    1. Vol 1 M5Stack Cardputer Zero Volume 1 — Overview, Family Lineage, and Decision Tree What it actually is — a Raspberry Pi CM0 pocket Linux computer — where it branches off the Cardputer family, the Zero-vs-ADV-vs-cyberdeck decision tree, and depth indices into Vols 2-12
    2. Vol 2 M5Stack Cardputer Zero Volume 2 — Hardware Raspberry Pi CM0 (RP3A0/BCM2837 quad-A53) silicon, ST7789v3 display + 46-key matrix + ES8389 audio + 9-axis IMU, power tree, Cap EXT bus, schematic-style walk of the confirmed Linux pocket computer
    3. Vol 3 M5Stack Cardputer Zero Volume 3 — External Interfaces 2× USB-C + USB-A host, the microSD boot device, Grove, plus Ethernet / HDMI / the Cap EXT 14-pin bus / audio / IR — the richest external I/O in the Cardputer family, all on the Linux stack
    4. Vol 4 M5Stack Cardputer Zero Volume 4 — Expansion & Module Ecosystem The Cap EXT 14-pin bus, Grove HY2.0, and Linux/USB peripherals — three real expansion paths on a Pi-CM0 pocket Linux box
    5. Vol 5 M5Stack Cardputer Zero Volume 5 — Power Profile Confirmed 1500 mAh LiPo + BQ27220 fuel gauge, USB-C charging, a Linux-SoC power model (no MCU deep sleep), and hours-not-days runtime
    6. Vol 6 M5Stack Cardputer Zero Volume 6 — Software & OS Ecosystem The Linux stack: Raspberry Pi OS / Debian aarch64 on the CM0, the cardputer-zero-shell Wayland desktop, the .deb AppStore + app catalog, and the Linux-native security toolchain that replaces the old ESP32 firmware story — see Vol 4 for the Cap EXT bus the RF tools ride on
    7. Vol 7 M5Stack Cardputer Zero Volume 7 — Programming & App Development (Linux) Program it like a Raspberry Pi: native gcc/Python/Rust on Debian aarch64, plus the czdev AppBuilder + SDL2 emulator for on-screen LVGL apps
    8. Vol 8 M5Stack Cardputer Zero Volume 8 — OS Imaging, Boot & Recovery Writing a Raspberry Pi OS image to microSD, the CM0 boot chain (u-boot → kernel → device-tree overlays), headless setup, card backup/clone, and re-imaging recovery
    9. Vol 9 M5Stack Cardputer Zero Volume 9 — Use Cases and Recipes Linux teaching machine, network drop box, Linux-native pentest workflows, retro emulation + IoT — the CM0 pocket-computer's real use scenarios
    10. Vol 10 M5Stack Cardputer Zero Volume 10 — Custom App Development Building Linux apps for the CM0: the czdev/AppBuilder LVGL flow, .deb packaging to the AppStore, and Linux-native drop-box services
    11. Vol 11 M5Stack Cardputer Zero Volume 11 — Operational Posture Regional rules for the on-module 2.4 GHz (+ optional sub-GHz) radios, LiPo small-cell safety, education posture, fleet-ops chain of custody, the Linux-computer security posture, and legal/ethics
    12. Vol 12 M5Stack Cardputer Zero Volume 12 — Cheatsheet Laminate-ready field card for the CM0 Linux pocket computer — confirmed quick-facts, receipt checks, OS imaging, czdev quick-start, battery math, region rules, troubleshooting, pre-engagement checklist
