Mddm badge: common questions
What microcontroller does the Mddm badge use?
The Mddm badge is built around the PIC10F322-IOT, from the PIC family.
How big is the Mddm badge PCB?
The Mddm badge measures 26.8 × 31.4 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Mddm badge?
20 components, from 9 distinct parts. The full bill of materials is listed on this page.
Where can I download the Mddm badge design files?
From the polaracep/soldering-kits repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the Mddm badge design in my own project?
Yes, under the terms of its AGPL-3.0 license, which polaracep chose for the repository.
Can I test firmware for the Mddm badge without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug PIC firmware against it before you order a PCB.
