BAI1: common questions
What microcontroller does the BAI1 use?
The BAI1 is built around the ESP-12E, from the ESP8266 family.
How big is the BAI1 PCB?
The BAI1 measures 203.2 × 88.9 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the BAI1?
52 components, from 18 distinct parts. The full bill of materials is listed on this page.
Where can I download the BAI1 design files?
From the leevawns/MATOME_CONTROL_BOX repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the BAI1 design in my own project?
The repository has no license, so all rights stay with leevawns. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the BAI1 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.
