Welcome to the future of open source Argos / Kinéis development
Arribada Argos SMD Module

Small, versatile and Kineis pre-certified*
The Arribada Argos SMD module is a compact, high-performance PCB designed to facilitate satellite uplink communication for a wide range of applications.
With its small footprint and versatile integration options, this module can stand alone or be a co-processor for designs requiring satellite connectivity.
Built on the STM32WL55 processor and equipped with the GR5504 power amplifier, the module delivers up to 26 dBm transmission power and is pre-certified* by CLS, ensuring immediate deployment readiness.

Key Features
- Compact Design: Castellated edges for easy integration into new or existing designs.
- High efficiency: Built on the STM32WL55 with a GR5504 amplifier for reliable satellite uplink and low power consumption.
- Integration Options: Feather breakout board available for seamless testing and integration; only power and an antenna are necessary.
- Flexibility: Can be used as a standalone solution or an RF module.
- Kineis Compatibility: Fully compatible with KINEIS stack and KINEIS GUI; certified by Kineis/CNES for all modulation (LDA2, VLDA4, LDK)


*The Arribada Argos SMD module is Kinéis pre-certified and integrators will need to send their IQ records utilising EMULSAT Kinéis software (for ADALM PLUTO) to CLS for validating the correct powering of the PA.

Stackable & Modular
Add an SMD Wing to seamlessly connect Feather boards such as the Adafruit Feather series to the Argos SMD module for streamlined testing and integration.
SMD Module


- Compact Design: 20x20x2mm with castellated edges for easy integration.
