UProgrammer-Hardware: common questions

What microcontroller does the UProgrammer-Hardware use?

The UProgrammer-Hardware is built around the ESP-12E, from the ESP8266 family.

How big is the UProgrammer-Hardware PCB?

The UProgrammer-Hardware measures 76.2 × 50.8 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the UProgrammer-Hardware?

72 components, from 37 distinct parts. The full bill of materials is listed on this page.

Where can I download the UProgrammer-Hardware design files?

From the MackPI/UProgrammer-Hardware repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the UProgrammer-Hardware design in my own project?

Yes, under the terms of its MIT license, which MackPI chose for the repository.

Can I test firmware for the UProgrammer-Hardware 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.
