1. Introduction

The Agora wireless platform is a multi-sensor modem assembly with integrated MCU designed to be used as a

versatile solution for the rapid integration of Cellular, Bluetooth, and/or LoRa connectivity to all kinds of new or

existing product designs. It is capable of hosting a variety of environmental sensors and communicating sensor data

wirelessly over 2.4GHz Bluetooth, 868/915MHz LoRa or 4G LTE Cat1 depending on configuration. Leveraging Agora

helps cut design time, complexity, and R&D effort, getting end-user products to market faster. Sensor options can

accommodate the monitoring of temperature, relative humidity, barometric pressure, VOC gas, air quality, audio,

distance (Time of Flight / ToF), and inertial forces (accelerometer/gyroscope/magnetometer). Agora can be available

as a PCBA (printed circuit board assembly) or as a full module which includes a custom-designed plastic enclosure,

LiPo battery, and LiPo charging circuit with a micro-USB input. The Agora board itself can be integrated into your

own system using either a standard twin 10-pin header modem footprint or its specialized Tectonic Edge™ board-

edge connector. Choose whether to power it from a dedicated LiPo battery, ac/dc wall-wart, or your own hardware.

Certifications include PTCRB, Verizon, AT&T TRENDI, and ARM MBED Enabled.
