link on the HL7812 page at [AirPrime - HL78xx - Development Kit User Guide](https://source.sierrawireless.com/resources/airprime/development_kits/airprime_hl78xx_development_kit_user_guide/#sthash.CpcK27cM.dpbs)
