About the ARGOS DEMO PCB

ARGOS DEMO is an open source PCB design by CNES, published on GitHub under the CERN-OHL-S-2.0 license. It is a 4-layer board measuring 50 × 80 mm, with 85 components from 42 distinct parts.

Other key parts include the LTC4365DDB, TPS63900, 82400102 and FT231XQ. By type, the board carries 34 resistors, 16 capacitors, 9 diodes, 8 connectors, 6 inductors and 5 ICs.

It belongs with the usb & debug tools, iot & wireless and rf & radio designs in this gallery.

From the project

Demo board designed to use the ARRIBADA SMD module via USB to send ARGOS messages to the Kineis constellation.

Demonstration and evaluation board designed to operate the Arribada Argos SMD module via USB and transmit ARGOS uplink messages to the Kineis satellite constellation.

This project presents an Argos Transceiver Demonstration Board intended for the evaluation, validation, and operation of the Arribada Argos SMD module. The board provides a compact and robust hardware platform to transmit ARGOS uplink messages to the Kineis satellite constellation using a standard USB interface.
