About the Tbogg-Sensor-Package PCB

Tbogg-Sensor-Package is an open source ESP32 PCB design by UofC-GNCTR-2024, published on GitHub under the MIT license. It is a 2-layer board measuring 52 × 67 mm, with 40 components from 23 distinct parts.

Its main chip is the ESP32-Module-30Pin, from the ESP32 family. Other key parts include the LoRa-E5, GY-NEO6MV2-Module, STDS75DS2F, AD8226ARZ and MCP6002-xP. By type, the board carries 13 resistors, 12 connectors, 8 capacitors, 6 ICs and 1 switch.

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

From the project

The sensor package (strain, temperature, vibration) for the 2024 UofC GNCTR tbogg. Designed as an R&D intrastructure monitoring solution.

Tbogg-Sensor-Package: common questions

What microcontroller does the Tbogg-Sensor-Package use?

The Tbogg-Sensor-Package is built around the ESP32-Module-30Pin, from the ESP32 family.

How big is the Tbogg-Sensor-Package PCB?

The Tbogg-Sensor-Package measures 52 × 67 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Tbogg-Sensor-Package?

40 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Tbogg-Sensor-Package design files?

From the UofC-GNCTR-2024/Tbogg-Sensor-Package-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 Tbogg-Sensor-Package design in my own project?

Yes, under the terms of its MIT license, which UofC-GNCTR-2024 chose for the repository.

Can I test firmware for the Tbogg-Sensor-Package without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
