Hal9k badge: common questions

What microcontroller does the Hal9k badge use?

The Hal9k badge is built around the ESP-12F, from the ESP8266 family.

How big is the Hal9k badge PCB?

The Hal9k badge measures 100 × 109.1 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Hal9k badge?

110 components, from 36 distinct parts. The full bill of materials is listed on this page.

Where can I download the Hal9k badge design files?

From the Hal9k-dk/Hacker_Badge repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Hal9k badge design in my own project?

The repository has no license, so all rights stay with Hal9k-dk. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the Hal9k badge 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.
