About the UPDI programmer PCB

UPDI programmer is an open source AVR/Arduino PCB design by dbuchwald, published on GitHub under the MIT license. It is a 2-layer board measuring 67.3 × 25.4 mm, with 29 components from 19 distinct parts.

Its main chip is the ATmega168P-20AU, from the AVR/Arduino family. Other key parts include the FT230XS. By type, the board carries 11 capacitors, 7 resistors, 3 connectors, 3 diodes, 2 ICs and 1 crystal.

It belongs with the usb & debug tools designs in this gallery.

UPDI programmer: common questions

What microcontroller does the UPDI programmer use?

The UPDI programmer is built around the ATmega168P-20AU, from the AVR/Arduino family.

How big is the UPDI programmer PCB?

The UPDI programmer measures 67.3 × 25.4 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UPDI programmer?

29 components, from 19 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 UPDI programmer design files?

From the dbuchwald/kicad-simple repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the UPDI programmer design in my own project?

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

Can I test firmware for the UPDI programmer 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.
