About the Antdroid board

Antdroid board is an open source AVR/Arduino PCB design by antdroid-hexapod, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 99.5 × 53.7 mm, with 58 components from 22 distinct parts.

Its main chip is the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family. Other key parts include the LM2678T-5.0 and LM2675M-5. By type, the board carries 21 jumpers, 13 capacitors, 8 resistors, 5 diodes, 3 ICs and 3 inductors.

It belongs with the power & battery, dev boards & breakouts and robotics & motion designs in this gallery.

From the project

Antdroid board is a shield for Arduino Mega thinked for Antdroid Hexapod

This is an alternative to the use of the SBEC, USB converter, LiPo alarm and Arduino Mega Shield protoboard for the robot Antdroid. ## Board features Two power supply of 5V 5A for servos. 19 servos pinheader connection Pin to control servos power supply One power suply of 5V 2A for Raspberry Pi Logic level converter to allow serial pin connection between Arduino and Raspberry Pi Analog input to measure battery voltage * Optional I2C connection

Antdroid board: common questions

What microcontroller does the Antdroid board use?

The Antdroid board is built around the ARDUINO_MEGA_SHIELD, from the AVR/Arduino family.

How big is the Antdroid board?

The Antdroid board measures 99.5 × 53.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Antdroid board?

58 components, from 22 distinct parts. The full bill of materials is listed on this page.

Where can I download the Antdroid board design files?

From the antdroid-hexapod/antdroid-board repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Antdroid board design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which antdroid-hexapod chose for the repository.

Can I test firmware for the Antdroid 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.
