About the OMOTE PCB

OMOTE is an open source RP2040/RP2350 PCB design by Porshe2010, published on GitHub under the GPL-3.0 license. It is a 2-layer board measuring 192.4 × 50 mm, with 105 components from 35 distinct parts.

Its main chip is the ESP32-PICO-D4, from the RP2040/RP2350 family. Other key parts include the MCP73831-2-OT, XC6220B331, CH340C, USBLC6-2P6 and LIS3DHTR. By type, the board carries 31 resistors, 25 switches, 25 capacitors, 8 ICs, 5 transistors and 5 diodes.

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

From the project

OMOTE is an ESP32 based open source universal remote. Its capacitive 2.8” touchscreen provides an intuitive and snappy user interface for switching devices and settings. No hub or docking station is required as the remote features infrared, Wi-Fi and Bluetooth connectivity. With its well optimized power consumption, OMOTE can run for months on a charge. And since the design files are open source, you can fully customize them to your devices and needs.

OMOTE: common questions

What microcontroller does the OMOTE use?

The OMOTE is built around the ESP32-PICO-D4, from the RP2040/RP2350 family.

How big is the OMOTE PCB?

The OMOTE measures 192.4 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the OMOTE?

105 components, from 35 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 OMOTE design files?

From the Porshe2010/OMOTE 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 OMOTE design in my own project?

Yes, under the terms of its GPL-3.0 license, which Porshe2010 chose for the repository.

Can I test firmware for the OMOTE without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug RP2040/RP2350 firmware against it before you order a PCB.
