Remram: common questions

What microcontroller does the Remram use?

The Remram is built around the STM32F765VIT6, from the STM32 family.

How big is the Remram PCB?

The Remram measures 140 × 104 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Remram?

259 components, from 59 distinct parts. The full bill of materials is listed on this page.

Where can I download the Remram design files?

From the hasenbanck/remram repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Remram design in my own project?

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

Can I test firmware for the Remram without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
