RFW26: common questions

What microcontroller does the RFW26 use?

The RFW26 is built around the ESP01, from the ESP8266 family.

How big is the RFW26 PCB?

The RFW26 measures 100 × 50 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the RFW26?

41 components, from 31 distinct parts. The full bill of materials is listed on this page.

Where can I download the RFW26 design files?

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

Can I use the RFW26 design in my own project?

The repository has no license, so all rights stay with IoTCloudStudio. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the RFW26 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.
