About the MosaicHAT-Station PCB

MosaicHAT-Station is an open source Raspberry Pi PCB design by taroz, published on GitHub. It is a 4-layer board measuring 85 × 56.5 mm, with 45 components from 24 distinct parts.

Its main chip is the PRT-14017, from the Raspberry Pi family. Other key parts include the 410322, LD1117AS33TR, SN74AVC4T245PWR and SN74LVC1G126DRLR. By type, the board carries 12 diodes, 8 connectors, 8 capacitors, 7 resistors, 4 ICs and 2 jumpers.

It belongs with the rf & radio, displays & leds and power & battery designs in this gallery.

From the project

mosaicHAT+ GNSS antenna + Raspberry Pi + Touch display + Battery + Case

1. Mount the Raspberry Pi on the touch display. Then mount the mosaicHAT on the Rasberry Pi using the M2.5 18mm spacers and screws.

2. Fix the GNSS antenna using the M2.5 screws. Connect the SMA cable. Mount the touch display on the case using the M2.5 screws.

3. Modify the battery holder to connect the DCDC converter to the battery. Fix the battery holder to the back plate. Then connect the power cable to the mosaicHAT. Fix the front plate using the M3 screws.

MosaicHAT-Station: common questions

What microcontroller does the MosaicHAT-Station use?

The MosaicHAT-Station is built around the PRT-14017, from the Raspberry Pi family.

How big is the MosaicHAT-Station PCB?

The MosaicHAT-Station measures 85 × 56.5 mm, has 4 copper layers and is 1.6 mm thick.

How many components are on the MosaicHAT-Station?

45 components, from 24 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 MosaicHAT-Station design files?

From the taroz/mosaicHAT-Station repository on GitHub, which has the KiCad layout and the BOM; the links under Design files point to each one.

Can I use the MosaicHAT-Station design in my own project?

The repository has no license, so all rights stay with taroz. Use it as a reference, and ask the author before reusing the design.

Can I test firmware for the MosaicHAT-Station without the hardware?

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