Jiran ble lite: common questions

What microcontroller does the Jiran ble lite use?

The Jiran ble lite is built around the HOLYIOT-18010-NRF52840_Simple, from the Nordic nRF family.

How big is the Jiran ble lite PCB?

The Jiran ble lite measures 329.7 × 104.7 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jiran ble lite?

152 components, from 16 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jiran ble lite design files?

From the Ladniy/jiran-ble-lite repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Jiran ble lite design in my own project?

Yes, under the terms of its CERN-OHL-P-2.0 license, which Ladniy chose for the repository.

Can I test firmware for the Jiran ble lite without the hardware?

Yes. HardLabs builds a simulation of the board from its netlist and BOM, so you can run and debug Nordic nRF firmware against it before you order a PCB.
