BackplanePCB solder: common questions

What microcontroller does the BackplanePCB solder use?

The BackplanePCB solder is built around the PIC16F15345-I_GZ-MCU_MICROCHIP_PIC16_UQFN_20_4X4, from the PIC family.

How big is the BackplanePCB solder PCB?

The BackplanePCB solder measures 470 × 59 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the BackplanePCB solder?

88 components, from 49 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 BackplanePCB solder design files?

From the jeremysiebers/Siebwalde repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the BackplanePCB solder design in my own project?

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

Can I test firmware for the BackplanePCB solder without the hardware?

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