About the Iot PCB

Iot is an open source Raspberry Pi PCB design by dotnet, published on GitHub under the MIT license. It is a 2-layer board measuring 56 × 65 mm, with 24 components from 12 distinct parts.

Its main chip is the Raspberry_Pi_2_3, from the Raspberry Pi family. By type, the board carries 14 resistors, 6 transistors, 2 connectors, 1 diode and 1 capacitor.

It belongs with the displays & leds and iot & wireless designs in this gallery.

From the project

This repo includes .NET Core implementations for various IoT boards, chips, displays and PCBs.

Seatalk, also called Seatalk1, is a bus protocol used by the marine equipment company Raymarine. It is used as a protocol to connect various devices on a boat, such as depth sounders, anemometers (wind sensors), autopilots and displays. The protocol is the successor of NMEA-0183, providing the main benefit of being able to connect various devices to a single bus, without the need of complex star networks and bridges as it was required for NMEA-0183.

Iot: common questions

What microcontroller does the Iot use?

The Iot is built around the Raspberry_Pi_2_3, from the Raspberry Pi family.

How big is the Iot PCB?

The Iot measures 56 × 65 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Iot?

24 components, from 12 distinct parts. The full bill of materials is listed on this page.

Where can I download the Iot design files?

From the dotnet/iot repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Iot design in my own project?

Yes, under the terms of its MIT license, which dotnet chose for the repository.

Can I test firmware for the Iot without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Raspberry Pi firmware against it before you order a PCB.
