Jantteri main: common questions
What microcontroller does the Jantteri main use?
The Jantteri main is built around the BQ24610, from the ESP32 family.
How big is the Jantteri main PCB?
The Jantteri main measures 78.5 × 34.3 mm, has 2 copper layers and is 1.6 mm thick.
How many components are on the Jantteri main?
44 components, from 38 distinct parts, with part numbers taken from the project's own BOM. The full bill of materials is listed on this page.
Where can I download the Jantteri main design files?
From the OJ2016/pcb-common repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.
Can I use the Jantteri main design in my own project?
The repository has no license, so all rights stay with OJ2016. Use it as a reference, and ask the author before reusing the design.
Can I test firmware for the Jantteri main without the hardware?
Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug ESP32 firmware against it before you order a PCB.
