1. Introduction

Atlas is a modem development board that assist in programming, debugging, and testing embedded cell modem

products from Embedded Planet. An nRF52840 MCU acts as the host processor that can manage the attached

cellular modem and act as a programming/debugging interface. This MCU module also includes a Bluetooth function

that is leveraged on this product using an onboard chip antenna. Additional onboard prototyping features include an

onboard resistive temperature sensor, GPIO-connected pushbutton input, GPIO-controlled RGB LED,

programming/debugging USB-micro connector, cell module passthrough USB-micro connector, power selection

header, Cortex debug header, and more. The Tectonic Edge™ connector on the Atlas board itself allows it to be

programmed by Flidor or integrated with other EP development tools & adapters. The Atlas board can also be

programmed/accessed using the Cortex debug/programming header.

Power your modem devices

Designed with the Chronos embedded cellular modem by Embedded Planet in mind, the Atlas board features a

2×10 modem header for seamless connection to Chronos. Atlas is also capable of operating with the 2x10 modem

header configuration of the Agora module.

Agora is an IoT solution platform that incorporates the processing power of an onboard MCU with the wireless

connectivity of cellular, Bluetooth, & LoRa while collecting sensor data. Onboard sensors can include 6-axis IMU, 9-

axis IMU, Time-of-Flight (ToF) distance, temperature/humidity, temperature/humidity/pressure/VOC gas, and

sound/microphone. The cellular module is available in configurations that include GNSS capabilities. Some

configurations of Agora include custom plastics & a LiPo battery with recharging capabilities. Agora can operate as

a standalone module or be integrated into new or existing hardware designs. To learn more about Agora & how to

leverage its capabilities, visit https://www.embeddedplanet.com/agora.
