- Power-Only USB Type-C Receptacle - 3.3V LDO Voltage Regulator - Red Power On LED Indicator - UPDI Interface

Programmable using SerialUPDI (recommended) or jtag2updi.

Install avrdude following these instructions on their GitHub. Don't install through your system's package manager, or you'll get an older version of avrdude that doesn't have SerialUPDI.

Attiny202-dev board: common questions

What microcontroller does the Attiny202-dev board use?

The Attiny202-dev board is built around the C616039, from the AVR/Arduino family.

How big is the Attiny202-dev board?

The Attiny202-dev board measures 24 × 33.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Attiny202-dev board?

13 components, from 11 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 Attiny202-dev board design files?

From the AnOrdinaryUsername/attiny202-dev-board 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 Attiny202-dev board design in my own project?

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

Can I test firmware for the Attiny202-dev board 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.
