About the Bluetooth and-Mioty-Localization-Hardware PCB

Bluetooth and-Mioty-Localization-Hardware is an open source STM32 PCB design by Chandubreddy819, published on GitHub. It is a 4-layer board measuring 36 × 36 mm, with 58 components from 38 distinct parts.

Its main chip is the STM32F103CBUx, from the STM32 family. Other key parts include the IIS2MDCTR, CR2032, SX1280IMLTRT and ICM-45686. By type, the board carries 32 capacitors, 8 resistors, 5 ICs, 3 connectors, 3 inductors and 2 crystals.

It belongs with the iot & wireless, rf & radio and power & battery designs in this gallery.

From the project

A coin-cell-powered asset-tracking module that shares a single 2.4 GHz radio (Semtech SX1280) between two protocols: frequent BLE/Google FMDN advertisements for precise short-range tracking, and periodic mioty (TS-UNB) uplinks for long-range fallback everywhere a BLE receiver isn

A coin-cell-powered asset-tracking module that shares a single 2.4 GHz radio (Semtech SX1280) between two protocols: frequent BLE/Google FMDN advertisements for precise short-range tracking, and periodic mioty (TS-UNB) uplinks for long-range fallback everywhere a BLE receiver isn't nearby.

Bluetooth and-Mioty-Localization-Hardware design files

The KiCad project lives in the Chandubreddy819/Bluetooth-and-Mioty-Localization-Hardware repository on GitHub; these links point at the commit this page was built from.

Bluetooth and-Mioty-Localization-Hardware: common questions

What microcontroller does the Bluetooth and-Mioty-Localization-Hardware use?

The Bluetooth and-Mioty-Localization-Hardware is built around the STM32F103CBUx, from the STM32 family.

How big is the Bluetooth and-Mioty-Localization-Hardware PCB?

The Bluetooth and-Mioty-Localization-Hardware measures 36 × 36 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the Bluetooth and-Mioty-Localization-Hardware?

58 components, from 38 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bluetooth and-Mioty-Localization-Hardware design files?

From the Chandubreddy819/Bluetooth-and-Mioty-Localization-Hardware repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Bluetooth and-Mioty-Localization-Hardware design in my own project?

The repository has no license, so all rights stay with Chandubreddy819. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Bluetooth and-Mioty-Localization-Hardware 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.
