OSBAMS Rev2 RC1: common questions
What microcontroller does the OSBAMS Rev2 RC1 use?
The OSBAMS Rev2 RC1 is built around the STM32L476RGT6, from the STM32 family.
How big is the OSBAMS Rev2 RC1 PCB?
The OSBAMS Rev2 RC1 measures 100 × 90 mm, has 4 copper layers and is 1.6 mm thick.
How many components are on the OSBAMS Rev2 RC1?
115 components, from 63 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 OSBAMS Rev2 RC1 design files?
From the hle12345/OSBAMS 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 OSBAMS Rev2 RC1 design in my own project?
Yes, under the terms of its MIT license, which hle12345 chose for the repository.
Can I test firmware for the OSBAMS Rev2 RC1 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.
