AOML AB 2.3: common questions
What microcontroller does the AOML AB 2.3 use?
The AOML AB 2.3 is built around the PIC18F8722-I/PT, from the PIC family.
How big is the AOML AB 2.3 PCB?
The AOML AB 2.3 measures 309.9 × 99.7 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the AOML AB 2.3?
108 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the AOML AB 2.3 design files?
From the cxs1529/XBT_Autolauncher_PCB repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.
Can I use the AOML AB 2.3 design in my own project?
The repository has no license, so all rights stay with cxs1529. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the AOML AB 2.3 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.
