About the Raesp gateway PCB

Raesp gateway is an open source ESP8266 PCB design by cziter15, published on GitHub under the GPL-3.0 license. It is a 4-layer board measuring 47 × 33 mm, with 17 components from 13 distinct parts.

Its main chip is the ESP-12S, from the ESP8266 family. Other key parts include the Ai-Thinker-Ra-02 and AMS1117-3.3. By type, the board carries 7 capacitors, 3 ICs, 3 resistors, 2 connectors and 2 diodes.

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

From the project

:satellite: A standalone device project featuring SX1278 and ESP8266 components, serving as a radio-WiFi gateway. The primary objective is to provide support for OOK remote power outlets, with the flexibility for potential future integration of LoRa 433 and other communication protocols, thanks to its adaptable hardware.

Raesp gateway: common questions

What microcontroller does the Raesp gateway use?

The Raesp gateway is built around the ESP-12S, from the ESP8266 family.

How big is the Raesp gateway PCB?

The Raesp gateway measures 47 × 33 mm, has 4 copper layers and is 1.625 mm thick.

How many components are on the Raesp gateway?

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

Where can I download the Raesp gateway design files?

From the cziter15/raesp_gateway repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Raesp gateway design in my own project?

Yes, under the terms of its GPL-3.0 license, which cziter15 chose for the repository.

Can I test firmware for the Raesp gateway 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.
