Shihen: common questions
What microcontroller does the Shihen use?
The Shihen is built around the ESP-12E, from the ESP8266 family.
How big is the Shihen PCB?
The Shihen measures 89 × 36 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Shihen?
50 components, from 29 distinct parts. The full bill of materials is listed on this page.
Where can I download the Shihen design files?
From the likeablob/shihen repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Shihen design in my own project?
Yes, under the terms of its MIT license, which likeablob chose for the repository.
Can I test firmware for the Shihen 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.
