Firmware Support (Micropython)
- Use the insighioNode repository for a plug-and-play solution.
- Use the astronode-micropython library for custom scenarios.
Notes
The ASTROCAST Satellite IoT shield can be directly used with any other ESP32 module or dev board and our Micropython firmware.
Custom designs
The existing boards are highly configurable and expandable so if the existing boards do not fit your need, get in contact with us and we will tailor a solution for you with your customizations.
