Ble soil moisture sensor pannel: common questions

What microcontroller does the Ble soil moisture sensor pannel use?

The Ble soil moisture sensor pannel is built around the BGM111, from the Silicon Labs family.

How big is the Ble soil moisture sensor pannel PCB?

The Ble soil moisture sensor pannel measures 170 × 36 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ble soil moisture sensor pannel?

29 components, from 14 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ble soil moisture sensor pannel design files?

From the Miceuz/ble-soil-moisture-sensor repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Ble soil moisture sensor pannel design in my own project?

Yes, under the terms of its Apache-2.0 license, which Miceuz chose for the repository.

Can I test firmware for the Ble soil moisture sensor pannel 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.
