## Introduction

Both CEx7 LX2160 and CEx7 CN9132 are designed as COM Expresses Type 7 standard, therefore their carriers such as HoneyComb and CN9132 EVAL, can support either of the COMs. The COM Express type 7 standard is not strict and allows a certain amount of flexibility, therefore, even though both CEx7 LX2160 and CEx7 CN9132 are COM Expresses Type 7, the features and pinout are slightly different. Below, is a detailed explanation on the difference and the usage of CEx7 CN9132 on the HoneyComb CEx7 LX2160 carrier
