## Blueprint

**Schematics published.** M5Stack publishes core-board and expansion-board schematic PDFs for Core2; no KiCad/Altium source, Gerbers, or BOM. Public schematic is labelled v1.0, the listed product is v1.3.

### Key parts

| Part | Role | Datasheet |
|---|---|---|
| ESP32-D0WDQ6-V3 | MCU (dual-core 240 MHz, Wi-Fi/BT) | https://m5stack-doc.oss-cn-shenzhen.aliyuncs.com/644/esp32_datasheet_en.pdf |
| MPU-6886 | 6-axis IMU (per docs.m5stack.com/en/core/core2) | https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/core/MPU-6886-000193%2Bv1.1_GHIC_en.pdf |
| BM8563 | RTC | https://m5stack.oss-cn-shenzhen.aliyuncs.com/resource/docs/datasheet/core/BM8563_V1.1_cn.pdf |

_Notes:_ docs.m5stack.com/en/core/core2 (the generic Core2 doc page) is what serves the schematic and lists MPU-6886 as the IMU, not BMI270; only a v1.0 schematic PDF was found even though the product listed is 'v1.3' (M5Stack has not published a separate v1.3-specific schematic PDF that I could locate). Core2 v1.3 case STL confirmed present in m5stack/M5_Hardware.
