About the DSKY-digital indicator replica PCB

DSKY-digital indicator replica is an open source Microchip SAM PCB design by rrainey, published on GitHub under the CC-BY-SA-4.0 license. It is a 4-layer board measuring 63.5 × 105.5 mm, with 237 components from 18 distinct parts.

Its main chip is the ATSAMD21E18A-A, from the Microchip SAM family. Other key parts include the AP2204K-3.3, LP5036 and TCA9543ADR. By type, the board carries 192 diodes, 17 resistors, 15 capacitors, 9 ICs, 3 connectors and 1 switch.

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

From the project

A replica of the Apollo Guidance Computer DSKY digital display implemented with LEDs

This is a scale functional replica of the Digital Indicator panel for the Apollo Guidance Computer. It is designed to be part of a larger replica of the Display and Keyboard (DSKY) module of the AGC.

This project is composed of these component subfolders:

artwork** - artwork to be printed or silk-screened onto the glass/acrylic cover.

pcb** - KiCad 9 project for the controller PCB design.

DSKY-digital indicator replica: common questions

What microcontroller does the DSKY-digital indicator replica use?

The DSKY-digital indicator replica is built around the ATSAMD21E18A-A, from the Microchip SAM family.

How big is the DSKY-digital indicator replica PCB?

The DSKY-digital indicator replica measures 63.5 × 105.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the DSKY-digital indicator replica?

237 components, from 18 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 DSKY-digital indicator replica design files?

From the rrainey/DSKY-digital-indicator-replica repository on GitHub, which has the KiCad layout, the schematic and the BOM; the links under Design files point to each one.

Can I use the DSKY-digital indicator replica design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which rrainey chose for the repository.

Can I test firmware for the DSKY-digital indicator replica without the hardware?

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