ProgrammableRelayModule2Channel: common questions
What microcontroller does the ProgrammableRelayModule2Channel use?
The ProgrammableRelayModule2Channel is built around the ATMEGA328-NEW, from the AVR/Arduino family.
How big is the ProgrammableRelayModule2Channel PCB?
The ProgrammableRelayModule2Channel measures 100 × 60 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the ProgrammableRelayModule2Channel?
64 components, from 38 distinct parts. The full bill of materials is listed on this page.
Where can I download the ProgrammableRelayModule2Channel design files?
From the numato/samplecode repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the ProgrammableRelayModule2Channel design in my own project?
The repository has no license, so all rights stay with numato. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the ProgrammableRelayModule2Channel 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.
