About the Development board

Development board is an open source PCB design by inoa-io, published on GitHub under the CERN-OHL-P-2.0 license. It is a 2-layer board measuring 153 × 77 mm, with 97 components from 52 distinct parts.

Other key parts include the LD1117S33, FT2232HL, 93C46-WMN6TP, LTV-817S and MAX3486. By type, the board carries 40 resistors, 17 capacitors, 11 diodes, 10 connectors, 8 ICs and 4 transistors.

It belongs with the rf & radio and dev boards & breakouts designs in this gallery.

From the project

Satellite Hardware Project and Documentation

The Inoa Satellite is a lightweight and secure gateway for your fuse box or industrial environment.

Please see our Project Pages for details.

There is a huge amount of IoT gateways out there, but none of these fulfill completely all of our design goals:

Usage in a rough industrial environment Hardware driven security (HSM) Inexpensive hardware to be able to finance a huge fleet of devices Low energy consumption Fuse box casing (DIN rail) Small (2 FE / 36 mm) to allow mounting in existing fuse boxes Extendable design to be future proof Modular design to adapt hardware to use cases and keep…
