About the Roomba esp wifi PCB

Roomba esp wifi is an open source ESP8266 PCB design by kg333, published on GitHub under the CC-BY-SA-4.0 license. It is a 2-layer board measuring 25.4 × 30.5 mm, with 14 components from 7 distinct parts.

Its main chip is the ESP-12F, from the ESP8266 family. Other key parts include the TSR_1-2433. By type, the board carries 9 resistors, 2 ICs, 2 capacitors and 1 connector.

It belongs with the iot & wireless designs in this gallery.

From the project

Board for adding wifi using ESP-12 to Roomba 500/600 series

This project describes a board with an ESP-12 microcontroller and the following interfaces: UART - 3.3V, 5.0V tolerant Battery input - supports 4.75V - 36V GPIO - single pin at 3.3V 3.3V auxiliary output

It is intended for use with esp-roomba-mqtt by John Boiles, but may also be suitable for general use in battery-powered applications.

This board can be intially programmed in a similar fashion to a NodeMCU using your preferred Arduino programmer, but does require manual control using the PRGM and RST buttons. If using esp-roomba-mqtt, it may be programmed over Wifi after the initial flash.

Roomba esp wifi: common questions

What microcontroller does the Roomba esp wifi use?

The Roomba esp wifi is built around the ESP-12F, from the ESP8266 family.

How big is the Roomba esp wifi PCB?

The Roomba esp wifi measures 25.4 × 30.5 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Roomba esp wifi?

14 components, from 7 distinct parts. The full bill of materials is listed on this page.

Where can I download the Roomba esp wifi design files?

From the kg333/roomba_esp_wifi repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Roomba esp wifi design in my own project?

Yes, under the terms of its CC-BY-SA-4.0 license, which kg333 chose for the repository.

Can I test firmware for the Roomba esp wifi without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP8266 firmware against it before you order a PCB.
