Wifi2can: common questions
What microcontroller does the Wifi2can use?
The Wifi2can is built around the ESP-12, from the ESP8266 family.
How big is the Wifi2can PCB?
The Wifi2can measures 65 × 40 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Wifi2can?
55 components, from 27 distinct parts. The full bill of materials is listed on this page.
Where can I download the Wifi2can design files?
From the zhangxuhong1024/wifi2can repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Wifi2can design in my own project?
The repository has no license, so all rights stay with zhangxuhong1024. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Wifi2can 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.
