About the GateDr mainboard PCB

GateDr mainboard is an open source Microchip SAM PCB design by PajamaLlamaLand, published on GitHub. It is a 4-layer board measuring 47 × 106 mm, with 111 components from 30 distinct parts.

Its main chip is the ATSAMD21E17A-AU, from the Microchip SAM family. Other key parts include the LM1117MP-3.3, LM4040BIM3X-10, MCP6004-I/SL, MCP6002-I/SN and TL074HIDR. By type, the board carries 39 resistors, 36 capacitors, 14 connectors, 8 diodes, 7 ICs and 4 switches.

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

From the project

The Gate Doctor is a multi-functional logic, comparator, and gate manipulation module in the Eurorack synth format.

The Gate Doctor is a multi-functional logic, comparator, and gate manipulation module in the Eurorack synth format.

The module is based around extracting, combining, and further modulating gate signals from your Eurorack system. It can be a simple comparator, logic module, clock divider, probability generator, gate delay (plus plenty of other features/modulation options), or many combinations of those at once!

GateDr mainboard: common questions

What microcontroller does the GateDr mainboard use?

The GateDr mainboard is built around the ATSAMD21E17A-AU, from the Microchip SAM family.

How big is the GateDr mainboard PCB?

The GateDr mainboard measures 47 × 106 mm, has 4 copper layers and is 1.2 mm thick.

How many components are on the GateDr mainboard?

111 components, from 30 distinct parts. The full bill of materials is listed on this page.

Where can I download the GateDr mainboard design files?

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

Can I use the GateDr mainboard design in my own project?

The repository has no license, so all rights stay with PajamaLlamaLand. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the GateDr mainboard 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.
