NPK Board x RFM96: common questions
What microcontroller does the NPK Board x RFM96 use?
The NPK Board x RFM96 is built around the STM32L443RCT6, from the STM32 family.
How big is the NPK Board x RFM96?
The NPK Board x RFM96 measures 57 × 95 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the NPK Board x RFM96?
96 components, from 60 distinct parts. The full bill of materials is listed on this page.
Where can I download the NPK Board x RFM96 design files?
From the collins-emasi/KiCAD-PROJECTS-PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the NPK Board x RFM96 design in my own project?
The repository has no license, so all rights stay with collins-emasi. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the NPK Board x RFM96 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.
