About the Ecad coffeecaller PCB

Ecad coffeecaller is an open source Nordic nRF PCB design by tiacsys, published on GitHub under the CERN-OHL-S-2.0 license. It is a 2-layer board measuring 65.6 × 54 mm, with 78 components from 34 distinct parts.

Its main chip is the NRF52840-QIAA-R, from the Nordic nRF family. Other key parts include the HYG-8503A-5027, XC6206P332MR, SHT40-CD1B-R3 and ANT3216LL00R2400A. By type, the board carries 28 capacitors, 14 resistors, 6 diodes, 5 ICs, 5 LEDs and 4 switches.

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

From the project

CoffeeCaller. Once a nice office gadget it now evolved to a small development board for the Nordic nRF52840.

This repository holds the KiCad design files for the CoffeeCaller. Once a nice office gadget it now evolved to a small development board for the Nordic nRF52840 featuring buttons, LEDs, buzzer and an onboard temperature sensor.

SoC: Nordic nRF52840 - 64 MHz Cortex-M4 with FPU - 1 MB Flash, 256 KB RAM - 2.4 GHz Transceiver

Power - 5 V power supply via USB-C connector - LDO to provide 3.3 V with 200 mA

Ecad coffeecaller: common questions

What microcontroller does the Ecad coffeecaller use?

The Ecad coffeecaller is built around the NRF52840-QIAA-R, from the Nordic nRF family.

How big is the Ecad coffeecaller PCB?

The Ecad coffeecaller measures 65.6 × 54 mm, has 2 copper layers and is 1.6 mm thick.

How many components are on the Ecad coffeecaller?

78 components, from 34 distinct parts. The full bill of materials is listed on this page.

Where can I download the Ecad coffeecaller design files?

From the tiacsys/ecad-coffeecaller repository on GitHub, which has the KiCad layout and the schematic; the links under Design files point to each one.

Can I use the Ecad coffeecaller design in my own project?

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

Can I test firmware for the Ecad coffeecaller 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.
