About the Easy-Digital-Beacons v1 PCB

Easy-Digital-Beacons v1 is an open source ESP8266 PCB design by kholia, published on GitHub under the Custom license license. It is a 2-layer board measuring 97.5 × 59.3 mm, with 13 components from 10 distinct parts.

Its main chip is the WeMos_D1_mini, from the ESP8266 family. By type, the board carries 3 resistors, 1 IC, 1 switch and 1 capacitor.

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

From the project

A simple and easy Arduino / Pi Pico / ESP8266-powered WSPR, FT8, and FT4 beacon system which uses NTP + DS3231 RTC for timing. Super extensible! Now comes with optional GPS support.

A simple and easy WiFi-enabled ESP8266-powered WSPR, FT8, and FT4 beacon system which uses NTP + DS3231 RTC for timing. Also, checkout our cost-effective, and robust HF 5W PA system.

It is also a WiFi-enabled VFO, which is quite useful, and convenient for radio experimentation work.

Note: The whole project can be assembled on a breadboard (including the 250mW amplifier) in under 30 minutes - do give it a go ;)

Easy-Digital-Beacons v1: common questions

What microcontroller does the Easy-Digital-Beacons v1 use?

The Easy-Digital-Beacons v1 is built around the WeMos_D1_mini, from the ESP8266 family.

How big is the Easy-Digital-Beacons v1 PCB?

The Easy-Digital-Beacons v1 measures 97.5 × 59.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Easy-Digital-Beacons v1?

13 components, from 10 distinct parts. The full bill of materials is listed on this page.

Where can I download the Easy-Digital-Beacons v1 design files?

From the kholia/Easy-Digital-Beacons-v1 repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Easy-Digital-Beacons v1 design in my own project?

It is published under Custom license, which limits how it may be reused; read the license before building on it.

Can I test firmware for the Easy-Digital-Beacons v1 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.
