What’s published M5Stack publishes a schematic PDF (rev V0.6.1, pre-release) for the RPi-CM0-based CardputerZero; no PCB source, Gerbers, BOM, or 3D enclosure files found.

Research notes CardputerZero is a Kickstarter/pre-release M5Stack product; the CardputerZero GitHub org (Template, launcher, AppBuilder, etc.) is all app/OS software, not hardware. Confirmed schematic PDF returns 200; no matching product code found in the m5stack/M5_Hardware repo tree yet, so no 3D/structure files could be verified as existing.

M5Stack marks the packaging, software and documentation as work in progress. The current documentation specifies a 1750 mAh battery, replacing the archive’s 1500 mAh figure.
The base device has no documented integrated LoRa or CC1101 radio. Additional functions depend on expansion hardware.
Capability corrected 2026-09-19: this entry's specifications name Bluetooth, but the Bluetooth capability was not set, so the filter and the comparison table under-reported it.
