About the Embedduino PCB

Embedduino is an open source AVR/Arduino PCB design by MAHESH-THILAK-K, published on GitHub under the Apache-2.0 license. It is a 2-layer board measuring 67.5 × 82.7 mm, with 46 components from 35 distinct parts.

Its main chip is the ATMEGA328P-AU, from the AVR/Arduino family. Other key parts include the TLV76750DRVx, AMS1117-3.3, APDS-9960 and HC-05. By type, the board carries 15 resistors, 13 capacitors, 5 ICs, 5 connectors, 3 diodes and 2 LEDs.

It belongs with the iot & wireless, dev boards & breakouts and usb & debug tools designs in this gallery.

From the project

Embedduino is a custom-designed development board based on the ATmega328P-AU, integrating power regulation, communication interfaces, and onboard peripherals into a compact PCB.

Embedduino is a custom-designed development board based on the ATmega328P-AU, integrating power regulation, communication interfaces, and onboard peripherals into a compact PCB.

It is built to bridge the gap between Arduino prototyping and real hardware design.

Embedduino: common questions

What microcontroller does the Embedduino use?

The Embedduino is built around the ATMEGA328P-AU, from the AVR/Arduino family.

How big is the Embedduino PCB?

The Embedduino measures 67.5 × 82.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Embedduino?

46 components, from 35 distinct parts. The full bill of materials is listed on this page.

Where can I download the Embedduino design files?

From the MAHESH-THILAK-K/ADDITIONAL-PROJECT repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Embedduino design in my own project?

Yes, under the terms of its Apache-2.0 license, which MAHESH-THILAK-K chose for the repository.

Can I test firmware for the Embedduino 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.
