Dual port SRAM Board: common questions
What microcontroller does the Dual port SRAM Board use?
The Dual port SRAM Board is built around the ARDUINO_NANO_EVERY_0, from the AVR/Arduino family.
How big is the Dual port SRAM Board?
The Dual port SRAM Board measures 155 × 114 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Dual port SRAM Board?
48 components, from 19 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 Dual port SRAM Board design files?
From the ja1umi/MUTIF1613Project 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 Dual port SRAM Board design in my own project?
Yes, under the terms of its MIT license, which ja1umi chose for the repository.
Can I test firmware for the Dual port SRAM Board 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.
