## Summary Migrates the legacy monospaced README.txt for the **Arduino M0** development board (Microchip ATSAMD21G18A MCU) to standard Sphinx rST documentation format in index.rst, removing the .. include:: README.txt :literal: raw inclusion. Key documentation contents added: - Board overview and comparison between Arduino M0, Arduino M0 Pro, Arduino Zero, and compatible third-party variants (Wemos SAMD21 M0, RobotDyn SAMD21 M0). - Operating voltage specifications and 3.3V I/O pin caution. - Full hardware specs: 32-bit ARM Cortex-M0+ @ 48 MHz, 256 KB Flash, 32 KB SRAM, internal RC oscillator + DFLL48M clock architecture. - LED indicator table for CONFIG_ARCH_LEDS states on PA17. - Serial console pinout and connection guide for SERCOM5 (PB22 TXD / PB23 RXD) at 115200 8N1. - Native USB CDC/ACM serial console guide (usbnsh). - Board configurations overview ( sh, usbnsh) and build instructions. - Flashing and debugging section covering OpenOCD with CMSIS-DAP / Atmel-ICE, ST-Link (interface/stlink.cfg), Segger J-Link (interface/jlink.cfg), and GDB. - Explicit note on bootloader offset limitations (explaining why SWD at 0x00000000 is required by default due to scripts/flash.ld). Addresses #11077 Part of #15737 ## Impact Documentation only. No impact on existing source code, drivers, or build logic. ## Testing - Validated rST syntax and rendering using docutils with 0 errors and 0 warnings. - Verified commit style and formatting with ools/checkpatch.sh -g HEAD (0 errors, 0 warnings). -- This is an automated message from the Apache Git Service.
