About the UDS-logger PCB

UDS-logger is an open source AVR/Arduino PCB design by rkhvrnen, published on GitHub under the MIT license. It is a 2-layer board measuring 120 × 60 mm, with 82 components from 33 distinct parts.

Its main chip is the 328P-MUR, from the AVR/Arduino family. Other key parts include the LM1117IMPX-5.0, FT232RL, MCP2515-xSO and MCP2551-I-SN. By type, the board carries 30 resistors, 12 diodes, 10 connectors, 10 capacitors, 9 ICs and 4 crystals.

UDS-logger: common questions

What microcontroller does the UDS-logger use?

The UDS-logger is built around the 328P-MUR, from the AVR/Arduino family.

How big is the UDS-logger PCB?

The UDS-logger measures 120 × 60 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UDS-logger?

82 components, from 33 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 UDS-logger design files?

From the rkhvrnen/UDS-logger 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 UDS-logger design in my own project?

Yes, under the terms of its MIT license, which rkhvrnen chose for the repository.

Can I test firmware for the UDS-logger without the hardware?

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