2 Overview
The COMO-N832C is a short-range, Class 2, BLE single mode module for implementing Bluetooth functionality into
various electronic devices.
And cost-effective, low-power, true system-on-chip (SoC) for Bluetooth low energy applications. It enables robust BLE
master or slave nodes to be built with very low total bill-of-material costs.
