About the Single radio PCB

Single radio is an open source ESP8266 PCB design by AnyLeaf, published on GitHub under the MIT license. It is a 4-layer board measuring 37.7 × 37.7 mm, with 43 components from 27 distinct parts.

Its main chip is the ESP8285, from the ESP8266 family. Other key parts include the C587158, SX1281, 2450FM07D0034T and SE2431L. By type, the board carries 20 capacitors, 9 resistors, 5 ICs, 3 connectors, 3 inductors and 2 crystals.

It belongs with the rf & radio designs in this gallery.

From the project

This repo contains open source hardware information for AnyLeaf ELRS receivers

This repo contains published hardware information for the AnyLeaf ELRS receivers. It contains schematics, KiCad schematic and PCB layout files, and production files (Gerbers, drill files, bill of materials (BOM), and pick+place files). If you have any questions or concerns, please post a Github issue here, or contact us at anyleaf@anyleaf.org.

Images of the schematics are provided as PNG files in the main repo; this is the easiest way to view the schematics.

Single radio: common questions

What microcontroller does the Single radio use?

The Single radio is built around the ESP8285, from the ESP8266 family.

How big is the Single radio PCB?

The Single radio measures 37.7 × 37.7 mm, has 4 copper layers and is 4.69 mm thick.

How many components are on the Single radio?

43 components, from 27 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 Single radio design files?

From the AnyLeaf/elrs-hardware repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the Single radio design in my own project?

Yes, under the terms of its MIT license, which AnyLeaf chose for the repository.

Can I test firmware for the Single radio 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.
