BLE environmental sensor: common questions
What microcontroller does the BLE environmental sensor use?
The BLE environmental sensor is built around the BGM220PC22HNA2, from the Silicon Labs family.
How big is the BLE environmental sensor PCB?
The BLE environmental sensor measures 54.5 × 28 mm, has 2 copper layers and is 1 mm thick.
How many components are on the BLE environmental sensor?
24 components, from 16 distinct parts. The full bill of materials is listed on this page.
Where can I download the BLE environmental sensor design files?
From the atuleu/aristeus repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the BLE environmental sensor design in my own project?
Yes, under the terms of its CERN-OHL-S-2.0 license, which atuleu chose for the repository.
Can I test firmware for the BLE environmental sensor without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Silicon Labs firmware against it before you order a PCB.
