Leditaulu: common questions
What microcontroller does the Leditaulu use?
The Leditaulu is built around the ESP-12E, from the ESP8266 family.
How big is the Leditaulu PCB?
The Leditaulu measures 56 × 78 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Leditaulu?
49 components, from 24 distinct parts. The full bill of materials is listed on this page.
Where can I download the Leditaulu design files?
From the jvsalo/leditaulu repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the Leditaulu design in my own project?
Yes, under the terms of its MIT license, which jvsalo chose for the repository.
Can I test firmware for the Leditaulu 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.
