About the Picon one hw PCB

Picon one hw is an open source AVR/Arduino PCB design by fm4dd, published on GitHub under the CERN-OHL-1.2 license. It is a 2-layer board measuring 117.8 × 168 mm, with 59 components from 31 distinct parts.

Its main chip is the ARDUINO_MKRGPS_MOD, from the AVR/Arduino family. Other key parts include the TI_DCR021205, TM1640, DS3231M and SC16IS752_I2C2UARTx2_IC. By type, the board carries 23 resistors, 10 capacitors, 4 ICs, 4 modules, 4 switches and 4 diodes.

From the project

KiCad PCB, gerber, and CAD files for the PiCon-One controller.

PiCon-One is a multi-function controller for automation and industrial use cases. At its heart is the smallest member of the Raspberry family, the Raspberry Pi Zero W. Instead of adding a "hat" on top of the Raspberry, I reversed the roles: The Pi becomes the "hat" for the controller mainboard, which has been fitted to a Takachi enclosure.

The design aims to add flexible power configuration, real-time clock, GPS positioning, display and communication interfaces, enabling rapid prototyping under the widespread Raspberry Pi ecosystem.

The KiCad project lives in the fm4dd/picon-one-hw repository on GitHub; these links point at the commit this page was built from.

Picon one hw: common questions

What microcontroller does the Picon one hw use?

The Picon one hw is built around the ARDUINO_MKRGPS_MOD, from the AVR/Arduino family.

How big is the Picon one hw PCB?

The Picon one hw measures 117.8 × 168 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Picon one hw?

59 components, from 31 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.

Where can I download the Picon one hw design files?

From the fm4dd/picon-one-hw repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Picon one hw design in my own project?

Yes, under the terms of its CERN-OHL-1.2 license, which fm4dd chose for the repository.

Can I test firmware for the Picon one hw without the hardware?

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