EKO MyMiner: common questions

What microcontroller does the EKO MyMiner use?

The EKO MyMiner is built around the 25MHZ, from the ESP32 family.

How big is the EKO MyMiner PCB?

The EKO MyMiner measures 140 × 100 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the EKO MyMiner?

66 components, from 42 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 EKO MyMiner design files?

From the phil31/BOX-Miner 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 EKO MyMiner design in my own project?

Yes, under the terms of its GPL-3.0 license, which phil31 chose for the repository.

Can I test firmware for the EKO MyMiner without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
