TCKB: common questions
What microcontroller does the TCKB use?
The TCKB is built around the STM32L053C8T6, from the STM32 family.
How big is the TCKB PCB?
The TCKB measures 285 × 94.6 mm, has 2 copper layers and is 1.6002 mm thick.
How many components are on the TCKB?
268 components, from 152 distinct parts. The full bill of materials is listed on this page.
Where can I download the TCKB design files?
From the Ced67/TCKB_Kicad repository on GitHub, which has the KiCad layout; the links under Design files point to each one.
Can I use the TCKB design in my own project?
The repository has no license, so all rights stay with Ced67. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the TCKB without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug STM32 firmware against it before you order a PCB.
