MeshCrossway is an open-source, ESP32-based portable communicator designed to connect travelers and search-and-rescue teams across Meshtastic and MeshCore networks in parallel, with dedicated LoRa radios, a touchscreen interface, GNSS positioning, and offline messaging.
MeshCrossway RevA LAYOUT A is an open-source printed circuit board by Renbrant, from the Renbrant/MeshCrossway repository on GitHub, published under the MIT licence. It is a 4-layer board of 160 × 94 mm with 39 parts on 27 nets, routed with 151 tracks and 98 vias.
Its parts include 10 capacitors, 7 resistors, 4 ICs, 2 diodes and 2 connectors. It belongs with the radio and wireless boards of this library.

PCB layout alternatives
The MeshCrossway Rev A schematic is shared by multiple PCB floorplans.
Layout A
Status: preserved alternative.
The earlier engineering layout explored a wider 4-layer carrier with the radios on opposite sides and GNSS separated from the radio power section. It is retained as a reference, not the active direction.
Layout B
Status: active.
Layout B starts from a blank PCB and targets a 2-layer carrier:
F.Cu: components, power, UART/I2C/PPS and most routing.
B.Cu: nearly continuous GND plane.
Avoid bottom-layer routing beneath the XIAO/Wio RF modules and GNSS where it would cut the return plane.
Begin with J1, U2, U3 and U4 only.
Freeze the mechanical/RF floorplan before placing support components or routing.

Questions
How big is the MeshCrossway RevA LAYOUT A PCB?
It measures 160 × 94 mm and has 4 copper layers, 1.6 mm thick.
What parts does the MeshCrossway RevA LAYOUT A use?
39 parts. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the MeshCrossway RevA LAYOUT A KiCad files?
From the Renbrant/MeshCrossway repository on GitHub, at the commit this page was made from: the board is hardware/kicad/layouts/MeshCrossway_RevA_LAYOUT_A.kicad_pcb and its schematic hardware/kicad/MeshCrossway_RevA.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the MeshCrossway RevA LAYOUT A design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
