About the Jiran ble PCB

Jiran ble is an open source Nordic nRF PCB design by Ladniy, published on GitHub under the MIT license. It is a 2-layer board measuring 6.1 × 56.3 mm, with 170 components from 23 distinct parts.

Its main chip is the HOLYIOT-18010-NRF52840_Simple, from the Nordic nRF family. Other key parts include the AP2112K-3.3 and TP4054. By type, the board carries 60 switches, 58 diodes, 16 resistors, 10 connectors, 6 ICs and 4 LEDs.

It belongs with the iot & wireless and keyboards designs in this gallery.

From the project

Wireless version of my keyboard, based on nRF

Wireless version of my keyboard, based on Holyiot-18010 (nRF52840) module.

The main goal of this project is a fast and cheap production of a wireless ergonomic keyboard, mostly without soldering.

Unfortunately, at the moment JLC does not have all the necessary components in basic inventory, so you need to pay an additional 3$ for each component from the extended inventory.

Jiran ble: common questions

What microcontroller does the Jiran ble use?

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

How big is the Jiran ble PCB?

The Jiran ble measures 6.1 × 56.3 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Jiran ble?

170 components, from 23 distinct parts. The full bill of materials is listed on this page.

Where can I download the Jiran ble design files?

From the Ladniy/jiran-ble 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 design in my own project?

Yes, under the terms of its MIT license, which Ladniy chose for the repository.

Can I test firmware for the Jiran ble 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.
