About the Bluey PCB

Bluey is an open source Nordic nRF PCB design by electronut, published on GitHub under the CC-BY-4.0 license. It is a 2-layer board measuring 59.2 × 40 mm, with 72 components from 44 distinct parts.

Its main chip is the nrf52832, from the Nordic nRF family. Other key parts include the CP2104, AP2112K, HDC1010, APDS9300-020 and LSM6DS3. By type, the board carries 24 capacitors, 17 resistors, 9 ICs, 5 connectors, 3 switches and 3 inductors.

It belongs with the iot & wireless, sensors and dev boards & breakouts designs in this gallery.

From the project

Nordic nRF52832 BLE development board with sensors.

Bluey is an Open Source BLE (Bluetooth Low Energy) development board with Temperature, Humidity, Ambient Light and Accelerometer sensors.

Bluey uses the Nordic nRF52832 BLE SoC (System on a Chip) which has an ARM Cortex-M4F CPU and a 2.4 GHz radio that supports BLE and other proprietary wireless protocols. It also supports NFC, and in fact the board comes with a built-in NFC PCB antenna.

Bluey: common questions

What microcontroller does the Bluey use?

The Bluey is built around the nrf52832, from the Nordic nRF family.

How big is the Bluey PCB?

The Bluey measures 59.2 × 40 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Bluey?

72 components, from 44 distinct parts. The full bill of materials is listed on this page.

Where can I download the Bluey design files?

From the electronut/ElectronutLabs-bluey repository on GitHub, which has the KiCad layout; the links under Design files point to each one.

Can I use the Bluey design in my own project?

Yes, under the terms of its CC-BY-4.0 license, which electronut chose for the repository.

Can I test firmware for the Bluey 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.
