Fragaria extend: common questions

What microcontroller does the Fragaria extend use?

The Fragaria extend is built around the ESP-12F(ESP8266MOD), from the ESP8266 family.

How big is the Fragaria extend PCB?

The Fragaria extend measures 40 × 75 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Fragaria extend?

80 components, from 30 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 Fragaria extend design files?

From the Zhang-JK/Fragaria-Cake 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 Fragaria extend design in my own project?

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

Can I test firmware for the Fragaria extend 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.
