About the Astra board
Astra board is an open source ESP32 PCB design by verIdyia, published on GitHub. It is a 2-layer board measuring 60 × 40 mm, with 53 components from 22 distinct parts.
Its main chip is the ESP32-C3-WROOM-02-N4, from the ESP32 family. Other key parts include the AMS1117-3.3, SN74AHCT1G125DBVR and USBLC6-2SC6. By type, the board carries 16 capacitors, 15 resistors, 8 diodes, 4 ICs, 4 connectors and 4 switches.
It belongs with the dev boards & breakouts designs in this gallery.
From the project
ESP32-C3 development board: a documented AI-assisted PCB experiment
ESP32-C3 development board built as a documented AI-assisted PCB experiment.
Manufacturing paused due to cost (2026-09-10). The owner reported approximately US$123 for Standard PCBA and US$85 for Economic PCBA in the 10-board quote discussion, and chose to stop procurement. These are owner-reported figures, not an independently verified complete checkout total; shipping/tax inclusion and complete LED assembly are unconfirmed. No order or payment was submitted.

Astra board: common questions
What microcontroller does the Astra board use?
The Astra board is built around the ESP32-C3-WROOM-02-N4, from the ESP32 family.
How big is the Astra board?
The Astra board measures 60 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Astra board?
53 components, from 22 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 Astra board design files?
From the verIdyia/astra-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 Astra board design in my own project?
The repository has no license, so all rights stay with verIdyia. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Astra board 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.
